Description Sulfhydryl Blocked proprietary manufacturing process effectively blocks free thiol groups to provide a high monomer albumin with less cross-reactivity. Applications include, but are not limited to, Immunoassays (RIA, EIA, etc.), Hybridization, Protein Standard, Diluent, Conjugate or Enzyme Stabilizer. Applications Protease-sensitive Immunoassays (i.e. RIA, EIA, Fluorescent & Chemiluminescent) Protein Standard, Diluent Protein, Conjugate or Enzyme Stabilizer X Thiol sensitive applications (quantification of thiol containing analytes, chemiluminescent assays, or conjugations) Selected cell culture applications Features/Benefits Free of reactive sulfhydryl groups Free of interfering immunoglobulins High purity, low interference, low background Virtually no detectable protease activity, ensures assay integrity Superior solubility/filterability for ease of use Manufactured from MPI inspected bovine plasma Specifications Protein (dry basis) ≥ 98.0% Purity (albumin) ≥ 98% Moisture ≤ 5.0% BIgG None Detected Sodium ≤ 15.0 mg/g Chloride ≤ 6.0 mg/g Free Sulfhydryl Content ≤ 0.1 mol/mol albumin pH (7% Solution)/Temp 6.5-7.5/Ambient Protease None 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。
