Welcome to PeptidePedia Wiki

Chinese Peptide Company — Chinese Peptide Company Co., Ltd. (trading as CPC; chinesepeptidecompany.net) is a peptide manufacturer trading as CPC from Hangzhou, Zhejiang, China, incorporated in 2001, with a catalogue spanning research peptides and custom synthesis and a documented history in the peptide-chemistry sector.[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]…

• … that GL Biochem (Shanghai) — 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]
• … that WuXi TIDES — a research-compound supplier trading as WXT from Wuxi, Jiangsu, China, incorporated in 2002 and distributing peptides, oligonucleotides and related research materials with batch documentation and tracked international shipping.[1][2]
• … that Glucagon-like peptide-1 — a 30- or 31-residue peptide hormone released from enteroendocrine L cells of the distal small intestine and colon in response to nutrient ingestion.
• … that Guangzhou JEEP Biotechnology — a research-peptide manufacturer based in Guangzhou, Guangdong, China, trading as JEEP Peptides, with a catalogue concentrated on incretin analogues and a substantial associated third-party testing record.[1][2]

• … that ChinaPeptides — a peptide supplier trading as QYB from Shanghai, China, incorporated in 2008, whose catalogue centres on custom synthesis alongside a range of stock research peptides.[1][2]
• … that Lyophilisation — a dehydration process in which a solution is frozen and the ice is then removed by sublimation at a pressure below the triple point of water, leaving a porous solid whose volume approximates that of the original fill.

Cold chain — A cold chain is the unbroken temperature-controlled storage and transport that keeps a product within its labelled conditions from manufacture to use.
