Description Bovine Serum Albumin (BSA) is a high purity, lyophilized "Fraction V" powder derived from the plasma of MPI-inspected healthy New Zealand origin animals. The albumin is isolated from other plasma protein products and lipids by a unique proprietary, non-solvent procedure. The separation process includes a modified Cohn / heat-shock procedure designed to inactivate proteases and other potentially interfering enzymes. Further processing such as extensive membrane dialysis and filtration, minimizes analytes that can cause background interference in sensitive in vitro diagnostic (IVD) assays as well as inhibition in sensitive cell and microbial culture systems. Typical purity levels are in excess of 99%. New Zealand Source Standard Grade bovine albumin product is an economical choice that is ideal for most diagnostic and research applications. Applications Protease-sensitive Immunoassays such as RIA, EIA, Fluorescent and Chemiluminescent Protein Standard, Diluent Protein, Conjugate or Enzyme Stabilizer Hybridization Selected Cell Culture applications Features/Benefits High Purity, Low Interference, Low Background Virtually No Detectable Protease Activity, Ensures Assay Integrity “Closed Loop” Manufacturing* – Minimizes Contamination and Maximizes Reproducibility Superior Solubility/Filterability for Ease of Use Product Development and Technical Services Designed for maximum responsiveness and Flexibility Manufactured from MPI inspected Bovine Plasma Manufactured According to FDA cGMPs Validated for Prion (TSE) Clearance Specifications Protein (dry basis) ≥ 96.0% Purity (albumin) ≥ 98% Solubility (4% water) Clear/slightly hazy Moisture ≤ 5.0% pH (10% water) 6.5 to 7.5 Ash Protease ≤ 0.005 Units/mg Endotoxin ≤ 3 EU/mg IgG Not Detected Physical Characteristics Bovine Serum Albumin is a highly soluble yellow to green with tan to green cast lyophilized powder. A solution of up to 30% in de-ionized water is clear to slightly hazy and virtually particulate-free. Storag Recommendations Store sealed in a cool, dry environment for 3 years, and up to 5 years with re-qualification.

牛血清白蛋白适用于多种生化应用，包括酶联免疫吸附试验（ELISA）、免疫印迹和免疫组织化学。常用作阻断试剂；尤其适用于对酪蛋白敏感的抗体，如磷酸化特异性抗体。还可用作细胞和微生物培养的营养剂。在限制性消化中，BSA 用于在 DNA 消化过程中稳定某些酶，并防止酶粘附在反应管和其他容器上。通过比较未知量的蛋白质和已知量的 BSA，常用于确定其他蛋白质的数量。
