    What is B12  ?

    B12 is catalog designation for Methylcobalamin, 10 mg per vial. Methylcobalamin is the biologically active coenzyme form of vitamin B12, not a synthetic peptide. Manufactured under laboratory purification process, supplied as red‑pink lyophilized powder with tested purity ≥98%.

    In laboratory studies, B12 is applied for in‑vitro and pre‑clinical experiments including one‑carbon metabolic pathway, methylation reaction mechanism, nerve‑cell biological assay, homocysteine metabolism and related biochemical‑model research. This item is lab‑grade research raw material only for biochemistry and molecular‑cell research projects.
