摘要:
Asn-linked glycoprotein which has a molecular weight of 32 - 84 kDa, absorbs to Concanavalin A and has antitumour activity, a mixture of such glycoproteins, a microorganism which produces the glycoprotein or mixture. The glycoprotein and mixture can be produced by culturing a microorganism belonging to the genus Aspergillus and isolating the glycoprotein or mixture. The glycoprotein is effective for treatment of solid tumor, ascites tumor, multiple cytoma and oral tumor, and for the suppression of tumors.
摘要:
A method for electrophoresis of nucleic acid fragments present in the solution which contains an amount, e.g., 0.2 % or more, of a reagent, e.g., glycerol, dithiolthreitol (DTT) and trehalose or other sugars, which interact to form a complex with borate or boric acid. The method includes applying the solution to an electrophoretic gel and electrophoresing those fragments into the gel in the presence of a buffer lacking boric acid, or a derivative thereof, which forms a chelate complex with the reagent and thereby causes distortion of electrophoresis of the fragments in a gel including such a buffer.
摘要:
Porous substrates comprising acrylonitrile polymer or copolymer cores and a hydrolyzed surface, with low conversion to amide groups and substantially no formation of imide or carboxyl groups on said surface. The substrates and functionalized derivatives thereof, are useful in highly selective chromatographic separations.
摘要:
The present invention relates to monoclonal antibodies to purified recombinant HCV envelope proteins. During isolation of the recombinantly expressed protein a disulphide bond cleavage or reduction step is carried out with a disulphide bond cleavage agent; this is followed by a step preventing reformation of disulphide bridges. The present invention also relates to the diagnostic and therapeutic application of these monoclonal antibodies.
摘要:
The present invention relates to a method for purifying recombinant HCV single or specific oligomeric envelope proteins selected from the group consisting of E1 and/or E2 and/or E1/E2, characterized in that upon lysing the transformed host cells to isolate the recombinantly expressed protein a disulphide bond cleavage or reduction step is carried out with a disulphide bond cleavage agent. The present invention also relates to a composition isolated by such a method. The present invention also relates to the diagnostic and therapeutic application of these compositions. Furthermore, the invention relates to the use of HCV E1 protein and peptides for prognosing and monitoring the clinical effectiveness and/or clinical outcome of HCV treatment.
摘要:
The present invention relates to a recombinant vectors encoding an HCV envelope E1 and/or E2 and/or E1/E2 protein encoding sequence. The invention also relates to recombinant nucleic acids comprising said HCV protein encoding sequences. The invention further relates to host cells transformed with said recombinant vectors, as well as recombinant HCV proteins expressed by said host cells and use thereof in diagnostic methods or kits or therapeutic or prophylactic methods of treatment of HCV or HCV vaccine compositions.
