Lab-grade vitamin B12 (cyanocobalamin) used as a reference compound in cell and metabolism research.

B12 (cyanocobalamin) is the most stable lab form of vitamin B12. It's a cobalt-containing molecule used as a reference standard in biochemistry and cell-culture experiments — not a peptide, but a research-grade compound that researchers regularly need on the bench.
How it's been studied: B12 is a cofactor — basically a helper molecule — for two key enzymes that handle methionine and odd-chain fatty acid metabolism. Lab studies use it to investigate one-carbon metabolism, how cells handle homocysteine, and methylation chemistry that controls gene expression.
Where you'll see it in research:
Handling notes: Light-sensitive — keep it in the original opaque vial. Cyanocobalamin is the most shelf-stable form for research use.
