Product Details
Cobalamin functions as an obligate cofactor for only two enzymes in human biology, which makes Vitamin B12 a precise research tool for studying a narrow, well-defined set of biochemical reactions.
- Methionine synthase cofactorCobalamin cycles between methylcobalamin and cob(I)alamin states while shuttling a methyl group from 5-methyltetrahydrofolate to homocysteine, generating methionine and tetrahydrofolate.
- Methylmalonyl-CoA mutase cofactorIn its adenosylcobalamin form, the same core structure supports a separate mitochondrial reaction distinct from the cytoplasmic methionine cycle.
- Supplied at 1000 mcg/mLThe standard research concentration for this product.
Purity Verification and COA Access
Every batch of Vitamin B12 ships with a lot-specific certificate of analysis, allowing a researcher to confirm identity and concentration against the exact vial received rather than a generic specification sheet.
Why Cellugenix for Vitamin B12?
Here's what stands behind each vial before it reaches your bench.
99% HPLC purity
An outside facility confirms purity and identity independent of our own process.
On-file documentation
The COA for this lot can be pulled up whenever it's needed.
Quick turnaround
Orders are dispatched promptly with tracking attached.
Stability-focused packing
Shipping materials are chosen to keep the solution intact in transit.
Storage and Handling
Vitamin B12 solutions are photosensitive, so light exposure matters as much as temperature when it comes to maintaining stability.
- Keep away from lightStore the vial in its original packaging or an amber container to limit photodegradation.
- Maintain cold storageRefrigerate according to the temperature range specified on the label.
- Consult the full guideDetailed instructions before lab handling and avoiding repeated freeze-thaw cycles.

Frequently Asked Questions
Is Vitamin B12 restricted to laboratory buyers?
Yes, this product is sold exclusively to qualified researchers conducting laboratory-based scientific work.
What makes cobalamin useful as a research tool specifically?
It serves as the required cofactor for just two known human enzymes, methionine synthase and methylmalonyl-CoA mutase, which narrows its research relevance to specific, well-characterized biochemical pathways.
How can I confirm the concentration and purity of a specific batch?
Each lot of Vitamin B12 has its own certificate of analysis, searchable through our COA library by batch number.
Does Vitamin B12 carry approval for use in humans or animals through this product?
No, it is not approved or intended for human or animal administration, diagnosis, or treatment.
Why does storage guidance emphasize light exposure for this compound?
Cobalamin is known to degrade under light exposure, so handling instructions address that alongside standard temperature control.
