Trial Size Antibodies

Test suitability before committing to a full-size purchase

Trial size antibodies let researchers test an antibody's suitability before committing to a larger purchase. Our unconjugated primary antibodies are offered through the Antibody Validation Project (AVP), launched in 2014, which refunds the value of the antibody when you return your results. Look for the AVP logo on individual product pages to take part.

How it works

Test size, full-size confidence

Trial sizes give you a smaller volume of an unconjugated primary antibody so you can run it in your own assay before ordering a full-size pack. Antibodies enrolled in the Antibody Validation Project (AVP), launched in 2014, are marked with the AVP logo on their product page. Submit your validation results and we refund the value of the antibody, regardless of the outcome.
