Creators

Description

An improved simultaneous radioassay for folate and vitamin B12 in biological specimens is described. A sample containing folate and vitamin B12 is contacted with 125I-folate and 57Co-vitamin B12 and their respective specific binders. After separation of the bound and free portions, the radioactivity in the portions is counted and the amounts of folate and vitamin B12 then determined from standard curves. (U.K.)
