As a Tyr Gly Gly Phe Met supplier specializing in Enkephalin receptor binding assay reagents, we solve your challenges with high-purity peptides, rapid USA delivery, and cost savings up to 37% vs. competitors – trusted by top pharma labs.
Get Free Quote in 24hIn the fast-evolving field of neuroscience research, securing a reliable Tyr Gly Gly Phe Met supplier for Enkephalin receptor binding assays is critical. Tyr-Gly-Gly-Phe-Met, commonly known as Met-enkephalin, is a pentapeptide (molecular formula C27H36N6O6S, MW 573.68) that serves as the gold-standard ligand in opioid receptor studies. As a leading Tyr Gly Gly Phe Met supplier Enkephalin receptor binding assay provider, Global Technology Co., Ltd delivers research-grade peptides with >99% HPLC purity, lyophilized for stability, and fully compliant with US FDA import guidelines for research use.
Why does this matter to you, the purchasing manager or technical director in a pharma lab or CRO? Enkephalin receptor binding assays measure the affinity (Ki values) of novel compounds to mu, delta, and kappa opioid receptors. Low-quality Met-enkephalin leads to high background noise, inconsistent IC50 results, and wasted runs – costing your team thousands in reagents and time. Our GMP-certified production ensures batch-to-batch consistency, with COA including MS, NMR, and amino acid analysis. Sourced from our Henan Province facility, we ship to USA ports in 7-10 days via DHL/FedEx, dodging the high shipping costs plaguing Western suppliers.
Drawing from 15+ years in peptide synthesis, we've optimized the solid-phase Fmoc synthesis for Tyr Gly Gly Phe Met, yielding trifluoroacetate salts stable at -20°C for 24+ months. For Enkephalin receptor binding assays, our peptide exhibits Kd = 5.5 nM at delta receptors (rat brain membranes), validated per standard [3H]-Met-enkephalin protocols. This precision supports high-throughput screening (HTS) in 96-well formats, accelerating your drug discovery pipeline by 25-30%.
You face relentless pressure to cut costs while maintaining assay reproducibility. Here's what our 200+ US clients tell us:
