IgG Purity/Heterogeniety Assay Kit

Reference: ABS-A10663

Includes IgG Control Standard 1-pack and all chemistries.
The IgG Purity/Heterogeneity Assay has been developed for researchers employed in industrial biotechnology who are developing and manufacturing IgG reagents for research, diagnostic and therapeutic use. 

This assay has been specified for use on the PA 800 Plus to assess the purity and heterogeneity of IgG reagents in both a reduced and non-reduced state. The methodology involves heat-denaturing a specified concentration of IgG (both reduced and non-reduced) in the presence of SDS, and separating these proteins by size using high-resolution capillary gel electrophoresis technology. This assay will detect impurities as low as 0.1% and includes an IgG control with a designated quantity of non-glycosylated heavy chain to test both the resolution and quantitation suitability of the assay prior to running unknowns
