Convenient and effective method for removing fibrinogen from serum specimens before protein electrophoresis.
BACKGROUND Fibrinogen in serum specimens can be misinterpreted on protein electrophoresis as a monoclonal protein. We evaluated selective precipitation of fibrinogen with ethanol. METHODS Pooled human plasma was mixed with absolute ethanol or saline (final concentrations of 40, 80, 100, 120, and 160 mL/L) and incubated at 4 degrees C overnight or placed in an ice bath for 15 min. After centri...
متن کاملThe effect of fibrin-stabilizing factor on the subunit structure of human fibrin.
The formation of human fibrin from fibrinogen has been examined by polyacrylamide gel electrophoresis in sodium dodecyl sulfate, a method which separates a mixture of proteins on the basis of differences in molecular weight. It has been found that the plasma from a patient with a congenital deficiency of fibrin-stabilizing factor forms clots lacking the cross links among the alpha- and gammacha...
متن کاملHuman platelet fibrinogen: purification and hemostatic properties.
Conditions were developed in which 80% to 90% of platelet fibrinogen could be routinely purified in nondegraded form from the fluid phase of platelet suspensions stimulated with the calcium ionophore, A23187, in the presence of calcium, leupeptin, and prostaglandin E1. Fibrinogen was separated from other released proteins by chromatography on diethylaminoethanol (DEAE)-cellulose using a continu...
متن کاملHuman plasma derived drugs separation by fractionation of plasma with polyethylene glycol
Background: There are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. There are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. Ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...
متن کاملFibrinogen biosynthesis in isolated guinea pig megakaryocytes.
Fibrinogen synthesis was investigated in guinea pig megakaryocytes. Purified megakaryocytes were incubated with 35S-methionine in methionine-free incubation medium for 18 hours. Newly synthesized fibrinogen in megakaryocyte lysates enriched with purified carrier guinea pig fibrinogen was immunoprecipitated with a specific anti-guinea pig fibrinogen antiserum produced in rabbits. Proteins in the...
