HAT Supplement (50×) 

HAT Supplement can be used to specific selection of HGPRT-myeloma hybridoma cells. The aminopterin inhibits the de novo nucleoside biosynthesis pathway. Hypoxanthine and thymidine supply purines and pyrimidines for DNA synthesis by hybridoma cells via the salvage pathway that utilizes HGPRT contributed by the fused spleen cell. Unfused HGPRT-deficient myeloma cells cannot replicate DNA to proliferate, and unfused spleen cells are mortal, allowing for specific selection of HGPRT-myeloma hybridoma cells.

MCE HAT Supplement (50×) is a liquid mixture of sodium aminopterin (20 μM), hypoxanthine (5 mM), and thymidine (0.8 mM). HAT Supplement can be added to cell culture medium as a selection agent for post-fusion selection of HGPRT-myeloma hybridoma cells used for antibody production.
