Upon submission, dbMHC creates a unique global ID number for each primer/probe/mix/kit submitted. This global ID consists of three letters for the submitting institution and seven digits.
dbMHC uses the global ID number to store the entire history of a reagent. The global ID number will never change, but every time a user edits the sequence of a submitted primer/probe/mix/kit, that edit is given an incremental version number. Thus, all previous versions of a particular primer/probe/mix/kit are consequently accessible, and submitted primers/probes/mixes/kits can never be deleted.
A “local name” is the identifier given by submitters to their primers and probes.
