Gelcarin GP-812 is a well-tested source of carrageenan for use in Plant Tissue Culture. It forms a clear, pale brown firm gel. Gelcarin should be dispersed in cold water and then heated above its solubility temperature to obtain maximum functionality. Upon cooling and in the presence of appropriate cations (K+, Ca2+) carrageenan polymers align themselves to form double helices. These helices associate with divalent cations, i.e. -calcium, to form a gel matrix
