• 化粧品の成分用途

  ヘアコンディショニング剤、皮膚コンディショニング剤、皮膜形成剤

• 説明

  Bovine serum albumin is a protein which has a key role in regulating blood colloidal osmotic pressure. A water-soluble protein composed of 583 amino acids, BSA has a calculated molecular weight of 66,430 Daltons. Six α-helices form three homologous domains of BSA. Depending on pH, BSA undergoes reversible conformational isomerization. The native structure of the protein becomes reactive and flexible on heating.
  This BSA product is specifically evaluated and tested for the following properties:
  Very low protease content / protease-free
  Very low fatty acid content / fatty acid-free
  Protease-free BSA is especially useful for applications like:
  Enzyme assays
  Protein-based assays
  Protease-sensitive techniques that include:
  a. Enzyme immunoassay (EIA)
  b. Nucleic acid hybridization
  c. Radioimmunoassay (RIA)

• 化学的特性

  Crystalline powder

• 使用

  Suitable for cell culture media supplement.
  Bovine serum albumin (BSA) Fraction V has uses in many applications such as stabilizing proteins in solution, blocking non-specific binding in immuno-assays, and as a protein standard in various protein assays.
  Stabilizer for proteins and enzymes in solution
  Blocking agent for immuno-assays (ie, western blot, IHC, IF)
  Minimizes non-specific antibody binding
  IgG- and protease-free
  50 g of solid powder
  Bovine serum albumin (BSA) is commonly used as a stabilizing agent for proteins and enzymes, including dilute solutions of antibody. It is also used as a blocking agent to reduce non-specific antibody binding in immuno-detection procedures such as western blotting, immunofluorescence, and IHC. It is also suitable for use in protease sensitive assays such as RIA and EIA, as well as nucleic acid hybridization. This BSA is IgG- and protease-free.

• 主な応用

  Bovine Serum Albumin has been used:
  as a constituent of medium used for the differentiation of human pluripotent stem cells
  in enzyme-linked immunosorbent assay (ELISA) and sandwich ELISA
  to permeabilize fetal cortical cells
  This Sigma A7030 BSA has specifically been used as a component of blocking buffer in a peptide-based ELISA assay for analysis of COVID-19 / SARS-CoV-2 samples (Poh, C.K. et al., Nat. Commun., 11(1), 2806 (2020)).

• 定義

  The word bovine means “cow,” and bovine serum albumin (BSA) is a protein that comes from cows. In particular, BSA is a type of protein called albumin, which is found in large amounts in the blood of cows. Blood is a mixture of red blood cells, which is why blood looks red, and many different types of proteins that are dissolved in water. If the cells in blood were removed, you would be left with a clear liquid, called serum. Thus, BSA is the albumin protein that is found in the blood of cows. In the blood, the job of albumin is to carry other proteins from place to place.

• 一般的な説明

  Bovine serum albumin (BSA) has an important role in the regulation of blood colloidal osmotic pressure. BSA is the major protein in bovine serum, and is composed of 583 amino acids with a calculated molecular weight of 66,430 Daltons. BSA is used in many different applications and fields, such as:
  
  • Protein quantitation (as a standard)
  • Immunochemistry (as a blocking agent)
  • Cell culture (as a nutrient)
  
  This particular BSA is specifically evaluated and tested to have very low protease content / for protease-free status. Protease-free BSA may be used in applications like:
  
  • Enzyme assays
  • Protein-based assays
  • Protease-sensitive techniques that include:
  a) Enzyme immunoassay (EIA)
  b) Nucleic acid hybridization
  c) Radioimmunoassay (RIA)

• 生物活性

  Bovine Serum Albumin is a BSA (bovine serum albumin) is a widely used blocking reagent for use in immunohistochemistry (IHC), Immunocytochemistry (ICC), ELISAs and Western blotting. Used to block non-specific binding of antibodies. Can also be used as a protein concentration standard in Bradford assay for protein quantification. BSA is also used in cell culture.
