Grant appendices on materials have a habit of failing in one of two directions. Either they are so vague that a reviewer cannot tell what will actually be bought, or they are a wholesale transcription of a supplier catalogue, complete with pack sizes and marketing lines, presented as though it were an approved list. The second failure is the more damaging, because it makes an in-vitro project look as if it were assembled by browsing rather than by design. What follows is a practical method for filtering a research catalogue down to the handful of items a grant genuinely needs, and for writing those items up as a documented appendix rather than a formulary.
Why a Catalogue Listing Is Not a Formulary Entry
A formulary is an instrument of sanctioned use: a list of agents approved for administration within a defined population or clinical setting, accompanied by agreed indications and restrictions. That concept has no application to research-use-only materials. Research Sciences states plainly that its products are supplied strictly for controlled laboratory and analytical research, that they are not medicines, medical devices, injectables, treatments or food supplements under UK law, and that they are not for human or veterinary use. An appendix that borrows the grammar of a formulary — agent, strength, a bare purity figure — invites a reviewer to ask a question the document cannot answer: approved for what, and on whose authority?
The corrective is to stop treating each row as an entry and start treating it as a justification. Every material in an in-vitro appendix should be tied to a defined assay, a stated role within that assay, a batch-level document that can be retrieved on request, and a handling route that the named laboratory can actually deliver. Where a material is a candidate treatment arm in a cell-based model, say so and describe the exposure parameters in assay terms. Where it is a positive control or an analytical standard, say that instead. The scientific rationale, not the catalogue description, should carry the row.
There is also a housekeeping argument for keeping the two genres apart. A catalogue is organised for browsing: categories, pack sizes, related items. An appendix is organised for scrutiny: numbered experiments, quantities derived from replicate counts, documentation references, storage commitments. Filtering is therefore an editorial act. It helps to keep a short exclusion log — materials considered and set aside because the assay fit was weak, the storage requirement could not be met in the named facility, or the documentation trail was incomplete. Reviewers rarely penalise a well-reasoned exclusion, and materials managers find the log useful when a purchase request arrives months later without context.
The Three Filters That Do the Real Work
Start with the assay, not the shelf
Before opening any catalogue, write the readout. Which cell line or analytical system, which endpoint, which concentrations, how many independent repeats. Only then should a shortlist be drawn. This ordering prevents the common drift in which a familiar catalogue name becomes the experiment. When shortlisting, read the individual listing rather than the category page: the MT-1 10mg entry, for instance, describes a lyophilised research peptide with published research-context uses such as melanocortin receptor and signalling studies, storage at −20°C protected from moisture and light, and 2–8°C after reconstitution. That level of detail is what you test against your own protocol. It is also a reminder not to carry one product’s technical particulars across to another.
Documentation is batch-level, not brand-level
The shop describes a CoA for every product, HPLC-based purity and identity testing, independent analytical verification, and final UK quality checks before release. Those are the claims to cite, and they should be cited as published wording that needs reconfirming on the live site at the point of order. What belongs in the appendix is narrower: the specific certificate that accompanies the specific batch. Note that restocked items may share an Internal Test Reference with earlier stock; an ITR links to associated sample testing reports but does not confirm that separate deliveries come from the same production lot or have been independently tested on each occasion. Vial cap colours vary and are not an indicator of identity, quality or manufacturing origin. Vial labels combine the SKU code and expiry date, for example BPC10-03/27, and that reference is the one to quote both in the appendix and in any query about documentation. Where the homepage’s listed CoAs are concerned, attribute the wording and tell readers to open the certificate attached to their own batch.
Handling feasibility as a pass/fail criterion
Lyophilised material is expected to be stored at −20°C or below, sealed with desiccant and protected from moisture, heat and light, with repeated freeze–thaw cycles avoided; reconstituted material is less stable and is held at 2–8°C for short-term laboratory use. If the laboratory named in the application cannot meet that regime, the material should be filtered out at draft stage rather than discovered as a problem at delivery. Two further catalogue facts belong in the filter: all peptides contain trace amounts of mannitol as an excipient, which is worth declaring where assay interference is being considered, and the shop does not supply blended peptides, recommending instead that items be bought individually and combined only within a controlled experimental design. A proposed combination should therefore appear as separate lines, not as a single shorthand entry. When you Buy peptides uk from the all-products category, record the exact published catalogue name, strength and pack alongside your internal shortlist ID so the paper trail survives staff changes.
Writing the Appendix: Quantities, Solvents and Procurement Notes
A workable appendix is a table with fixed columns, applied consistently. Suggested fields: experiment or assay identifier; material as published in the catalogue, including strength; role in the assay; quantity and the calculation that produced it; documentation reference; storage and handling commitment; solvent and reconstitution plan; research-use-only statement; procurement note. The quantity column is where most credibility is won or lost. Derive it from wells, replicates, working concentration and a stated margin for repeats, not from the nearest pack size. Anything that reads like stockpiling should be cut.
Solvents and accessories deserve their own lines rather than being folded into a peptide row. The site lists 10ml Mixing Water and Bacteriostatic Water 10ml under both wordings, and a storage container as a separate catalogue item, so the appendix should reflect that separation. Reconstitution planning stays inside the in-vitro workflow: diluent volume and target concentration for the assay, prepared in a clean environment, with vials allowed to reach ambient temperature before opening and only the amount required for the experiment removed. The free reconstitution calculator described on product pages and in the FAQs is a laboratory tool only and must never be used for human or veterinary dosing, a restriction that is worth stating in the appendix footnote so no reader misconstrues the intent.
Procurement language should be factual rather than promotional. The site states that orders are dispatched the next working day, shipped by Royal Mail Tracked 24 with delivery described as an estimate rather than a guarantee, that returns are not accepted once dispatched, and that refunds apply only for damage, incorrect supply or quality issues. Payment is described as bank transfer or Open Banking rather than card. None of these should be presented in a grant as a commitment; the appendix can note that lead times and fulfilment terms are to be reconfirmed at checkout. Finally, before submission, re-open each certificate listed, check the batch reference matches the vial label format, and confirm that every row still carries the statement that materials are research-use-only and not for human or veterinary use.
