Albumins are readily soluble in water and can only be precipitated by high concentrations of neutral salts such as ammonium sulfate.

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. We 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.

Application:
It is suitable for use as an enzyme stabilizer during purification or for dilution of restriction endonucleases and nucleic acid modifying enzymes. 
BSA is also commonly used in DNA and protein labeling experiments as a blocking agent to minimize background.

 

Storage
Please store at 4°C. Protect from moisture and light. Keep dry.

Note：
Open the bottle after it return to room temperature to avoid moisture.

Albumins are readily soluble in water and can only be precipitated by high concentrations of neutral salts such as ammonium sulfate. The solution stability of BSA is very good (especially if the solutions are stored asfrozenaliquots). Infact,albuminsarefrequentlyusedasstabilizersforothersolubilizedproteins(e.g., labile enzymes). However, albumin is readily coagulated by heat. When heated to 50°C or above, albumin quite rapidly forms hydrophobic aggregates which do not revert to monomers upon cooling. At somewhat lower temperatures aggregation is also expected to occur, but at relatively slower rates.
