Notes

Calcium Colorimetric Assay Kit (O-Cresolphthalein Method) is specific for calcium.

Procedure

This MC-Reagent Calcium Assay Kit is a direct colorimetric assay based on the O-Cresolphtalein (OCPC) method without deproteinization of the sample. The calcium determination is based on the reaction of calcium with O-Cresolphthalein complexone in alkaline solution, which yields a violet colored complex. The intensity of the color formed is proportional to the calcium concentration in the sample. Absorbance of the Ca2+-O-Cresolphtalein complex is measured at 570nm. Wavelength range of sensitivity: 560 ~ 590nm.
 
Features of this Assay: Quick & Easy to use • Species independent • Highly sensitive, stable and suitable for high-throughput testing • No toxic substances • For cell lysates, serum, plasma and wide variety of biological samples
