Powder

Supplier: MP Biomedicals

A vitamin/enzyme cofactor found in milk, eggs, malted barley, liver, kidney, heart, leafy vegetables. Richest natural source is yeast. Occurs in the free form only in the retina of the eye, in whey, and in urine; bioactive forms occurring in tissues and cells are riboflavin monophosphate and flavine-adenine dinucleotide. Used as a photoinitiator for polymerization of polyacrylamide gels. It forms free radicals in aqueous solution in the presence of light. Riboflavin photodecomposes to leucoflavin. No free radicals are formed in the absence of oxygen but traces of oxygen allows for leucoflavin to reoxidize with free-radical generation. The catalysts TEMED or DMAPN are commonly added to speed up the free radical formation. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for electrophoresis. Riboflavin is commonly used in the stacking gel for non-denaturing polyacrylamide electrophoresis because native proteins can be senstive to persulfate ions from ammonium persulfate. Another advantage of riboflavin over ammonium persulfate is that it will not start polymerization until the gel is illuminated. Riboflavin causes less denaturing than other initiators. Gel strength can be improved when used with PTO (Pyrithione). Soluble in 0.1 M Sodium Hydroxide (50 mg/ml - clear, yellowish-orange solution); only slightly soluble in water.

Vitamin D3 is the naturally occuring form of vitamin D3. Vitamin D3 mediates intestinal calcium absorption, bone metabolism, and probably muscle activity. It acts as a hormone precursor since it requires two stages of metabolism: first to 25-hydroxycholecalciferol; then to 1 , 25-dihydroxycholecalciferol.
