Leírás

Alkalmazás

Select the right albumin for your application with the Albumin Selection Guide.

A non-acetylated protein suitable as a blocking agent in Southern blotting. If your application requires nuclease-free BSA, we recommend our acetylated BSA for these critical applications.

Biokémiai/fiziológiai hatások

Certain conformational and primary-sequence epitopes of BSA are suspected allergens in human beef and milk allergies.

Tulajdonságok és előnyök

• Protease free
• Suitable for blocking non-specific protein binding sites in hybridizations
• Heat shock fractionated

Elkészítési megjegyzés

Prepared using heat shock fractionation

Serum albumin may be referred to as Fraction V. This naming convention is taken from the original Cohn method of fractionating serum proteins using cold ethanol precipitation. Serum albumin was found in the fifth ethanol fraction using Cohn′s method. Since then, the term "Fraction V" has been used by some to describe serum albumin regardless of the method of preparation. Others have used this term to describe serum albumin purified by ethanol fractionation methods that have been highly modified since the original Cohn method was described. Sigma-Aldrich manufactures and distributes serum albumins purified from a variety of primary methods including the true Cohn fractionation method, modified ethanol fractionation methods, heat shock and chromatography. Additional purification steps may include crystallization or charcoal filtration.
