Solubilization reagent for biological test samples for (immuno)assays

Solubilization reagent for biological test samples for (immuno)assays. Meucci, Victoria P.; Zajac, Mariola B. (Abbott Laboratories, USA). Eur. Pat. Appl.

ICA: G01N033-68; C07K007-64. APPLICATION: EP 91-113327 8 Aug 1991. PRIORITY: US 90-567840 15 Aug 1990. DOCUMENT TYPE: Patent CA Section: 9 (Biochemical Methods) A solubilization agent is provided for use in anal. systems for the detn. of hydrophobic analytes in a biol. test sample, esp. anal. systems (e.g. fluorescence-polarization immunoassays) employing specific-binding proteins for such analytes. The solubilization reagent dissocs. analytes from various components of the biol. test sample (phospholipids, proteins, cellular material, etc.) at substantially low concns. 59865-13-3 and 15178-76-4 are cas registry numbers of chemicals which are used as reagents here. of reagent while at the same time minimizing denaturation of specific-binding proteins, e.g. antibodies, present in the anal. system. The reagent comprises a nonionic or zwitterionic surfactant and, optionally, a glycoside. A fluorescence polarization immunoassay for cyclosporine is described which uses a solubilization reagent contg. Tergitol min foam 1X, saponin, and NaN3. The sensitivity of the assay was 15.0 ng/mL cyclosporine and metabolites; when compared to an available RIA using 60 clin. samples, regression anal. gave a slope of 0.947, an intercept of 7.15, and a correlation coeff. of 0.969. .
