“…Ross, 1950;Sobotka, Baker, and Frank, 1960;Bauer and Heinrich, 1961;Yavorkovsky and Mai, 1961;Gjersten and Schrumpf, 1962) but the control values we have found agree well with those of Herbert and Zalusky (1961), Worm-Petersen (1962), and Kidd, et al (1963). The finding of a correlation between B12 concentrations in serum and cerebrospinal fluid confirms the reports of Worm-Petersen (1962) and of Simpson (1964).…”

“…XX w. Przez wiele lat poziom kobalaminy w badanej próbie, możliwy był do wykrycia tylko przy użyciu metod mikrobiologicznych. Do tego celu wykorzystywano drobnoustroje Lactobacillus leichmannii [83,88], Euglena gracilis [55,75], Ochromonas malhamensis [26] oraz Escherichia coli 113-3 [9,19]. Przy uży-ciu tych metod możliwe jest jednak oznaczenie sumy korynoidów, a więc oprócz biologicznie aktywnej formy witaminy B 12 , także jej analogów oraz innych związków zawierających pierścień korynowy.…”

“…It was used by Hutner et al (1949) for the assay of the antianaemic factor and the assay was modified by Ross (1950) for the assay of Cbl in human serum. Subsequently, a range of assay organisms have been used with success and, latterly, isotope-dilution methods have replaced many of the microbiological procedures.…”
