Please contact your local representative. Will be supplied as "poly BSA Type II *SQ". Unit of measure is "g active ingredient". Poly BSA Type II is produced from bovine serum albumine (BSA) by polymerization. Its surface is chemically modified by succinylation, and the negative charge of the Poly BSA Type II eliminates hydrophobic interactions.The Poly BSA Type II solution contains protein, potassium-phosphate buffer, and preservatives (chloroacetamide, methylisothiazolone and sucrose). en Polymeric BSA Type II 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): 25-55 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.
