Descrizione

General description

Bovine Serum Albumin (BSA) is a globular protein derived from bovine blood plasma. It is widely utilized as a standard in protein quantitation assays due to its stability and lack of interference with the assay components.​

The USP BSA for Protein Quantitation standard serves as a calibration reference in assays such as the Bradford and Bicinchoninic Acid (BCA) assays, ensuring accurate and reproducible measurement of protein concentrations in various research and clinical applications.

The USP biologics proteins category provides critical standards and reference materials necessary for the development and manufacturing of therapeutic proteins. These proteins, which can be naturally derived or genetically engineered, are essential in treating various diseases and conditions, ensuring that they meet quality, safety, and efficacy standards.

The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.

Application

BSA for protein quantitation USP reference standard in specified compendial tests and assays.

Also used to prepare standard and suitability standard solutions during the determination of total protein in pharmaceutical drug substances and products according to the United States Pharmacopeia (USP) general chapter.

Biochem/physiol Actions

Si sospetta che alcuni epitopi conformazionali e di sequenza primaria di BSA siano allergeni nelle allergie umane a carne bovina e latte.

Preparation Note

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.
