General description

GS21 Supplement is a serum-free neural media supplement designed to improve the overall perfomance of the primary neurons. GS21 is specifically optimized for the propagation and long-term viability of primary rat and mouse neurons in culture, without the need for co-culture with astrocyte feeder cells.


Primary rat and mouse neuronal cell culture.

Features and Benefits

  • Significantly improves long-term viability of rat and mouse primary neurons in vitro.
  • Enhances neurite outgrowth of primary neurons in culture.
  • Supports growth and maintenance of primary neurons at low or high cell density plating.

Preparation Note

Product Dilution:

1. GS21 Supplement is supplied as a 50X concentrate. Dilute 2mL in 100mL of your neuronal basal media.
2. For primary cortical neuron cultures, supplement with 0.5 mM dipeptide glutamine before use.
3. Once combined with media, store at 2 °C to 8 °C in the dark for up to 4 weeks.
