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-2026-042623
8.50 EU/mg is at the sensitivity limit of VendorInvestigate's LAL method. The true value is unspecified; treating this as a point estimate is overstating precision.
AX-2025-018423
7.31 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.
