Primary Antibodies

Explore all Primary Antibodies

Atlas Antibodies offer highly validated antibodies targeting all human proteins

Choose over 22,000 primary antibodies for your research. Our antibodies are created using a unique antigen design for optimal specificity, affinity-purified using the immunogen and manufactured using a standardized production process to ensure the highest quality. 

Triple A Polyclonals

Triple A Polyclonals

Triple A Polyclonals™ are rabbit polyclonals developed within the Human Protein Atlas project and made available to the scientific community by Atlas Antibodies. The antibodies are validated on all major tissues and organs in the human body. There are 500 staining images to look at for each antibody to facilitate your decision.

PrecisA Monoclonals

PrecisA Monoclonals

PrecisA Monoclonals™ are mouse monoclonals developed against several carefully selected target proteins. We select clones recognizing unique non-overlapping epitopes and/or isotypes. PrecisA Monoclonals are epitope mapped with defined specificity and isotyped to be ideal for multiplexing.

Antibody Validation

We take great care to validate our antibodies in IHC, WB, and ICC-IF. As an additional layer of security, we perform Enhanced Validation. By using five different Enhanced Validation methods we have the power to validate a wide range of different antibodies.

Antibody Validation

PrEST Antigen

Discover PrEST Antigen™, control antigens for use in antibody applications. PrEST Antigens are used as blocking agents and positive assay controls together with the corresponding primary antibody. The PrEST Antigens are 50-150 amino acid long recombinant protein fragments used as immunogens for the generation of Triple A Polyclonals and PrecisA Monoclonals.
