Analytical Development

With top expertise in protein analytics, KBI has successfully completed over 3300 analytical projects for more than 300 customers and more than 130 distinct molecules. Our experience includes antibodies (IgG1, IgG4, IgM, FAb, ADC, Fc fusion), enzymes, cytokines, growth factors, highly glycosylated proteins, protein vaccines, PEGylated proteins, conjugates, peptides and other proteins. KBI expertise includes HPLC, CE, ELISA, UV-Vis, mass spectrometry, light scattering, biophysical characterization (DSC, CD, FTIR, fluorescence), binding assays (ELISA, Biacore, Forte Bio), glycan analyses, cell based assays, and others. We routinely provide STAT analytical support for process development (e.g., DOE sample analysis) and manufacturing (HPLC and other methods for titer, purity, etc.).
