Novel multimodal cation-exchange membrane for the purification of a single-chain variable fragment from Pichia pastoris supernatant. J Chromatogr A 2024; 1718:464682. [PMID: 38341900 DOI: 10.1016/j.chroma.2024.464682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 01/22/2024] [Accepted: 01/25/2024] [Indexed: 02/13/2024]
Abstract
A novel salt-tolerant cation-exchange membrane, prepared with a multimodal ligand, 2-mercaptopyridine-3-carboxylic acid (MMC-MPCA), was examined for its purification properties in a bind-and-elute mode from the high conductivity supernatant of a Pichia pastoris fermentation producing and secreting a single-chain variable fragment (scFv). If successful, this approach would eliminate the need for a buffer exchange prior to product capture by ion-exchange. Two fed-batch fermentations of Pichia pastoris resulted in fermentation supernatants reaching an scFv titer of 395.0 mg/L and 555.7 mg/L, both with a purity of approximately 83 %. The MMC-MPCA membrane performance was characterized in terms of pH, residence time (RT), scFv load, and scFv concentration to identify the resulting dynamic binding capacity (DBC), yield, and purity achieved under optimal conditions. The MMC-MPCA membrane exhibited the highest DBC of 39.06 mg/mL at pH 5.5, with a residence time of 1 min, while reducing the pH below 5.0 resulted in a significant decrease of the DBC to around 2.5 mg/mL. With almost no diffusional limitations, reducing the RT from 2 to 0.2 min did not negatively impact the DBC of the MMC-MPCA membrane, resulting in a significant improvement in productivity of up to 180 mg/mL/min at 0.2 min RT. Membrane fouling was observed when reusing the membranes at 0.2 and 0.5 min RT, likely due to the enhanced adsorption of impurities on the membrane. Changing the amount of scFv loaded onto the membrane column did not show any changes in yield, instead a 10-20 % loss of scFv was observed, which suggested that some of the produced scFv were fragmented or had aggregated. When performing the purification under the optimized conditions, the resulting purity of the product improved from 83 % to approximately 92-95 %.

Abstract
Human epidermal growth factor (hEGF) has multiple biological functions, such as promoting cell proliferation, differentiation, and migration. In addition, it is a very expensive polypeptide with attractive market prospects. However, the production of hEGF needs for high cost to manufacture polypeptide demands reinvestigations of process conditions so as to enhance economic benefits. Improving the expression of soluble hEGF is the fundamental method to reduce the cost. In this study, a non-extracellular engineered strain of expressed hEGF was constructed, using plasmid pET-22b(+) in Escherichia coli. Preliminary fermentation and high cell density cultivation were carried out in shake flasks and in a 5 L bioreactor, respectively. A high yield of 98 ± 10 mg/L of soluble hEGF and a dry cell weight (DCW) of 6.98 ± 0.3 g/L were achieved in shake flasks. Then, fermentation conditions were optimized for large-scale production, while taking into consideration the expensive equipment required for cooling and conforming to industrial standards. A yield of 285 ± 10 mg/L of soluble hEGF, a final cell density of 57.4 ± 2 g/L DCW (OD600 141.1 ± 4.9), and hEGF productivity of 14.3 mg/L/h were obtained using a bioreactor at 32 °C for 20 h. The production method developed in this study for the biosynthesis of soluble hEGF is efficient and inexpensive.

Abstract
Background Cyclin-dependent kinase 4 (CDK4) when hyperactivated drives development and maintenance of most tumour types, thus prompting its use as an essential cancer treatment target and a diagnostic tool. Target-binding molecules, such as single-chain variable fragment (scFv) antibodies, hold tremendous potential for use in a wide range of cancer diagnostic and therapeutic applications. Results A human anti-CDK4 scFv antibody (AK2) derived from a human phage display library was expressed in soluble form in Escherichia coli and shown to be secreted into the culture supernatant. Next, soluble AK2 within culture supernatant was successfully purified using affinity chromatography then was shown, using enzyme-linked immunosorbent assays, to bind to recombinant human CDK4 with high affinity and specificity. Further analyses of AK2 interactions with intracellular components demonstrated that AK2 recognised and interacted specifically with endogenous CDK4 and thus could be useful for detection of CDK4 within tumour cells. Conclusions A novel anti-CDK4 scFv antibody that can recognise and interact specifically with recombinant human CDK4 and endogenous CDK4 in tumour cells was expressed and purified successfully. These results suggest that the anti-CDK4 scFv antibody may serve as a new and promising tool for achieving CDK4-targeted diagnosis, prognosis and treatment of numerous types of cancers.

