Protein A ELISA Kit

Protein A affinity chromatography is widely used for antibody purification. However, the leakage of Protein A, though covalently conjugated to chromatography supports, posts a big problem for antibody based pharmaceutical industry where false results could be generated in immunological assays from contaminated Protein A._x000D_
_x000D_ GenScript Protein A ELISA Kit_x000D_ is developed for accurate quantification of the leakage of native Protein A, recombinant Protein A variants and MabSelect SuRe ^TM_x000D_ in the presence or absence of antibodies. The kit offers pharmaceutical users a sensitive assay to measure mini amount of Protein A in therapeutic antibody products. It also facilitates Protein A resin manufacturers in monitoring leaching characteristics of their resins under specific conditions._x000D_ _x000D_
