PDE3A Antibody BIOTIN

The Avidin-Biotin Complex (ABC) Method and Other Avidin-Biotin Binding Methods

These methods involve, at their core, the vitamin biotin and the protein avidin, which bind together irreversibly. By establishing a biotin link, through avidin, between the horseradish peroxidase enzyme and a secondary antibody reagent

The Avidin-Biotin Complex(ABC) Method

, between the horseradish peroxidase enzyme and a secondary antibody reagent, enzyme localization can be achieved at the site of primary antibody interaction with the specimen (see ) Fig. 1 ). The biotin molecule is small and can be easily conjugated to immunoglobulin

sample to 1 mg/ml (or less). Prepare 1 mg/ml solution of NHS-Biotin in DMSO. Add NHS-Biotin in DMSO to antibody at desired ratio e.g. for 1:8 ratio add 125 ml of NHS-Biotin to 1mg of Ab Incubate on rotator for 4 hours at room
