摘要:
The present invention relates to the diagnosis of HIV infections. It especially teaches the production of a soluble retroviral surface glycoprotein- (or transmembrane glycoprotein)- chaperone complex and the advantageous use of a chaperone-antigen complex especially in the detection of antibodies to HIV in immunoassays, preferably according to the double antigen bridge concept, or as an immunogen. The invention also discloses soluble complexes comprising a variant of HIV-1 gp41 or a variant of HIV-2 gp36, respectively, and a chaperone selected from the peptidyl-prolyl-isomerase class of chaperones. Variants comprising specific amino-acid substitutions in the N-helical domain of HIV-1 gp41 or of HIV-2 gp36, respectively are also described.

摘要:
The present disclosure describes a method for predicting the risk of a patient to suffer from acute kidney injury (AKI) during or after a surgical procedure or after administration of a contrast medium. The method is based on the determination of the level of the biomarker IGFBP7 (Insulin-like Growth Factor Binding Protein 7) in a body fluid sample obtained from the patient prior to the surgical procedure or prior to the administration of a contrast medium. Further, the present disclosure describes a method for predicting the risk of a patient to suffer from acute kidney injury (AKI) based on the determination of the amount of the biomarker IGFBP7 (Insulin-like Growth Factor Binding Protein 7) and Cystatin C in a body fluid sample obtained from the patient. The present disclosure further encompasses kits and devices adapted to carry out the methods of the disclosed methods.
摘要:
The present disclosure relates to a recombinant immunoglobulin heavy chain comprising a VH-domain a CH1 domain a hinge region down to the C-terminal most cysteine of the middle hinge region, a sortase conjugation loop, a CH2 domain and a CH3 domain, wherein the sortase conjugation loop a) consists of at least 16 amino acids located between the C-terminal most cysteine of the middle hinge region and the VFX1FPP (SEQ ID NO: 2; wherein X1 is L or I) consensus sequence at the N-terminus of an immunoglobulin heavy chain CH2-domain, b) comprises a sortase recognition motif consisting of the amino acid sequence LPX1TX2 (SEQ ID NO: 01), wherein X1 can be any amino acid residue and X2 is G or A, c) comprises N-terminal to the sequence of (b) at least two amino acids, d) comprises C-terminal to the sequence of (b) at least 6 amino acids, and e) wherein the amino acids C- and N-terminal to the sequence of (b) are not cysteine and its use in site-directed conjugation based on the enzyme sortase.
