PRODUCT INFORMATION

Details & documentation

Description

B12 10 mg

Buy B12 10 mg for laboratory research. Each vial contains 10 mg of vitamin B12 as cyanocobalamin in lyophilized powder form.

  • 10 mg: per vial

Vitamin B12 is a family of cobalt-containing corrinoid compounds, the cobalamins, which differ in the group bound to the central cobalt atom. This product is supplied as cyanocobalamin, the stable cyano form of the vitamin, identified by CAS 68-19-9.

Choose the size

B12 is offered in a single 10 mg strength. It is a vitamin compound, not a peptide, so its specification differs from the peptide products on this store.

Cobalamin forms differ in molecular weight and light sensitivity, so records and molar calculations should use the values for cyanocobalamin rather than those of methylcobalamin or other forms.

What the research establishes

Cobalamins are studied mainly as enzyme cofactors. Methylcobalamin is the cofactor for methionine synthase, which links folate metabolism to the regeneration of methionine and S-adenosylmethionine. Adenosylcobalamin is the cofactor for mitochondrial methylmalonyl-CoA mutase. Cyanocobalamin is a stable form that cells convert into these cofactor forms.

This describes the general biochemistry of cobalamins established across many studies. It is not a measured property of this product, and it does not describe the performance of any particular form under specific experimental conditions.

Review the COA and product files

The COA & Documentation page contains the available batch reports and product documentation. Check the lot and strength, which cobalamin form the report identifies and by what method, and the purity method used (typically HPLC).

The strength above describes labeled material, not a measured result for every lot. For handling and storage, consult the records applicable to the lot you hold, including any guidance on protection from light.
