[ Product Description ]
Calcium is the most abundant mineral which accounts for 1.5-2.9% of body weight, and is an important element in the formation
of bone and cartilaginous tissues. In the human bodies, 90% of the calcium is present as hydroxyapatite in bone, 1% is in cells,
and 0.1% is in the blood. Calcium is known to plays important roles in various physiological functions such as osmotic
homeostasis, blood clotting, muscle atrophy, nerve stimulation, and the activation of enzymes. In blood, 45% of calcium is
attached to albumin or globulin, 10% is present as phosphate salt, and 45% exist as free ion.
[ Assay principle ]
o-Cresolphthalein Complexone (OCPC) and calcium can form a chelate complex with deep red color.
The concentration of calcium can be determined by the absorbance at 570 nm. Although most OCPC-based calcium assay has
sigmoid-shaped calibration plot, the calibration plot of this kit is linear and the calcium concentration can be estimated
by simple one-point calibration.
