Trial Size Antibodies

Antibody Validation Project

We aim to deliver the best possible service to our customers. And when it comes to exploring new antibodies, we aim to provide the widest range of options for accessibility, convenience and affordability. We do this through our Antibody Validation Project, where our customers have access to trial size antibodies at a fraction of the cost of larger sizes.


Trial size antibodies are available from 10µl to 20µl sizes, starting from ~1mg/mL, which should allow our customers to carry out a variety of applications testing before committing to a larger size for their intended research application.


Most primary antibodies on our store are already well characterised and performance tested for a number of suitable laboratory applications. However, for customers who may also be interested in novel applications or untested models this project may offer additional flexibility in your research approach. We welcome purchases of trial size antibodies for Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Immunoprecipitation (IP), Flow Cytometry (FC) and ELISA applications, and to limit their risk, not their research.


Look out for the AVP logo on eligible products.
