Product introduction
Summary

1.? Overview:

Vitamin B12 is a nutrient that helps keep human body’s blood and nerve cells healthy and helps make DNA, the genetic material in all of cells.

2.? Principle:

The basis of the measurement is the antigen-antibody reaction. Antibodies are connected to the column and the VB12 in the sample is extracted, filtered, and diluted, and then passed slowly through the VB12 immunoaffinity column. The target substances bind to the antibodies in the column and the immunoaffinity column is then washed to remove other unrelated substances that have not been bound. VB12 is eluted with methanol and then injected into an analytical instrument for detection.
