| Source | fermentative synthesis with subsequent purification. |
| Description | S-Adenosyl-L-methionine (SAM) is a substrate for methyltransferases and a cofactor for some restriction endonucleases. SAM provided in 5 mM H2SO4 and 10% EtOH. |
| Storage conditions | Store at -20°Ñ. The SAM solution should be thawed on ice and added into the reaction mixture immediately before the incubation. For use in a methylation reaction the SAM should be diluted to a final concentration of 80 μM. |
| Notes | Formula: C15H23N6O5S
Molecular weight: 399,5 |
| Quality control | the SAM is tested in a reaction of methylation of phage Lambda DNA with DNA-methyltransferase M.HspAI (SE #003). |
