VitroView Alizarin Red Stain Kit (#VB-3008)
 
Description
Alizarin Red Stain kit is used for identifying calcium on tissue sections. Calcium forms an alizarin red S-calcium complex in a chelation process. The reaction is not strictly specific for calcium, since magnesium, manganese, barium, strontium, and iron may interfere, but these elements usually do not occur in sufficient concentration to interfere with the staining.
