Trial Size Antibodies

Trial size antibodies let researchers test an antibody's suitability before committing to a larger purchase. St John's Laboratory offers over 13,000 unconjugated primary antibodies through the Antibody Validation Project, launched in 2014, and refunds the value of the antibody if you return your results. Look for the AVP logo on individual product pages to take part.
