The invention provides a dry immunofluorescence quantitative method heparin binding protein (HBP) detection kit. The kit comprises a reagent strip, the reagent strip comprises absorbent paper, a nitrocellulose membrane and a sample pad, the absorbent paper is located at one end of the nitrocellulose membrane, the sample pad is located at the other end of the nitrocellulose membrane, and the nitrocellulose membrane is sequentially coated with a quality control C line, a detection T line and a fluorescent antibody solidus; a novel fluorescence labeling process, a sample pad treating fluid and afluorescence marker immobilization process are adopted to rapidly, accurately and quantitatively detect heparin binding protein HBP in human plasma with high sensitivity, so that the problems that labeled fluorescent substances are unstable and later process control is not facilitated are solved; meanwhile, the fluorescent antibody is immobilized on the nitrocellulose membrane instead of a specialfluorescent binding pad, so that the precision is remarkably improved on the basis of widening the storage conditions of the kit.

Provided is a reagent for assaying a thrombin-antithrombin complex (TAT) in a blood sample from a subject by latex agglutination assay. The reagent includes a polycation. As a result, TAT complexes can be precisely assayed while circumventing the effect of heparin. The polycation is, for example, hexadimethrine bromide, chitosans, modified dextran, aminodextran, hydroxymethyl cellulose trimethylamine, lysozyme, spermine, spermidine, polylysine, polyarginine, polyornithine, protamine sulfate, hydroxyethyl cellulose trimethylamine, heparin-binding protein, polyallylamine, polyallylamine hydrochloride, poly(diallyl dialkyl amine), polyamideamine, polyamine, polyvinylbenzyltrimethylammonium chloride, polydiallyldimethylammonium chloride, polyethyleneimine, polypropyleneimine, polypropylethyleneimine, polyimidazoline, polyvinylamine, polyvinyl pyridine, poly(acrylamide/methacryloxypropyltrimethylammonium bromide), poly(diaryldimethylammonium chloride/N-isopropylacrylamide), poly(dimethylaminoethyl acrylate/acrylamide), poly(dimethylaminoethyl methacrylate), polydimethylaminoepichlorohydrin, polyethyleneiminoepichlorohydrin, polymethacryloxyethyl-trimethylammonium bromide, hydroxypropylmethacryloyloxyethyl dimethyl ammonium chloride, poly(methyldiethylaminoethylmethacrylate/acrylamide), poly(methyl/guanidine), polymethylvinylpyridinium bromide, poly(vinylpyrrolidone-dimethylaminoethyl methacrylate), or polyvinylmethylpyridinium bromide.
