Antibodies

Primary antibodies are Y-shaped proteins generated by B cells in the immune system in response to foreign pathogens. We offer a wide range of high-quality primary antibodies that detect specific target antigens with high accuracy and sensitivity. They are a critical component of many immunoassays, especially western blotting, enzyme-linked immunosorbent assays (ELISA), flow cytometry, immunohistochemistry (IHC), immunofluorescence (IF), and more.

Secondary antibodies specifically recognize and bind to other primary antibodies. We provide secondary antibodies that bind to multiple sites on the primary antibody and provide signal amplification. This will help to enhance your sensitivity of detection in a wide range of applications including immunofluorescence (IF), western blotting, ELISA, and flow cytometry. These secondary antibodies allow you to visualize and quantify your target antigens even at low concentrations.

Rabbit monoclonal antibodies are a type of recombinant antibodies that come from cloning rabbit antibody genes into expression vectors before transfecting the vectors into host cells. Due to recombinant technology, the monoclonal antibodies are not susceptible to lot-to-lot variation or cell-line drift, which is when hybridomas (the fusion of B cells and myeloma cells) change expression over time. These rabbit monoclonal antibodies also offer better specificity and sensitivity compared to standard antibodies since they go through multiple rounds of screening and selection for the most optimal binding characteristics.

Tag antibodies are highly specific towards target proteins that have been tagged with epitope tags. They provide a way for you to accurately and efficiently purify and localize a wide variety of tagged proteins in experimental assays; common protein tags include FLAG, HA, Myc, GFP, and His. These tag antibodies are commonly used to study protein expression in western blotting, immunoprecipitation, immunofluorescence, and flow cytometry.
