Membrane Proteome Array: The Leading Solution for Antibody Specificity Profiling

The Membrane Proteome Array is the leading solution for antibody specificity profiling. Our cell-based array contains the largest set of human membrane proteins (including heterocomplexes) assembled to determine specificity and preclinical safety of antibodies, CAR-T cell therapies, and other biotherapeutics.

“MPA technology quickly provided us with the reassurance that Abound Bio’s potent neutralizing antibodies to SARS-CoV-2 did not bind off-target human membrane proteins, which could be associated with toxicity.”

-John W. Mellors, MD, CEO, Abound Bio

“We have been very pleased with the data that we obtained from the Membrane Proteome Array platform. This showed that our antibodies recognize only their select target, and not other membrane proteins in their panel.”
