Glycine Receptors

The amino acid glycine is a major inhibitory neurotransmitter in the vertebrate CNS. Glycinergic synapses are particularly abundant in spinal cord and brain stem, but are also found in higher brain regions including the hippocampus. The inhibitory actions of glycine are potently blocked by the alkaloid strychnine, a convulsant poison in man and animals.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
