[Stability of the main components of an EIA test system for the serodiagnosis of HIV infection]. / O stabil'nosti osnovnykh komponentov test-sistemy IFA dlia serodiagnostiki VICh-infektsii.

The stability of two most important components of the EIA test system for diagnosis of HIV infection, an immunosorbent (HIV antigen adsorbed on polystyrene plates) and antispecies peroxidase conjugate, was studied. The possibility to prolong the shelf life of the test system for at least up to 6 months was demonstrated. At the same time, it is proposed to supplement the existing methods of production control with the conjugate thermostability test developed by the authors who believe that this will allow to exclude conjugates with insufficient stability from the test system kit.
