Poly BSA Typ I *SQ 11866737103 Not Available Reagents, kits en 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). en 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). en Appearance: Yellowish, clear to slightly opalescent solution (frozen) pH value (+25°C): 6.8-7.2 Protein (Biuret): ≥40 mg/mL Particle size (Photon correlations spectrometry): 15-45 nm Country of origin: USA pH 4.5 treatment (up to 3 hours): Corresponds to specification Stability: At -15 to -25°C within specification range for 24 months.
