Selection of Selection of hybridomas in hybridomas in HATHAT ((HHypoxanthine, ypoxanthine, AAminopterine and minopterine and TThymidine)hymidine) medium medium
Metabolic pathways relevant to hybrid selection in medium containing hypoxanthine, aminopterin and thymidine (HAT medium).
When the main synthetic pathways are blocked with the folic acid analogue aminopterin (*), the cell must depend on the “salvage” enzymes HGPRT and TK (thymidine kinase). HGPRT (-) cells cannot grow in HAT medium unless they are fused with HGPRT (+) cells.
