Abstract
In the first part of this publication, the results from an international study evaluating the precision (i.e., repeatability and reproducibility) of N-glycosylation analysis using capillary electrophoresis of APTS-labeled N-glycans were presented. The corresponding results from ultra-high performance liquid chromatography (UHPLC) with fluorescence detection are presented here from 12 participating sites. All participants used the same lot of samples, reagents, and columns to perform the assays. Elution time, peak area and peak area percent values were determined for all peaks ≥0.1% peak area, and statistical analysis was performed following ISO 5725-2 guideline principles. The results demonstrated adequate reproducibility, within any given site as well across all sites, indicating that standard UHPLC-based N-glycan analysis platforms are appropriate for general use.

Abstract
An international team that included 20 independent laboratories from biopharmaceutical companies, universities, analytical contract laboratories and national authorities in the United States, Europe and Asia was formed to evaluate the reproducibility of sample preparation and analysis of N-glycans using capillary electrophoresis of 8-aminopyrene-1,3,6-trisulfonic acid (APTS)-labeled glycans with laser induced fluorescence (CE-LIF) detection (16 sites) and ultra high-performance liquid chromatography (UHPLC, 12 sites; results to be reported in a subsequent publication). All participants used the same lot of chemicals, samples, reagents, and columns/capillaries to run their assays. Migration time, peak area and peak area percent values were determined for all peaks with >0.1% peak area. Our results demonstrated low variability and high reproducibility, both, within any given site as well across all sites, which indicates that a standard N-glycan analysis platform appropriate for general use (clone selection, process development, lot release, etc.) within the industry can be established.

Abstract
Immunoglobulin G (IgG) crystallizable fragment (Fc) glycosylation is crucial for antibody effector functions, such as antibody-dependent cell-mediated cytotoxicity, and for their pharmacokinetic and pharmacodynamics behavior. To monitor the Fc-glycosylation in bioprocess development, as well as product characterization and release analytics, reliable techniques for glycosylation analysis are needed. A wide range of analytical methods has found its way into these applications. In this study, a comprehensive comparison was performed of separation-based methods for Fc-glycosylation profiling of an IgG biopharmaceutical. A therapeutic antibody reference material was analyzed 6-fold on 2 different days, and the methods were compared for precision, accuracy, throughput and other features; special emphasis was placed on the detection of sialic acid-containing glycans. Seven, non-mass spectrometric methods were compared; the methods utilized liquid chromatography-based separation of fluorescent-labeled glycans, capillary electrophoresis-based separation of fluorescent-labeled glycans, or high-performance anion exchange chromatography with pulsed amperometric detection. Hydrophilic interaction liquid chromatography-ultra high performance liquid chromatography of 2-aminobenzamide (2-AB)-labeled glycans was used as a reference method. All of the methods showed excellent precision and accuracy; some differences were observed, particularly with regard to the detection and quantitation of minor glycan species, such as sialylated glycans.

Abstract
BACKGROUND As immunofluorescence experiments become more complex, the demand for new dyes with different properties increases. Fluorescent dyes with large Stoke's shifts that are very bright and have low background binding to cells are especially desirable. We report on the properties of the resonance energy tandems of phycoerythrin and allophycocyanin (PE-APC). PE-APC is the original fluorescence resonance energy tandem dye described in the literature, but it has not been utilized because of the difficulty of synthesizing and preparing a consistent product. METHODS PE-APC complexes comprising different ratios of the two phycobiliproteins conjugated to streptavidin were synthesized using standard protein-protein conjugation chemistry. The PE-APC streptavidins were evaluated for flow cytometric analysis. They were compared directly to Cy5PE conjugates because Cy5PE is the fluorophore that is spectrally most like the PE-APC. RESULTS PE-APC complexes showed the expected fluorescence spectral properties of a tandem: excitation was excellent at 488 nm (and best at the PE excitation maximum) and emission was greatest at the APC emission maximum at about 660 nm. The efficiency of transfer of energy from PE to APC was about 90%. CONCLUSION PE-APC can be considered an excellent substitute for Cy5PE. Compared with Cy5PE, PE-APC has similar brightness (in staining experiments), slightly greater compensation requirements with PE but much lower compensation with Cy5.5PE or Cy5.5PerCP, and lower nonspecific background binding. PE-APC is a useful alternative to Cy5PE, especially in applications in which the use of Cy5 is impractical. Cytometry 44:24-29, 2001. Published 2001 Wiley-Liss, Inc.
