摘要:
A fusion protein with at least one antigenic and/or immunogenic determinant from the env, gag and/or pol region of HIV1 and/or HIV2 which contains the tetrapeptide sequence NH.sub.2 -Met-Tyr-Tyr-Leu as the N-terminal component as well as a process for its production and use.
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).

Antibodies against insulin like growth factor I receptor (IGF-IR), methods for their production, pharmaceutical compositions containing said antibodies, and uses for such antibodies are disclosed. Such antibodies are implicated in antitumor therapy.
摘要:
Antibodies which bind to IGF-IR and inhibit the binding of IGF-I and IGF-II to IGF-IR are characterized. These antibodies are implicated in anti-tumor therapy.
摘要:
A method for the recombinant production of a heterologous polypeptide in a eukaryotic host cell is described. The host cell comprises an expression plasmid, whereby the expression plasmid comprises in a 5′ to 3′ direction a) a promoter, b) a nucleic acid encoding a first polypeptide, whose amino acid sequence is selected from Table 1 depending on the first two amino acids of the second polypeptide, c) a nucleic acid encoding a second polypeptide comprising a nucleic acid encoding a heterologous polypeptide, a nucleic acid encoding a linker, and a nucleic acid encoding an immunoglobulin fragment, and d) a 3′ untranslated region comprising a polyadenylation signal. Further a plasmid and a kit are described.
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:
A chimeric serine protease whose protease domain is composed of two domain halves (half-sides) with a &bgr;-folded sheet structure, wherein the first domain half corresponds to the first domain half of a first serine protease and the second domain half corresponds to the second domain half of a second serine protease, has improved properties and can be readily crystallized.
摘要:
Saccharomyces mutants with defects in N-glycosylation which are obtainable by �.sup.3 H!-mannose suicide selection, introduction of one or several selective markers, selection of those strains which, after transformation with the plasmid YEpL/glucose oxidase, secrete 10 mg/l GOD or more into the culture medium after culture under standard conditions, are allelic to the ngd mutations in Saccharomyces cerevisiae, DSM 7042, DSM 7338, DSM 7160 and/or 7340 and express proteins with a uniform carbohydrate structure.
摘要:
Herein are reported glycosylated repeat-motif-molecule conjugate of the following formula: (repeat-motif-molecule−linkern)m−conjugation partner−(linkero−repeat-motif-molecule)p, wherein n and o are independently of each other and independently for each value of m and p integer values of 0 or 1, and m and p are independently of each other integer values of 0 or 1 or 2 or 3 or 4 or 5 or 6 or 7, and wherein the repeat-motif-molecule conjugate comprises at least one oligosaccharide attached to a glycosylation site. Also reported are encoding nucleic acids and method for producing these repeat-motif-conjugates in mammalian cells.
摘要:
A pro-polypeptide which is useful for the expression of a polypeptide of interest in a prokaryotic cell. Therefore the pro-polypeptide is fused to the N-terminus of the polypeptide of interest. The pro-polypeptide as reported herein provides for improved expression yields and improves the handling of the fusion polypeptide (downstream processing, purification). For example, efficient endotoxin removal is effected while the protein of interest comprising the pro-polypeptide is bound e.g. to an affinity chromatography material. Thereafter the pro-polypeptide can efficiently be cleaved from the polypeptide of interest by the incorporated protease cleavage site with the cognate protease.
