"Vitamin" assay
The NESM for 10/12 has an interesting article on inactive cobalamine analogues that are present in human serum and confuse the diagnosis of pernicious anemia.
Just a further complication on the identification of "true vitamin." See p. 827 for terminology. And a candidate for a diagnostic reagent.
Yours,
Josh.
