General description

BSA is a known carrier of fatty acids (FA). Thus control over the specific FA′s for culture of cell lines is important, as different cell lines can be differentially sensitive to particular fatty acids. Fatty acid-free BSA thus is a useful tool for cell culture experiments where the specific fatty acid content must be tightly controlled, to allow researchers to use particular fatty acids specific to their cell lines. Fatty acid-free albumin also allows for optimal and maximum binding sites for adding specific fatty acids to use in cell culture. The use of FA-free BSA also mitigates concerns about endogenous FA′s potentially in non-FA-free BSA.
Bovine serum albumin (BSA) is a highly abundant plasma protein that assists in the regulation of the colloidal osmotic pressure of blood. BSA is used in many different applications, such as cell culture, immunochemistry, and protein quantitation.

This BSA product is specifically tested for very low FA content / fatty acid free status.

Biochem/physiol Actions

Se sospecha que ciertos epítopos conformacionales y de secuencia primaria son alérgenos en las alergias humanas a la leche y a la carne.

Features and Benefits

  • Cold ethanol fractionated
  • Essentially fatty acid-free

Preparation Note

La seroalbúmina puede denominarse también Fracción V. Esta convención de nomenclatura procede del método original de fraccionamiento de las proteínas séricas de Cohn en el que se utiliza precipitación en etanol frío. Utilizando dicho método, la seroalbúmina se encontró en la fracción quinta del etanol. Desde entonces, algunos han venido utilizando la expresión «Fracción V» para describir la albúmina sérica, al margen del método de preparación. Otros han utilizado este término para describir la seroalbúmina purificada por métodos de fraccionamiento en etanol que se han modificado mucho desde que se describió el método Cohn original. Sigma-Aldrich fabrica y distribuye seroalbúminas purificadas mediante una variedad de métodos primarios, entre ellos el verdadero método de fraccionamiento de Cohn, los métodos de fraccionamiento en etanol modificados, el fraccionamiento térmico y la cromatografía. Etapas de purificación añadidas pueden ser la cristalización o la filtración en carbón activado.
Often referred to as Cohn fraction V; this product is prepared by a modified method of the Cohn cold ethanol fractionation method.
