A practical proposal for arginine-vasopressin radioimmunoassay. 1978

M A Moulin, and R Camsonne, and M C Bigot, and D Debruyne

This work proposes the use of (a) a commercially available homologous system AVP antibody-AVP (Arginine Vasopressin) standard and (b) new acquisitions for the improvement of sensitivity for AVP radioimmunoassay by separate or simultaneous use of two-phase sequential incubation and epsilon-aminocaproic acid (EACA). The antiserum used in the system described is very specific since none even cross-reacted with lysine vasopressin (LVP) and has an apparent affinity constant (K) of 0.909 +/- 0.047 X 10(12) l/mol. This is sufficiently high to detect 0.5 +/- 0.2 pg/tube, which is theoretically expected of biological AVP. The total assay time is less than 48 h.

UI	MeSH Term	Description	Entries
D007457	Iodine Radioisotopes	Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes.	Radioisotopes, Iodine
D008722	Methods	A series of steps taken in order to conduct research.	Techniques,Methodological Studies,Methodological Study,Procedures,Studies, Methodological,Study, Methodological,Method,Procedure,Technique
D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.

D001984	Bronchial Neoplasms	Tumors or cancer of the BRONCHI.	Neoplasms, Bronchial,Bronchial Neoplasm,Neoplasm, Bronchial
D002606	Charcoal	An amorphous form of carbon prepared from the incomplete combustion of animal or vegetable matter, e.g., wood. The activated form of charcoal is used in the treatment of poisoning.

D000918	Antibody Specificity	The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.	Antibody Specificities,Specificities, Antibody,Specificity, Antibody
D001127	Arginine Vasopressin	The predominant form of mammalian antidiuretic hormone. It is a nonapeptide containing an ARGININE at residue 8 and two disulfide-linked cysteines at residues of 1 and 6. Arg-vasopressin is used to treat DIABETES INSIPIDUS or to improve vasomotor tone and BLOOD PRESSURE.	Argipressin,Vasopressin, Arginine,Arg-Vasopressin,Argipressin Tannate,Arg Vasopressin
