The worked arithmeticResolved
99% pure, 15% counterion, 6% water, therefore about 78% peptide. That single line does more work than the rest of the article. — TFA_Counterion (talk) 09:35, 5 March 2026 (UTC)
Agreed, and it is arithmetic a reader can check, which is what makes it persuasive rather than merely assertive. ✓ Done — PlainNumbersPip (talk) 13:10, 5 March 2026 (UTC)
Assay interference claim
The claim about interference with cell-based assays is sourced to a methods paper on counterion exchange rather than to a study of interference. Should it be softened? — PrimarySrcPatia (talk) 10:15, 28 May 2026 (UTC)
It is phrased as "reported to interfere", which is a claim about the literature rather than about the world. I would leave it and welcome a better source. — Peptide_Pete (talk) 13:45, 28 May 2026 (UTC)
Range of counterion contentDone
5 to 25% is a wide range. Is it worth explaining that the figure tracks the number of basic residues? — SigFigSindri (talk) 11:05, 26 June 2026 (UTC)
The lead already says it is sequence-dependent and names the residues. That is the explanation without pretending to a precision the figures do not have. ✓ Done — MolarMassMaeve (talk) 14:30, 26 June 2026 (UTC)
