Gibco Primary Rat Cortex Neurons, Sprague Dawley, are isolated and cryopreserved from Sprague Dawley embryonic day-18 rats. A flexible, ready-to-use, and quality alternative to fresh neurons, each vial contains one million cells per mL. These neurons consistently yield post-thaw viability in the range of 50–80%, have high neuronal purity, and are validated for functionality.

• High viability: post-thaw viability of 50% or greater
• High purity: greater than 70% neuronal phenotype
• Functionally validated: tested for spontaneous synchronous calcium flux and synaptic release activity
