Research Antibiotics, Vitamin B12, USP, 5 grams

Vitamin B12, USP, 5 gram. Vitamin B12 has the largest and most complicated structure of the B vitamins. Vitamin B12 is soluble in aqueous solution at 12.5 mg/mL.

• Category: Microbiology
• CAS Number: 68-19-9
• Molecular Formula: C₆₃H₈₈CoN₁₄O₁₄P
• Molecular Weight: 1355.37
• Mechanism of Action: Vitamin B12 is required for DNA synthesis as it serves as a precursor for the amino acid methionine. This is consistent with a finding that bacterial cells with a vitamin B12 deficiency have significantly less cellular DNA content. In addition, vitamin B12 is converted into s-adenosylmethionine, a broad spectrum methyl group donor for >100 different substrates including DNA, RNA, and a number of proteins.
• Storage Conditions: 2-8°C
• Tariff Code: 2936.26.0000

Microbiology Applications

Because of its role in a number of essential cellular processes, vitamin B12 is frequently used as a cell culture media supplement.
