Glyx 13

What is Glyx-13 ? 

Glyx-13, also known as Rapastinel, is a synthetic tetrapeptide derived from monoclonal antibody research. It is widely studied as a functional modulator of the NMDA receptor, which plays a key role in synaptic plasticity and neural communication.

Due to its unique mechanism involving glutamatergic signaling pathways, Glyx-13 has attracted strong interest in neuroscience and psychiatric research. It is commonly used in laboratory and pharmaceutical development environments as a high-purity research peptide material.
