Primary Antibody Categories
Monoclonal Antibodies Choose from over 30,000 monoclonal antibodies, including rabbit, rat, and mouse host-species monoclonals. Monoclonal antibodies offer many advantages including high reproducibility, enhanced specificity, and sensitivity.	Polyclonal Antibodies Choose from over 65,000 polyclonal antibodies, including rabbit, goat, and mouse polyclonals. Polyclonal antibodies have the benefit of recognizing multiple epitopes, providing high antibody affinity. Additionally, polyclonals are recommended when detecting a native protein.
Recombinant Antibodies Browse recombinant monoclonal antibodies to more than 1,600 unique targets, designed to decrease lot-to-lot variability and increase reproducibility. Recombinant monoclonal antibodies provide superior sensitivity and consistency.	Knockout (KO) Validated Antibodies Choose from our selection of over 900 KO validated antibodies. Gene KO is the ideal tool for antibody-specificity validation. To remove unreliability Novus Biologicals participates in global initiatives devoted to standardizing antibody validation.
Conjugated Primary Antibodies Browse primary antibodies that are directly conjugated to over 25 unique fluorescent dyes or reporter enzymes, including a variety of Alexa Fluor^® and Janelia Fluor^® dyes, PE, Biotin, and FITC conjugated antibodies.	Sample Size Antibodies Find a primary antibody in a sample size to test it before purchasing a larger quantity. Trial antibodies in smaller sizes first and find the best ones for your research.
