SILAC RPMI 1640 Medium is RPMI 1640 basal cell culture medium without L-arginine, L-glutamine, and L-lysine for use during SILAC protein labeling with stable isotope-labeled lysine and/or arginine. RPMI 1640 Medium is widely used for supporting the growth of many different mammalian cells. Cells successfully cultured in RPMI-1640 include HeLa, Jurkat, MCF-7, PC12, PBMC, astrocytes, and carcinomas. We offer a variety of Gibco™ RPMI 1640 modifications for a range of applications. Find the right modification using the media selector tool.

RPMI 1640 Medium is unique from other media because it contains the reducing agent glutathione and high concentrations of vitamins. RPMI 1640 Medium contains biotin, vitamin B12, and PABA, which are not found in Eagle's Minimal Essential Medium or Dulbecco's Modified Eagle Medium. In addition, the vitamins inositol and choline are present in very high concentrations. RPMI 1640 Medium contains no proteins, lipids, or growth factors. Therefore, RPMI 1640 Medium requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). SILAC protein labeling experiments should be conducted using Gibco™ Dialyzed FBS. RPMI 1640 Medium uses a sodium bicarbonate buffer system (2.0 g/L), and therefore requires a 5-10% CO₂ environment to maintain physiological pH.
