If a primer/probe within an existing typing kit malfunctions and a user created a modification of the primer/probe, that modified primer/probe is considered by dbMHC to be an entirely new probe.
The kit that contains this modified primer/probe is considered by dbMHC as an entirely new kit. Therefore, when entering a sequence modification of primer/probe within a kit, a submitter must create a new kit by using Save kit as located within New Typing Kit.
Save kit as will create a copy of the existing kit. The user can then rename the copy of the existing kit, virtually creating a new kit. The user can then go to the kit element frame, Edit Kit Locus Groups and Elements, to remove the old primer/probe from the new kit and replace it with the modified primer/probe.
