Principle

Vitamin B12 iClia is chemiluminescent immunoassay based on the “competitive” principle.

The Denaturation reagent, stabilizing reagent and samples are mixed, after incubation, neutralization reagent and Vit B12 antibody coated magnetic microparticles are added to reaction and incubate. After incubation, Vitamin B12 of a sample and Vitamin B12 of biotin completes for binding to anti-vitamin B12 antibodies coated magnetic microparticle. After incubation and washing, streptavidin Acridinium ester conjugate is added to reaction mixture. After that Trigger and Pre-Trigger Solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative Light units (RLUs). There is an indirect relationship between the amount of Vitamin B12 present in the sample and the RLUs detected by the optical system. Results are calculated automatically based on the established calibration curve.
