Folate was coupled t,o AH-Sepharose 4B, the gel poured into small columns, and the Sepharose-bound folate reduced in situ to dihydrofolate by dithionite/ascorbate at pH 6 to 7. The dihydrofolate-Sepharose column was used to purify guanosine triphosphate cyclohydrolase I (EC 3.5.4.16) and dihydrofola
