Convenient assay for interferons.
A convenient assay for interferons based on reduction of cytopathic effect was developed. The number of manipulations and the lengths of the various incubation steps were reduced to a minimum. The assay is simple to perform and can be completed within 16 h. Moreover, it can be used with various types of cells and a variety of viruses.
متن کاملConvenient biological assay for polyethylene glycol-interferons in patients with hepatitis C.
The vesicular stomatitis virus cytopathic effect reduction assay is suitable to quantify polyethylene glycol-alpha interferon 2a (PEG-IFN-alpha 2a) and PEG-IFN-alpha 2b. Human serum and ribavirin did not interfere with the assay. This bioassay was successfully used for assaying PEG-IFN-alpha 2a and PEG-IFN-alpha 2b in serum samples from patients undergoing combination therapy.
متن کاملRapid and convenient method for the assay of aminopropyltransferases.
A new method for the assay of aminopropyltransferase activity is described. The method measures the formation of [methyl-14C]methylthioadenosine from decarboxylated S-adenosyl[methyl-14C]methionine in the presence of an amine acceptor. When used with extracts from rat ventral prostate, kidney, liver or brain, and with putrescine or spermidine as amines, the method gave results in excellent agre...
متن کاملA convenient assay of glycoserum by nitroblue tetrazolium with iodoacetamide.
BACKGROUND To determine glycoserum, the nitroblue tetrazolium (NBT) assay is quick, economical, convenient and easily automated. This method, however, is vulnerable to interference by thiol group, which should not be ignored during the analysis. METHODS Thiol group in glycoserum was blocked with iodoacetamide (IAM) before NBT was added. The reaction was carried out in a thermal bath and termi...
متن کاملInterferons
nterferons, naturally occuring glycoproteins with molecular weights of approximately 20,000 daltons, possess antiviral, antiproliferative, and immune-stimulating properties. They are classified into 3 antigenically distinct forms that are derived from different cell types. Alpha (or) interferons are derived from leukocytes, beta ([3) interferons from fibroblasts, and gamma (/) interferons from ...
