FITC-BSA conjugate


The antibody reacts with both free and conjugated fluorescein isothiocyanate (FITC).

Physical form

Solution in 0.05 M Tris buffer, pH 8.0, containing 1% bovine serum albumin, 50% glycerol, 1 mM MgCl2 and 15 mM sodium azide


Alkaline phosphatase-conjugated mouse anti-FITC antibody was used for immunohistochemistry on mouse spleens. Tissue sections were fixed in acetone, blocked with PBS/5% goat serum/ 0.1% Tween and incubated with a FITC-conjugated primary antibody prior to the addition of the AP-conjugated anti-FITC antibody.

Antibodies to FITC serve as universal indicator reagents by bridging FITC with another immunohistochemical reagent such as alkaline phosphatase or horseradish peroxidase. Mouse monoclonal clone FL-D6 anti-FITC−Alkaline Phosphatase conjugate antibody may be used for the detection of FITC and as a universal indicator reagent for bridging FITC with other immunochemical reagents. It can be used in ELISA and immunofluorescent techniques.

General description

FITC (fluorescein isothiocyanate) is a fluorochrome dye that absorbs ultraviolet or blue light causing molecules to become excited and emit a visible yellow-green light. This emission ceases upon removal of the light causing the excitation. Fluorochrome labeling provides rapid, accurate localization of antigen-antibody interaction when one of the reactants is part of a cell, tissue or other biological structure. FITC is a commonly used marker for antibodies in immunofluorescent techniques because the conjugation of FITC to proteins is relatively easy and generally does not destroy the biological activity of the labeled protein. FITC is widely used as a hapten to label different proteins. Antibodies to FITC are used to identify FITC labeled proteins and as models to study the mechanism of antibody response to a well defined hapten.

Mouse monoclonal clone FL-D6 anti-FITC−Alkaline Phosphatase conjugate antibody reacts with either free or conjugated FITC. The antibody does not react with bound or free TRITC (tetramethylrhodamine isothiocyanate). Monoclonal Anti-FITC recognizes the free FITC molecule and FITC conjugated to various biomolecules such as proteins (immunoglobulins, enzymes), oligonucleotides, nucleic acids and other ligands.
