SILAC Media

Essential Media for Isotope-Based Research

SILAC media is prepared specifically for labeling experiments involving the use of stable amino acid isotopes. Athena provides several of the most commonly used media without L-arginine, L-lysine, L-leucine, and L-methionine, the four most commonly used heavy isotope-labeled amino acids.

Powdered Formulations

The SILAC ingredients are milled to a fine particle size, blended to give a homogenous mix, and filled in moisture-proof pouches. Each pouch contains enough medium to prepare 1 liter of medium.

  • Cost-effective
  • 60% less expensive than liquid
  • Lower shipping costs
  • 3-year shelf life

Ready-to-Use Liquid

The SILAC medium is prepared as a ready-to-use liquid that is sterile-filled and filled in 500 ml bottles. Each bottle is supplied with stock solutions of each of the four missing amino acids. This permits reconstitution of complete medium.

  • Convenient ready-to-use
  • Eliminates prep time
  • Just add sterile amino acids and supplements​

​Larger-volume stock solutions of each of the four missing amino acids can be purchased separately.
