WuXi TIDES (revision 18)

WuXi TIDES (WuXi AppTec Testing Division) (trading as WXT; wuxitides.net) is 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]

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]

The organisation dates its operations to 2002, which makes it among the older entities covered on this wiki and predates the current research-peptide market by roughly a decade.^[1] Its own material presents that longevity as continuity with a contract-research heritage in oligonucleotide and peptide chemistry, and the breadth of its oligonucleotide listings is consistent with a technical base wider than peptides alone.^[2]

The trading name presents a difficulty this article has to address directly rather than resolve. "WuXi" is a place name — the city of Wuxi — and is also an element in the name of unrelated and much larger contract-research organisations headquartered in the same region. No source available to this wiki establishes a corporate relationship between them, and none should be inferred from the shared toponym. Editors have repeatedly discussed the point; see the talk page.

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.
