Human Vitamin B12 (VB12) ELISA Kit
This assay is a direct competitive inhibition enzyme immunoassay. Antibody specific for Vitamin B12 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells with biotin-conjugated VB12. A competitive inhibition reaction is launched between VB12 (Standards or samples) and biotin-conjugated VB12 with the pre-coated VB12 antibody. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound reagent, a substrate solution is added to the wells and color develops in opposite to the amount of VB12 bound in the initial step. The color development is stopped and the intensity of the color is measured.
|Specificity||This assay has high sensitivity and excellent specificity for detection of human VB12. No significant cross-reactivity or interference between human VB12 and analogues was observed.|
