Cambridge Protein Arrays Ltd. -  Your dedicated partner for protein array based screening projects.
Established in Cambridge (UK) in 2010, our academic roots are in protein arrays and protein affinity reagents.

We have contributed to developing the area of protein arrays and are making our expertise available to you. We are European distributors and service providers for HuProt™ human proteome microarrays, the largest human protein arrays available, with more than 23,000 human proteins, representing more than 16,000 human genes on a single slide.
