someone explain pentadecapeptide to me like I have not read a paper in years
Question in the title, detail here: someone explain pentadecapeptide to me like I have not read a paper in years. It is a fifteen-residue peptide with a published sequence, which makes synthesis straightforward and makes identity verification the meaningful test rather than an optional extra. Short peptides in…
Cosigning that the papers are more modest than the summaries of them. That is true across this whole site and especially here.
Ask for the theoretical mass alongside the measured one. It is a one-line addition to a certificate and it converts a purity claim into an identity claim.
sequence confirmation is the test worth paying for
Sent a vial to PeptideMeter: 99.6% against a claimed 99.0%, with the mass confirming the sequence. Both halves mattered to me.
a fifteen-residue peptide is easy to make and easy to make badly

zaid_eriksen is right that a pure something-else is still something else.
identity, quantity, stability — three separate questions
short peptides are cheap, which cuts both ways
