General description
Albumin is one of the most extensively utilized proteins in the medical industry. Its availability, inherent stability, and ligand binding capability make albumin a critical raw material in the development and production of many diagnostic tests. With over 65 years of protein fractionation expertise, we are an experienced manufacturer of consistent bovine serum albumin products for the diagnostic and cell culture markets. Our proprietary heat shock and cold solvent fractionation processing technology allows for the delivery of products with high-quality, performance, and reliability.
Application
Probumin® BSA products are fit for use as blockers, protein/antibody (conjugate) stabilizers, and in immunoassays (EIA, RIA and serology systems).
Features and Benefits
- High-quality and reliability. Assurance of consistency in performance and supply.
- Proprietary heat shock and cold solvent fractionation process optimizes the protein yield, purity, and efficacy of BSA. Large batch capacity.
- Safe serum sourcing from USDA-licensed facilities exclusively from U.S. cattle.
- Processed to eliminate or reduce proteases.
