General description

Estapor® standard polystyrene microspheres offer a simple and convenient option for the development of a wide range Latex Turbidimetry Immunoassay (LTIA) diagnostic tests. The plain surface of the microsphere is designed to be easily and quickly coated with the antibody or antigen of choice via protein adsorption through hydrophobic and ionic interactions. The simplicity of this conjugation process is a key feature of these microspheres and has attracted many diagnostic test developers whom have successfully utilized these microspheres for several years in a wide variety of LTIAs.

Application

Main applications of the standard microspheres include nephelemetric assays, immune-turbidimetric assays, latex agglutination tests, solid phase immunoassays, microspheres capture ELISA, calibration
