Primary literature evidence

Experimental evidence search

Search paper-level observations with their value, target, assay, evidence sentence, source location, and stable record links. Evidence without a safely standardized sequence remains visible without being misrepresented as a canonical peptide.

Figure 5: P21 polypeptide has a good inhibitory effect on the PC12 cytotoxicity caused by the aggregation of Aβ1-42 at a low concentration ratio (1:0.25 and 1:0.5). After the concentration ratio of P21 reached 1:1, with the increase of P21 concentration (1:2, 1:4), cell viability continued to increase, reaching the maximum at 1:4, which was close to the normal level.

Names such as P1, PEP1, or peptide 1 are paper-local labels. Search results group them by publication and never assume cross-paper molecular identity without sequence or explicit structural evidence.
