A highly specific assay for plasma vitamin B.sub.12 levels in humans is disclosed. The assay employs intrinsic factor preparations obtained from mouse or rat stomachs, which intrinsic factors are free of R-protein and thus react specifically with vitamin B.sub.12 in a competitive binding assay...
TO DETERMINE VITAMIN B12, Incubate a test solution with two or more receivers R1 and R2, R1 OF WHICH PROVIDES EASY TO SOLID PHASE bond and R2 carries a label. AS ONE OF BOTH RECEIVERS, RECEIVER IS USED FOR PROVIDING POWER WITH MONOCLONAL ANTIBODY A BINDER specific about B12 WITH AN AFFINI...

New rapid and simpler procedures, using immunoaffinity columns, have been developed for the determination of vitamin B12 in a range of samples including three different US National Institute of Standard and Technology (NIST) Reference Materials, infant formula, powdered energy drinks and bars, wheat ...
To determine vitamin B12, a sample solution is incubated with at least two receptors R1 and R2, of which R1 mediates binding to the solid phase and R2 is labelled, where the receptor used as one of the two receptors R1 or R2 contains a monoclonal antibody which is capable of specific bin...
