Section 2

Annotations

Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it.

AX-2026-041428
5.51 EU/mg is elevated relative to the index median and the record shows no depyrogenation step. If this material will be reconstituted in aqueous buffer for any downstream use, that endotoxin load is a risk.
AX-2026-042838
Purity 97.96 % and endotoxin 6.70 EU/mg are unrelated — purity measures synthesis quality, endotoxin measures fill-step water quality. The combination here is coherent and expected together.
