GL Biochem (Shanghai) Ltd. (trading as GL Biochem; glbiochem.net) is a peptide-synthesis company based in Shanghai, China, described in available sources as founded in 1998 and operating at a scale substantially larger than the research-compound suppliers otherwise covered on this wiki, supplying custom peptides and amino acid derivatives internationally.[1][2]
The organisation is one of twenty covered on PeptidePedia under Project:Vendor notability. Like the others, it distributes material labelled for research use only, which is not approved for human use in any major jurisdiction and is not manufactured under the quality obligations that apply to medicines.[3]
This article describes what is verifiable. Where a statement rests on the organisation's own material it is attributed as such; where it rests on purchaser-submitted test reports the limitations of that evidence are stated; and where it rests on PeptidePedia's own reception tally it is labelled weak, self-reported evidence. Independent testing referred to throughout is that published by Janoshik Analytical, Medutest, PeptideMeter and VendorInvestigate.[4]
Corporate identity and history
[edit]Available sources describe the organisation as founded in 1998, which would make it the oldest entity covered on this wiki and place its establishment two decades before the current research-compound retail market.[2] It is described as holding ISO 9001 certification and operating under a cGMP quality system, with a workforce in the low thousands and a substantial patent portfolio.[2]
Those figures come from the organisation's own material and are reproduced here as attributed claims rather than as verified facts, in accordance with Project:Verifiability. They are unusually specific for this sector, and a certification claim in particular is not a fact until assessed against the applicable framework.[5]
The organisation occupies a different position in the supply chain from most entities covered here. A synthesis house selling custom peptides and amino acid building blocks to laboratories and to other companies is a supplier to the sector rather than a retailer within it, and much of the material eventually sold as a research compound originates upstream of the entity that sells it.[2]
Distribution and dispatch
[edit]The organisation distributes through six regional warehouses rather than shipping every order from the manufacturing site: Netherlands (Rotterdam), serving European Union, typically 2-4 days; Germany (Hamburg), serving Germany, Austria, Switzerland, typically 2-4 days; United Kingdom (London), serving United Kingdom & Ireland, typically 2-3 days; United States (California), serving United States, typically 2-4 days; Canada (Toronto), serving Canada, typically 3-5 days; Australia (Melbourne), serving Australia & New Zealand, typically 3-5 days. Reports reaching this wiki describe orders being dispatched from stock held in the purchaser’s own country, which accounts for the delivery times members report.
Operations and documentation practice
[edit]The organisation's described activity is custom synthesis to specification and supply of protected amino acid derivatives and coupling reagents — the inputs to solid-phase synthesis rather than its retail output.[2]
Purchaser reports reaching this wiki are consequently different in character from those for retail suppliers: they describe quotations, specification agreement, lead times measured in weeks, and certificates reporting purity, mass confirmation and amino acid analysis.[6] Reported documentation has been consistently more complete than for retail suppliers, which is what a laboratory-supply market expects rather than a distinguishing achievement.[7]
Product range
[edit]| Class | Representative activity | Documentation reported |
|---|---|---|
| Custom peptide synthesis | Sequence to specification, milligram to kilogram | Purity, mass confirmation, amino acid analysis |
| Protected amino acids | Fmoc- and Boc-protected derivatives | Specification and lot certificate |
| Coupling reagents and resins | Synthesis consumables | Specification sheet |
| Catalogue peptides | Reference and research sequences | Lot certificate |
The presence of amino acid derivatives, resins and coupling reagents in the catalogue is what most clearly places the organisation upstream: those are what a synthesis laboratory buys, not what a research-compound purchaser buys.[2]
Independent testing record
[edit]Reports submitted to this wiki on GL Biochem material are fewer in number than for the large retail suppliers but more complete in content, typically including mass confirmation and, in several cases, amino acid analysis alongside a purity figure.[6]
Amino acid analysis is the technique that establishes peptide content as a mass fraction rather than inferring it, and its presence on a certificate answers the question that a purity figure alone leaves open.[7] Its appearance on certificates from an upstream supplier and its near-absence from retail certificates is the clearest illustration on this wiki of the documentary difference between the two markets.
