Gibco® HAT Supplement is a liquid mixture of sodium hypoxanthine (5 mM), aminopterin (20 µM) and thymidine (0.8 mM). HAT-supplemented medium is suitable for post-fusion selection against unfused or self-fused HGPRT–myeloma cells. Hypoxanthine and thymidine supply preformed purines and pyrimidines for DNA synthesis by hybridomas via the salvage pathway that utilizes HGPRT- contributed by the fused spleen cell. Aminopterin, a folic acid antagonist, inhibits the de novo nucleoside biosynthesis pathway.
