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-2024-004548
High endotoxin 5.32 EU/mg on high-purity material vs purity suggests water quality at the fill step. If the lot was lyophilised from non-purified water, this is the expected finding.
AX-2024-005037
High endotoxin 6.88 EU/mg on high-purity material vs purity suggests water quality at the fill step. If the lot was lyophilised from non-purified water, this is the expected finding.
