摘要:
This invention relates to anti-P-selectin antibodies and, in particular, to anti-P-selectin antibodies and variants thereof that contain an Fc part derived from human origin and do not bind complement factor C1q. These antibodies have new and inventive properties causing a benefit for a patient suffering from critical limb ischemia or peripheral arterial occlusive disease (CLI/PAOD).

摘要:
A method for the recombinant production of a polypeptide by expressing a nucleic acid encoding said polypeptide in a microbial host cell, forming in the cytoplasm of said host cell inclusion bodies containing said polypeptide, and isolating, solubilizing and naturing said polypeptide, characterized in that after fermentation the host cell or the host cell content is incubated at a temperature of 40° C. or higher for at least 10 minutes and subsequently insoluble polypeptide is isolated from the host cell, this method providing an improved yield in inclusion bodies containing the desired polypeptide.
摘要:
The present invention concerns muteins of avidin and streptavidin with a reduced binding affinity for biotin as well as their use as interference elimination reagents in methods for the determination of an analyte e.g. in diagnostic tests such as for example immunoassays and nucleic acid hybridization assays. In addition the invention concerns the use of muteins of avidin and streptavidin as systems capable of regeneration for binding biotin e.g. for the analysis of biotinylated molecules, for examining receptor ligand interactions as well as for the affinity purification of biotinylated molecules.
摘要:
The invention relates to a process for recombinant preparation of peptides by expression of a DNA in micro-organisms, which DNA codes for a fusion protein made of streptavidin and one of the said peptides. Streptavidin and the peptide are bound by a peptide sequence which can be cleaved by an endoproteinase. The process also includes isolation of the insoluble, inactive protein, solublisation of the inactive protein using a denaturant, dilution of the denaturant at a pH value of between 8.5 and 11 until cleaving of the fusion protein by an endoproteinase can take place, cleaving of the fusion protein, lowering of the pH value until streptavin and non-cleaved fusion protein precipitate, and cleaning of the desired peptide from the supernatant. Said process is particularly suitably for producing parathromone and urodilatin and fragments thereof.
