Latex for immobilizing biologically active substances

Abstract

Abstract Polymer particles dispersible to form a latex and latices of such polymer particles, said particles being adaptable to the fixing or bonding thereto of a biologically active substance and having a core-shell construction wherein the polymer material of the core determines the stability of the form of the latex particles and their redispersibility, and the material of the shell (1) is so hydrophilic that it would be completely or largely water soluble if it were not anchored to the core material and/or crosslinked, (2) contains functional groups which are suitable for the covalent fixation or bonding of biological active substances, and (3) in an anhydrous condition has a T lambda max from 20 DEG -250 DEG C., depending on its composition, and methods for bonding a biologically active substance to such particles, for example to prepare a diagnostic reagent.
