Glycine (TC Grade) — 5g

Description

🌿 Glycine (TC Grade) — the simplest amino acid and a standard component of MS medium vitamins at 2 mg/L. Serves as a precursor to purines, porphyrins, and serine in plant cells.

💡 Glycine in the MS vitamins mix

Murashige & Skoog medium includes glycine at 2 mg/L as part of the organic supplement. Glycine contributes to: purine biosynthesis (glycine is directly incorporated into the purine ring), glutathione synthesis (antioxidant tripeptide), and one-carbon metabolism via serine hydroxymethyltransferase. While plants can synthesise glycine, exogenous supplementation supports rapidly dividing callus cells where demand exceeds endogenous synthesis.

🔬 Standard inclusion

MS standard: 2 mg/L glycine. Some protocols use 5–10 mg/L for high-density suspension culture. Glycine is heat-stable — can be autoclaved with the medium (unlike glutamine or ascorbic acid).
