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.</p>
