Calcium ocpc liquid stable

Calcium OCPC, also known as o-cresolphthalein complexone, is a chelating agent commonly used in clinical laboratories for the measurement of calcium levels in biological samples. It is a colorimetric reagent that forms a complex with calcium ions, producing a color change that can be quantified spectrophotometrically.

The reaction between calcium ions and OCPC involves the formation of a purple-colored complex. The intensity of the color is directly proportional to the concentration of calcium ions in the sample. By measuring the absorbance of the colored complex at a specific wavelength, the calcium concentration can be determined.

Calcium OCPC is often used in automated clinical chemistry analyzers, where it is included in reagent kits specifically designed for calcium measurement. These kits typically contain the OCPC reagent, along with other necessary components such as buffers, stabilizers, and calibration standards. The instructions provided with the kit guide laboratory personnel on the proper use and handling of the reagent for accurate and reliable calcium measurements.

It’s worth noting that while calcium OCPC is a commonly used reagent, there may be variations in specific formulations and protocols among different manufacturers or assay systems. Therefore, it is important to follow the instructions provided by the specific kit or reagent manufacturer for optimal performance and accurate results.
