Method for the determination of HIV antibodies

The method operates on the principle of the heterogenous immunoassay and is characterised in that the sample is incubated simultaneously or sequentially in a reaction vessel to whose internal surface streptavidin is bound in an amount such that 0.1 - 2.5 mu g are present per ml of reaction volume a...

Zusammenfassung:	The method operates on the principle of the heterogenous immunoassay and is characterised in that the sample is incubated simultaneously or sequentially in a reaction vessel to whose internal surface streptavidin is bound in an amount such that 0.1 - 2.5 mu g are present per ml of reaction volume a) with at least one biotinylated polypeptide which consists of a maximum of 50 amino-acid residues and contains the amino acid sequence CAFRQVC and/or CSGKLIC, where in each case the two cysteines (C) of the two amino-acid sequences are cyclised to cystine bridges, and the polypeptide is monomeric, b) and with a labelled receptor which is directed against HIV antibodies, the liquid and solid phases are separated and the label in one of the two phases is determined as a measure of the HIV antibody.
