Every report

Every figure below is transcribed from the laboratory's own document, and every card shows how to pull up the original with that laboratory. Two kinds of report appear here: a lot verification, which tests the very lot printed on the vial, and a reference report, an outside test of the batch the manufacturer made.

Overview

PUR-3RT.

Thirty-nine residues long, several of them outside the standard twenty, with a fatty-acid side chain joined to the chain by a linker. That lipid side chain carries the molecular weight to roughly 4,700, well above the 1,000 to 2,000 range of the short peptides we carry.

PuraCore lists this material by code only. For an exact identity, use the CAS number, molecular formula and molecular weight in the specification; each lot's certificate sets out the complete modified sequence.

PuraCore offers no advice on how any material is used, prepared or applied. Deciding whether it fits your research rests with you or your institution.
