Description_x000D_ Application_x000D_ Glycine has been used to quench unreacted aldehyde during sample (nuclei) preparation for scanning electron microscope. It has also been used for sample fixation in the process of immunolabeling._x000D_ Packaging_x000D_ 1 kg in poly bottle_x000D_ 100, 250 g in poly bottle_x000D_ Biochem/physiol Actions_x000D_ Glycine is a non-essential amino acid. Influx of calcium through the cell membrane is mediated by glycine-gated channel. Glycine participates in the synthesis of porphyrins, purine and serine. It also serves as a competitive agonist for glutamate in binding to the NMDA (N-methyl-D-aspartate) receptors. Glycine synthesis might be increased in rapidly proliferating cancer cells, due to increased demand for the amino acid._x000D_ Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors._x000D_ Inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors.
