Preparation Note
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.

Application
Thiopropyl Sepharose® 6B is used in protein chromatography, affinity chromatography and hydrophobic interactions. Thiopropyl Sepharose® 6B has been used for the removal of inhibitors from PCR extracts from evidence collected for law enforcement murder investigations. Thiopropyl Sepharose® 6B has also been used to describe a method for the investigation of functional properties of distinct domains of viral thiol proteins, including the influenza virus membrane M1 protein.
