Descrizione generale
Bovine Serum Albumin (BSA) is a plasma protein produced in the bovine liver that has a globular, non-glycosylated α-helical structure. It consists of a single polypeptide chain with 583 amino acid residues and 17 cysteine residues that form the cross-linked disulfide bridges, stabilizing its structure. The BSA protein comprises three structurally distinct domains (I, II, and III), each of which contains two sub-domains (A and B) arranged in a heart-shaped architecture.
Applicazioni
Bovine Serum Albumin (BSA) has been used
- as a component of phosphate buffer saline (PBS) solution for dissolving tumor necrosis factor α (TNFα), which was added as a supplement for culture media
- as a blocking agent to reduce non-specific binding during the albumin sensor assay
- as a blocking agent in the immunofluorescence (IF) assay
- as a protein standard in the Bradford assay
Azioni biochim/fisiol
Si sospetta che alcuni epitopi conformazionali e di sequenza primaria di BSA siano allergeni nelle allergie umane a carne bovina e latte.
Bovine Serum Albumin (BSA) is a versatile protein commonly utilized in cell and tissue culture media as a supplement. It helps in lipid solubilization and stabilizing other proteins. BSA is also a carrier for small molecules such as steroids, fatty acids, and thyroid hormones. It serves as a standard protein for immunochemical tests to determine protein concentration in a solution and calibration studies.

Nota sulla preparazione
Ci si riferisce alla sieroalbumina come Frazione V. Questa designazione è presa dal metodo originale introdotto da Cohn per frazionare siero proteine usando la precipitazione in etanolo a freddo. La sieroalbumina è stata trovata da Cohn nella quinta frazione col suo metodo basato sull′etanolo. Da allora il termine “Frazione V” è stato usato da alcuni a prescindere dal metodo di preparazione. Altri hanno usato questa terminologia riferita a sieroalbumina purificata con metodi di frazionamento basati su etanolo che sono stati profondamente modificati dai tempi in cui Cohn li ha descritti. Sigma-Aldrich produce e distribuisce sieroalbumine purificate con vari metodi primari inclusi il metodo originale di frazionamento di Cohn, metodi modificati di frazionamento con etanolo, shock termico e cromatografia. Stadi successivi di purificazione possono comprendere cristallizzazione o filtrazione su carbone attivo.
