Intended Use:For quantitative determination of Rheumatoid Factor IgM in human serum.
Test Principle:Rheumatoid Factor IgM (RF IgM) ELISA kit is based on binding of RF IgM from serum samples to human gamma globulin immobilized on microtiter wells. After a washing step, anti-human IgM-HRP conjugate is added. After another washing step, to remove all the unbound enzyme conjugate, chromogenic substrate is added and color developed. The enzymatic reaction (color) is directly proportional to the amount of RF IgM present in the sample. Adding stopping solution terminates the reaction. Absorbance is then measured on a microtiter well ELISA reader at 450nm and the concentration of RF IgM in samples is calculated on the basis of the absorbance of the negative, positive, and, calibrator controls.
Storage and Stability:Store all components at 4°C. Stable for 6 months For maximum recovery of product, centrifuge the original vial prior to removing the cap.
