Antibody Labeling

Hot Products

Our antibody labeling collection offers various ways for primary antibody labeling. The antibody labeling chemistry we provide involves either free amine groups or free sulfhydryl groups. Direct antibody conjugation enables the labeled antibody to be used in further immunoassay analyses. We provide different kinds of conjugation detection methods as follows:

Biotin/Streptavidin: Avidin, Biotin, Streptavidin
Enzyme: AP, Glucose oxidase, HRP
Fluorophore: AMCA, FITC, PE, PerCP, Rhodamine
Tandem: Texas Red or Atto594 combined with PE
Lanthanide: Europium

With the variety of labels we provide, conjugated antibodies may further be applied to the immunoassays listed in the table below:

Immunoassay	Labels
Western Blot	Enzyme (usually HRP or AP)
ELISA	Enzyme, Biotin/Streptavidin
Immunofluorescence	Fluorescent dyes
Immunohistochemistry	Enzyme, Biotin/Streptavidin
Fluorescence Technology	Fluorescent dyes, Tandem dyes, Lanthanide
