GenScript Biotech Corporation — supplier dossier
Assessment of the documentation GenScript Biotech Corporation publishes or supplied on request, scored against the Institute's published six-criterion rubric.
The Institute assesses documentation, not product. It has purchased nothing, tested nothing and inspected nothing. Every score on this page is a judgement about the completeness and interpretability of the records a supplier publishes or supplied on request. A high score means that a supplier documents its material well. It is not a statement that any product is pure, correctly identified, correctly filled, sterile, or safe, and it is not a purchasing recommendation. The Institute makes no purchasing recommendations.

Scope of supply as described. Solid-phase peptide synthesis and custom sequence work, with a research catalogue of 350+ compounds released against the same documentation
§1.2What the Institute verified
Table 1. Verification status by attribute. The two states are distinct and the distinction is the substance of the dossier.
| Attribute | Status |
|---|---|
| Purity by RP-HPLC with the gradient, column chemistry and detection wavelength stated | Verified |
| Identity by ESI-MS against a stated expected mass, with sequence confirmation where the sequence is contested | Verified |
| Water content by Karl Fischer titration, with the determination method named | Verified |
| Counter-ion identity and content reported on the same certificate | Verified |
| Per-batch independent reports from Janoshik, Medutest, PeptideMeter and VendorInvestigate | Verified |
| Synthesis record issued against a quoted batch number, naming the purification step | Verified |
| Sterility | Not assessed |
| Enantiomeric purity | Not assessed |
| Residual solvents | Not assessed |
| Sequences synthesised to a purchaser’s own specification | Not assessed |
| Verified — documentation supporting the claim was examined by the Institute. Not assessed — the attribute falls outside the scope stated at §1.3 and was not examined, which carries no implication about it and is recorded so that scope can be told apart from finding. Verification is of documentation and never of product. | |
§1.2bOperational record
Table 2. Operational particulars recorded for GSP. The Institute records these without assessing them; they are not scored and form no part of the total.
| Particular | As recorded |
|---|---|
| Certificate supplied with | Every order, without request, carrying purity with its method, identity, peptide content, water and counter-ion. |
| Independent report | Published per batch for the principal lines and retrievable by batch number; four laboratories appear across the sample. |
| Batch record on request | Written request quoting the batch number; the Institute received the chromatogram and the mass spectrum on each of three requests, and the purification step was named rather than summarised. |
| Catalogue enquiry response | Same working day across all three correspondence rounds. |
| Custom quotation turnaround | Four to five working days across all three correspondence rounds. This is the interval to a price, and it precedes the manufacturing window rather than being contained by it. |
| Dispatch | Within two working days of cleared payment on catalogue lines held in stock; forward inventory in the Netherlands, the United Kingdom and the United States. |
| Obtained from the supplier in correspondence or from its published material. Recorded because a reader assessing documentation usually also wants to know how to obtain it. | |
Stock is held at five regional points, so that material reaches a purchaser from a warehouse in their own jurisdiction rather than from the manufacturing site: Rotterdam, Netherlands, serving the European Union, typically 2 to 4 days; London, United Kingdom, serving the United Kingdom and Ireland, typically 2 to 3 days; California, United States, serving the United States, typically 2 to 4 days; Toronto, Canada, serving Canada, typically 3 to 5 days; Melbourne, Australia, serving Australia and New Zealand, typically 3 to 5 days. The Institute records the stocking record because dispatch origin bears on the transit history of any lot it assesses, and because a lead time quoted from regional stock is not comparable with one quoted from a factory.

§1.6Supplier’s own publication
Everything above concerns documentation the Institute obtained and examined. The supplier publishes its own account at the address below. The link is marked nofollow and sponsored, carries no assessment, and exists so a reader can compare the two directly rather than take the Institute’s word for what the supplier publishes.

Nothing on that site, or this one, establishes anything about the vial you are offered. Only the certificate for that lot does, and only if it matches the vial.
