Histidine buffer — living evidence map
The Atlas page holds the claims; this is how its evidence evolved.
Summary
Histidine buffers are widely used in freeze-dried monoclonal antibody formulations, often as histidine-HCl. · pmid:41308842
Mechanism
Under fluorescent light, histidine-derived photosensitizers accumulate in the buffer and mediate oxidation of a formulated antibody; the effect was reduced at pH above 7 or without oxygen. · pmid:21786276
Identity
No public registry record is shown for this page: a buffer is a system of components, not one compound.
Where the evidence actually sits
Proportion of the 2 claims about Histidine buffer standing at each tier. Community volume is shown on the Consensus tab beside this and is never averaged into it.
Living evidence history
2 resolved citations, oldest to newest, coloured by tier. Retractions and contradictions land here as they are recorded.
Structure
No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Histidine buffer yet.
Dose evidence, rung by rung
No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.
