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-2026-041708
5.66 EU/mg but the material was passed through a sterile sterile filter. Some filters leach endotoxins; the measurement does not distinguish material from filter contribution.
AX-2025-020641
Endotoxin determined but the LAL method is not stated. Kinetic chromogenic and gel-clot give different results and different sensitivity. The value cannot be interpreted without knowing which.
