Gibco HT Supplement is a liquid mixture of sodium hypoxanthine (10 mM) and thymidine (1.6 mM). HT-supplemented medium is suitable for post-selection rescue to overcome the effects of residual intracellular aminopterin. Once the de novo biosynthesis pathway for nucleosides has been reestablished, HT supplementation can be discontinued.
