Sigma-Aldrich offers a large portfolio of conjugated antibodies. A conjugated antibody is a monoclonal or polyclonal antibody linked to a label and used for detection in a diverse range of assay techniques. Sigma-Aldrich offers conjugated antibodies linked to a variety of colorimetric and fluorescent labels for use in detection, purification, sorting, and microscopy applications. Commonly used conjugated antibodies utilize enzymes such as horseradish peroxidase and alkaline phosphatase for colorimetric detection, or fluorescent molecules including fluorescein isothiocyanate (FITC), tetramethylrhodamine isothiocyanate (TRITC), cyanine (Cy3), or phycoerythrin (R-PE). Conjugated antibodies are produced in a variety of host animals making them compatible with a broad range of immunochemical reagents. For those users whose research requires labeling their own reagents, Sigma-Aldrich offers antibody labeling kits
for the conjugation of various labels (biotin, FITC, CF™
) to monoclonal and polyclonal antibodies.
Each of our conjugated antibodies is covered by our Bioguarantee
so that you can evaluate our antibodies with complete peace of mind.
