Tus neeg sawv cev sulfoNHS acetate acetate (sulfosuccinimide acetate) yog dej soluble.Sulfo-NHS acetate irreversibly reacts nrog thiab thaiv cov thawj amines ntawm pH ntau dua 7, xws li nyob rau hauv lysine, los tsim acylated cov ntaub ntawv.Kev siv sulfo-NHS acetate tiv thaiv polymerization thaum ua cov protein sib txuas cov kev sib txuas.Lwm qhov kev siv ntawm sulfoNHS acetate suav nrog kev tiv thaiv polymerization thaum sib txuas cov hapten peptides nrog cov cab kuj los tsim cov tshuaj tiv thaiv kab mob.
Siv: Kev txiav txim siab ntawm chromogenic substrates rau phosphatase;nrhiav kom tau chromogenic substrates rau acidic thiab alkaline phosphatase;cov tshuaj tiv thaiv tuaj yeem tsim cov khoom lag luam daj, uas tuaj yeem nyeem tau ntawm lub wavelength ntawm 405nm, thiab cov tshuaj tiv thaiv tuaj yeem kuaj pom los ntawm 3 N NaOH kev daws teeb meem.
