PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2021; 246:119016. [PMID: 33038854 DOI: 10.1016/j.saa.2020.119016] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 09/23/2020] [Accepted: 09/25/2020] [Indexed: 06/11/2023]
Abstract
Utilizing fluorescence spectroscopy, non-covalent and covalent interactions of L-cys@CdTe quantum dots to bovine serum albumin (BSA), cytochrome c and trypsin were investigated. L-cys@CdTe QDs with the emission maximum at 530 nm and an average diameter of 2.6 nm were synthesized in the aqueous medium. Formaldehyde, N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDC) with N-hydroxysuccinimide (NHS), and glutaraldehyde was applied as cross-linkers. In the case of both electrostatic and covalent strategies PARAFAC, as a powerful multi-way chemometrics technique, was utilized to analyze fluorescence excitation-emission (EEM) spectra. For non-covalent and covalent bonding, two and three significant components composed the PARAFAC models. Resolved EEM shows that in the presence of formaldehyde, a new component with an emission peak similar to BSA was obtained. Using EDC-NHS cross-linker, the fluorescence peak of the newly formed component was in a distinct wavelength with similar emission intensity, compared to L-cys@CdTe QDs and BSA. Employing glutaraldehyde, a distinguished component was easily detected at emission wavelengths higher than that of L-cys@CdTe QDs and proteins. It was concluded that the choice of cross-linker is a critical step to create different emission spectra when dealing with nano-bio-conjugations. This study shows that glutaraldehyde cross-linker leads to increase sensitivity, selectivity, and accuracy of protein analysis.

Abstract
Flavonoids are plant products abundant in every day diet and claimed to be beneficial for human health. After absorption, flavonoids are transported by the serum albumin (SA), the most abundant carrier blood protein, through formation of flavonoids-SA complex. This review deals with the current state of knowledge on flavonoids-SA complex over the past 10 years, mainly involved multi-spectroscopic techniques and molecular dynamics simulation studies to explore the binding mechanism, thermodynamics and structural aspects of flavonoids binding to SA. Especially, the novel method, capillary electrophoresis, high performance affinity chromatography approach, native mass spectrometry and microscale thermophoresis used in characterization of the interaction between flavonoids and SA as well as flavonoid-based fluorescent probe for SA measurement are also included in this review.

[PMID: 30785082 DOI: 10.1016/j.jchromb.2019.02.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Revised: 02/07/2019] [Accepted: 02/09/2019] [Indexed: 11/26/2022]
Abstract
The aim of the present study was to purify the natural chlorogenic acid (CGA) monomer from Heijingang potatoes and investigate its interaction with recombinant human serum albumin (rHSA). The potato extract (PE) was purified using macroporous resins and solvent, and the CGA monomer was subsequently isolated using semipreparative liquid chromatography (SP-LC). The purity and structure of the CGA monomer was analyzed by high-performance liquid chromatography (HPLC) and nuclear magnetic resonance (NMR). The interaction between the CGA monomer and rHSA was studied using fluorescence spectroscopy and molecular docking. HPLC analysis indicates that the CGA monomer had a retention time of 5.368 min and a purity of 97.9%, the presence of which was confirmed by NMR. The molecular docking and fluorescence spectroscopy demonstrate that CGA had a static quenching effect on rHSA with one binding site, and the range of K values was 7.14 × 103 to 1.56 × 104 M-1. This simple and efficient extract coupled with SP-LC has the potential for use in the extraction and purification of CGA in pilot or large-scale operations.
