IgM
IgM are immunogloublins secreted upon the body's first contact with an antigen. They are the first type of immunoglobuilins released by plasmocytes. The presence of IgM in the blood indicates…

cation exchange of plasma proteins
Conditions/Parameters for CEX Bind and Elute Mode: If a CEX is used at pH 6.5-6.6, IgG binds to the resin whereas negatively charged protein fraction is unbound. An almost pure…
anion exchange of plasma proteins
Anion Exchange Almost pure IgG can be isolated in one step by AEX on DEAE ion exchangers at pH 6.5-6.6. Under these conditions, about 90% of the plasma proteins are…
chromatography
In the 1970s, chromatography was also found to be useful in the separation and purification of plasma proteins, particularly for the final purification of gamma globulin after separation from the…
ethanol fractionation
In General: Separation of Immune globuline (IgG) from blood plasma depends upon the early work by Edwin J. Cohn which is based on cold ethanol fractionation which co-precipitates groups of proteins based…
