Description

INTENDED USE
The Calbiotech Cotinine Direct ELISA Kit is intended for the measurement of Cotinine in Mouse/Rat serum orurine.

SUMMARY AND EXPLANATION
Exposure to tobacco smoke can be detected by measuring nicotine and its metabolites. Nicotine has a short half life and is not used as a marker for tobacco smoke exposure. Cotinine due to its longer half life has been used in research as a reliable marker for smoking status and smoking cessation studies. The Calbiotech Cotinine Direct ELISA Kit is designed for the detection Cotinine in rat serum and urine. It can also be adapted for other fluids.

PRINCIPLES OF THE TEST
The Calbiotech Cotinine kit is a solid phase competitive ELISA. The samples and Cotinine enzyme conjugate are added to the wells coated with anti-Cotinine antibody. Cotinine in the samples competes with a Cotinine enzyme (HRP) conjugate for binding sites. Unbound Cotinine and Cotinine enzyme conjugate is washed off by washing step. Upon the addition of the substrate, the intensity of color is inversely proportional to the concentration of Cotinine in the samples. A standard curve is prepared relating color intensity to the concentration of the Cotinine.
