Conantokin G

Conantokin G, a 17-amino-acid peptide, is a potent, selective and competitive antagonist of N-methyl-D-aspartate (NMDA) receptors. Conantokin G inhibits NMDA-evoked currents in murine cortical neurons with an IC₅₀ of 480 nM. Conantokin G has neuroprotective properties.

Protocole

All Cell Biology

Primary Embryonic Cortical Neuron Culture
Primary embryonic cortical neuron culture isolates cortical tissue from prenatal rodents, dissociates it into single cells, and maintains neurons in vitro so that neurite extension, neuronal marker expression, synapse formation, survival, and treatment responses can be examined outside the intact brain.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
