Epitope Tag Antibodies

Epitope tags are short sequences that can be attached to a molecule of interest by using chemical conjugation or genetic fusion and act as an antigen that is recognized by an antibody. The use of epitope tags allows for the detection of proteins where specific antibodies are not available and for targets that are poorly immunogenic.

Epitope tag antibodies allow for powerful qualitative and quantitative analysis via flow cytometry, ELISA, western blot, and microscopy as well as enable affinity purification of the tagged molecule by using tag-specific antibodies coupled to chromatographic resins. Our wide selection of in-house produced and validated epitope tag antibodies is available conjugated to biotin, fluorescein (FITC), horseradish peroxidase (HRP), alkaline phosphatase (AP), and Alexa Fluor® dyes.