Optimizing selectivity of anion hydrophobic multimodal chromatography for purification of a single-chain variable fragment. Eng Life Sci 2019; 19:490-501.

Abstract
Single-chain variable fragments (scFv) are widely used in several fields. However, they can be challenging to purify unless using expensive Protein L-based affinity adsorbents or affinity tags. In this work, a purification process for a scFv using mixed-mode (MM) chromatography was developed by design of experiments (DoE) and proteomics for host cell protein (HCP) quantification. Capture of scFv from human embryonic kidney 293 (HEK293) cell feedstocks was performed by hydrophobic charge induction chromatography (MEP HyperCel™), whereafter polishing was performed by anion hydrophobic MM chromatography (Capto Adhere™). The DoE designs of the polishing step included both binding and flow-through modes, the latter being the standard mode for HCP removal. Chromatography with Capto Adhere™ in binding-mode with elution by linear salt gradient at pH 7.5 resulted in optimal yield, purity and HCP reduction factor of 98.9 > 98.5%, and 14, respectively. Totally, 258 different HCPs were removed, corresponding to 84% of identified HCPs. The optimized conditions enabled binding of the scFv to Capto Adhere™ below its theoretical pI, while the majority of HCPs were in the flow-through. Surface property maps indicated the presence of hydrophobic patches in close proximity to negatively charged patches that could potentially play a role in this unique selectivity.

Abstract
Process chromatography forms the core of purification of biotherapeutics. The unparalleled
selectivity that it offers over other alternatives combined with the considerable robustness and scalability
make it the unit operation of choice in downstream processing. It is typical to have three to five chromatography
steps in a purification process for a biotherapeutic. Generally, these steps offer different modes
of separation such as ion-exchange, reversed phase, size exclusion, and hydrophobic interaction. In the
past decade, multimodal chromatography has emerged as an alternative to the traditional modes. It involves
use of more than one mode of separation and typically combines ion-exchange and hydrophobic
interactions to achieve selectivity and sensitivity. Over the last decade, numerous authors have demonstrated
the significant potential that multimode chromatography offers as a protein purification tool. This
review aims to present key recent developments that have occurred on this topic together with a perspective
on future applications of multimodal chromatography.

Abstract
The microorganism Escherichia coli is commonly used for recombinant protein production. Despite several advantageous characteristics like fast growth and high protein yields, its inability to easily secrete recombinant proteins into the extracellular medium remains a drawback for industrial production processes. To overcome this limitation, a multitude of approaches to enhance the extracellular yield and the secretion efficiency of recombinant proteins have been developed in recent years. Here, a comprehensive overview of secretion mechanisms for recombinant proteins from E. coli is given and divided into three main sections. First, the structure of the E. coli cell envelope and the known natural secretion systems are described. Second, the use and optimization of different one- or two-step secretion systems for recombinant protein production, as well as further permeabilization methods are discussed. Finally, the often-overlooked role of cell lysis in secretion studies and its analysis are addressed. So far, effective approaches for increasing the extracellular protein concentration to more than 10 g/L and almost 100% secretion efficiency exist, however, the large range of optimization methods and their combinations suggests that the potential for secretory protein production from E. coli has not yet been fully realized.

Abstract
Osteonecrosis of the femoral head (ONFH) is a major cause of morbidity, and total hip arthroplasty is both traumatic and expensive. Here, we created a gelatine scaffold embedded in uniquely shaped, 3D-printed porous titanium parts, which could attract and promote the proliferation of osteoblasts as well as bone regeneration, as the extracellular matrix (ECM) does in vivo. Interestingly, after hybridisation with platelets, the scaffold exhibited a low yet considerable rate of stable, safe and long-term growth factor release. Additionally, a novel ONFH model was constructed and verified. Scaffolds implanted in this model were found to accelerate bone repair. In conclusion, our scaffold successfully simulates the ECM and considerably accelerates bone regeneration, in which platelets play an indispensable role. We believe that platelets should be emphasised as carriers that may be employed to transport drugs, cytokines and other small molecules to target locations in vivo. In addition, this novel scaffold is a useful material for treating ONFH. An overview of the novel scaffold mimicking the extracellular environment in bone repair. a and b: A gelatine scaffold was cross-linked and freeze-dried within 3D-printed porous titanium. c: Platelets were coated onto the gelatine microscaffold after freeze-drying platelet-rich plasma. d: The microscaffold supported the migration of cells into the titanium pores and their subsequent growth, while the platelets slowly released cell factors, exerting bioactivity.
