Product Description
B12 (Methylcobalamin) 10mg — Coenzyme B12 Research Compound
Methylcobalamin is the active coenzyme form of vitamin B12, a cobalt-containing molecule essential to one-carbon metabolism. It is a research compound for studying methylation reactions, homocysteine metabolism, and neurological cell signaling. Each vial contains 10mg at ≥98% purity, verified by HPLC.

Mechanism of Action
Methylcobalamin is a cofactor for methionine synthase, the enzyme that converts homocysteine to methionine while regenerating tetrahydrofolate. This positions it at the heart of the one-carbon (methylation) cycle.
One-Carbon Metabolism
As a methyl-group carrier, methylcobalamin is a key tool for studying cellular methylation reactions and folate-cycle biochemistry.
Homocysteine Regulation
Its role in methionine synthase makes it central to research on homocysteine metabolism and associated signaling pathways.
Research Applications
Methylation-Cycle Research
A reference cofactor for studying one-carbon metabolism and methionine synthase activity.
Homocysteine Metabolism
Used to investigate homocysteine-to-methionine conversion pathways.
Neurological Cell Signaling
Studied for its role in nerve-cell metabolism and myelination models.

Reconstitution and Handling in Research
The following summarizes standard laboratory handling for lyophilized research peptides. This product is intended for research use only and is not for human consumption.
Gently swirl to dissolve—do not shake, as agitation can shear peptide structure. The solvent volume selected determines the working concentration for a given research protocol.
Storage and Handling
Lyophilized (unreconstituted): Store at -20°C for long-term stability (up to 24 months) or at 2–8°C for shorter periods, protected from light and moisture. Avoid repeated freeze-thaw cycles.
Reconstituted: Store at 2–8°C and use within 4–6 weeks. For longer storage, aliquot into single-use volumes and freeze at -20°C. See our full peptide storage guide.
Safety Profile in Research
As with all research compounds, investigators should follow standard laboratory safety protocols, including appropriate personal protective equipment (PPE) when handling reconstituted solutions. B12 10mg is for in-vitro and laboratory research use only and is not intended for human consumption, therapeutic use, or diagnostic purposes.

Frequently Asked Questions
What is methylcobalamin used for in research?
Methylcobalamin is used to study methylation reactions, homocysteine metabolism, and neurological cell signaling in laboratory models. It is intended strictly for research use.
How does methylcobalamin differ from cyanocobalamin?
Methylcobalamin is the active coenzyme (methylated) form of vitamin B12, directly usable as a methyl-group cofactor, whereas cyanocobalamin is a synthetic precursor form.
What is the purity of B12 10mg?
Each batch is verified at ≥98% purity by HPLC.
Why Buy B12 10mg from Iron Peak Peptides?
Every batch of B12 10mg undergoes third-party analytical testing—HPLC, mass spectrometry, and endotoxin screening—to verify purity, identity, and composition, with batch-specific quality-assurance documentation included. Iron Peak Peptides maintains full traceability from raw material to finished vial, ships quickly with proper handling, and backs every order with responsive research support. When you choose IronPeak, you partner with a supplier that prioritizes scientific rigor and product quality above all else.
