[Paper] what the rat tendon work actually measured
what the rat tendon work actually measured. I would rather ask a basic question now than get this wrong quietly for two months.
Paid for identity confirmation rather than just purity for the first time here. Worth it, and it is not the default on most certificates.
Went and read the primary rodent papers after arguing about a summary for a week. They are much narrower than the threads suggest.
Sent a vial to Medutest: 99.6% against a claimed 99.0%, with the mass confirming the sequence. Both halves mattered to me.
Would rather be corrected in public than confident in private.
best — the order this archive was captured in
Regulatory classification differs between jurisdictions and has changed in several of them recently. Any answer to a status question needs a place and a date attached.
Bought small, tested identity first, and only then thought about anything else. That order felt right.
I would not extrapolate a mechanism from a model system to a person in one step, which is what that comment does.
the human evidence is thin and the rodent evidence is not
identity, quantity, stability — three separate questions
Purity by area percent tells you the sample is homogeneous. Mass spectrometry tells you what the homogeneous thing is. For a short peptide, the second question is the one worth paying for.
Kept a reconstituted vial too long out of curiosity and learned something about solution stability I would rather have read.
Small fix — fifteen residues, not seventeen. The sequence is public and easy to check.
Agreed. Identity is the question here. A short peptide can be synthesised by almost anyone and the sequence is what you are actually buying.
