Human 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 کاملRecombinant Ganoderma lucidum immunomodulatory protein modified with polyethylene glycol.
Recombinant Ganoderma lucidum immunomodu-latory protein (rLZ-8) expressed using the Pichia yeast eukaryotic expression system is a potential new drug for cancer therapy; however, it has a short half-life in the body. In order to optimize the potency and stability of rLZ-8, we modified the recombinant protein chemically using methoxy-PEG-succinimid...
متن کاملSize fractionation of double-stranded DNA by precipitation with polyethylene glycol.
We show that DNA molecules of differing molecular mass are separable by selective precipitation with polyethylene glycol (PEG+.. Higher molecular mass DNA precipitates at lower PEG concentrations than lower molecular mass DNA. Double-stranded DNA can be fractionated at least in the range of 3 times 10-7 to 1 times 10-5 daltons. The effects on PEG concentration, sodium chloride concentration, DN...
متن کاملHuman Plasma Derived Drugs Separation by Fractionation of Plasma with Polyethylene Glycol
Human blood as a unique tissue (1), contains many important proteins with therapeutic uses (2). As a biological drugs, virus inactivation is one of the crucial steps in their preparations of these plasma derived proteins (3-6). The most important proteins in human plasma are: albumin, immunoglobulin, fibrinogen, and coagulation factors VII, VIII and IX (7). There are varieties of purification t...
