Immulok

Immulok was a U.S. diagnostics and laboratory products company active in the early 1980s that developed and commercialized immunology, microbiology, and immunofluorescence testing products. Its FDA-cleared product set included viral culture and typing reagents, immunofluorescent antibody assays, tissue immunoperoxidase kits, and radioimmunoassay products, indicating a focus on in vitro diagnostic testing rather than therapeutics. Historical records also show the company held patents on slide-incubation hardware used in immunoassays. The company appears to be inactive today and historical corporate records indicate it was merged out, with later records linking it to Johnson & Johnson-era Raritan, New Jersey addresses. For biotech analysts, Immulok is best understood as a defunct historical diagnostics/medtech company rather than a current drug-development biotech.
