Overview
Poly BSA Type I is produced from bovine serum albumine (BSA) by polymerization. Its surface is chemically modified by acetylation, and the negative charge of the Poly BSA Type I eliminates hydrophobic interactions. The Poly BSA Type I solution contains protein, potassium-phosphate buffer and preservatives (chloroacetamide, methylisothiazolone and sucrose).
+-
Application
Polymeric BSA Type I is used for the elimination of nonspecific polymeric interferences (e.g. for antibodies, conjugates or antigens integrated into infectious disease assays and tumor marker tests).
