Composition

RBX-3RT.

RBX-3RT is a synthetic peptide of 39 amino acids carrying a fatty-acid side chain attached through a linker. That acylation is why its molecular weight is several times that of a short peptide.

It is supplied as a lyophilized powder in a sealed vial. The full modified sequence and the analytical result for your lot appear on the certificate issued with the order.

Listed under a catalog code. Full identification, including CAS number, molecular formula and molecular weight, is published in the specification and confirmed on the certificate.

We do not give guidance on preparing, using or applying any material. Whether a compound suits your research is for you or your institution to decide.
