Few basic sites, so low charge states: the singly charged ion near 1,420 and the doubly charged near 710 dominate in positive mode. In negative mode the acidic residues give a clean signal. There are no oxidation satellites to look for, since the sequence has no methionine or cysteine; deamidation at one dalton is the modification to watch on a high-resolution instrument.
It is one of the simplest peptide spectra in the catalogue.
Lysines in the LKKTET motif and elsewhere give it more charge, so it appears as a small envelope of two to four states. Its mass depends on its exact sequence and acetylation state and is stated on the certificate. Deconvolution gives the neutral mass for comparison with the expected value.
If the certificate showed a mass near 4,963 the vial would contain the full protein, not the listed fragment.
Two calculated masses, two observed masses, two differences. A certificate reporting a single mass for a two-component product has described one of them.
The BPC-157 + TB500 blend is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for each component of the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
