What is Application?

Select primary antibodies based on the intended application, such as ELISA, fluorescent ELISA (FLISA), western blotting (WB), immunohistochemistry (IHC), immunofluorescent microscopy (IF or confocal), immunoprecipitation (IP), gel shift assays (GS) or other immunoassays. Stated applications for primary antibodies are applications which the primary antibody is suitable for use.

What is Clonality?

Select either polyclonal or monoclonal primary antibody.


Polyclonal antibodies (pAbs) are derived from different B cells, each recognizing a different epitope on the antigen.  


Monoclonal antibodies (mAbs) are produced by a single B cell hybridoma clone and all antibodies from the same clone are identical with a defined specificity for the antigen.

What is Conjugate?

Certain primary antibodies are conjugated to HRP, fluorescent tags or biotin for use in direct immunoassays. Conjugated primary antibodies do not require secondary antibodies for signal propagation. Select the conjugate based on the immunoassay intended for the primary antibody.

What is Sample Size?


Choose antibodies “Yes” to show only antibodies that come in 25uL trial sizes or choose “No” to see all antibody sizes.
