Primary antibodies

Antibodies are large, Y-shaped glycoproteins (also known as immunoglobins) generated by the immune system in response to foreign agents. They recognize antigens specifically and with high affinity and are, therefore, widely used in scientific research to localize, purify, and quantify proteins. They may also be used as therapeutic agents to deliver drugs to specific cell populations.

Primary antibodies are tools used to detect and/or quantify the presence of specific antigens in a range of samples. Our broad portfolio of products includes highly cited monoclonal and polyclonal antibodies, as well as an unrivaled range of recombinant monoclonal antibodies.

Our recombinant monoclonal antibodies deliver many advantages, including batch-to-batch consistency, confirmed specificity, and ease of scalability, so that you can progress your research faster. Click here to learn how our recombinant antibodies can help you to progress faster.

To enhance the flexibility of your experiment, over 10,000 of our antibodies and matched antibody pairs are carrier-free and conjugation-ready, so you can easily find primary antibodies that fit your research’s needs. Click here to discover our carrier-free formats.
