I.
Ordering
- #Do I need to request a quote before I can order?
- No. Every SKU on the site carries its list price. That's the price you pay. There's no quote gate anywhere in the catalog; add a pack size to the cart and check out.
- #Is there a minimum order quantity or dollar amount?
- No minimum order. You can buy a single vial, a single pack size of resin, or a single tube of enzyme.
- #What payment methods do you accept?
- Credit and debit cards at checkout, and wire or ACH on larger orders by request. Approved institutional accounts can pay against a purchase order on net-30 terms instead, covered in the next answer.
- #Do you accept purchase orders / offer net terms for universities and companies?
- Yes. Academic, government, and corporate purchasing offices can be set up on a net-30 PO account. Send the PO, or a request for terms, to support@bramantebio.com, or apply from your account. A first-time institutional buyer goes through a short credit check; after that, POs from the same institution go straight to fulfillment.
- #Can I place an order without creating an account?
- Yes, checkout doesn't require an account. If you already know the catalog numbers you want, the quick-order box on the catalog page lets you paste a list of SKUs and quantities directly into a cart.
- #Can I cancel or change an order after I've placed it?
- If it hasn't shipped yet, yes, contact us as soon as possible with your order number. Made-to-order and temperature-controlled items move into production quickly, so the earlier you reach out, the more likely we can still change it.
- #Where are you based, and how do I reach a person?
- Everything we sell is made, packed, and shipped from one facility in Cambridge, MA. The full postal address, which is also the billing and remit-to address for a purchase order or a vendor-setup form, is 160 Alewife Brook Parkway, STE 1316, Cambridge, MA 02138, USA. Email support@bramantebio.com and a person who works in that building answers, not a ticket queue.
II.
Shipping & storage
- #How fast do you ship?
- In-stock items ship the same business day when the order is confirmed by 1pm ET, next business day otherwise, with 1-2 day US transit. Made-to-order and backordered items show a lead time on the product page before you check out. That's a real number, not a placeholder. Custom work is quoted within 24 hours.
- #What does cold-chain packaging actually look like?
- It depends on the product's cold-chain class, printed on every product page: ambient ships in a standard box with no special packaging; cold pack ships with gel refrigerant sized for a standard transit window; dry ice ships in an insulated container and carries a DG Class 9 hazard label. Lyophilized growth factors and cytokines ship on cold packs by default. Dry ice is reserved for products that must remain frozen, such as competent cells, frozen sera or supplements, and enzymes without a validated non-dry-ice format. Shipping & lead times has the full breakdown.
- #Do you ship internationally?
- Not yet at launch. We currently ship within the United States. If you need product outside the US, contact us and we'll let you know as international shipping becomes available.
- #What if my package arrives warm, or the dry ice has fully sublimated?
- A dry-ice shipment where the dry ice has fully sublimated but the contents are still frozen and cold to the touch is normal at the tail end of a transit window. That's expected behavior, not damage. If a cold-chain product arrives warm to the touch, or a dry-ice product has visibly thawed, contact us before using it. We'll sort out a replacement.
- #How should I store product as soon as it arrives?
- Move it to the storage condition printed on the vial label and lot datasheet immediately. Growth factors and cytokines arrive lyophilized on cold packs by default; their unopened storage temperature is lot-specific. Other product classes vary, so don't infer storage from the refrigerant or leave a cold-chain item on the bench.
- #Do you ship on dry ice, and are there restrictions?
- Yes, but only for the exceptional subset of the catalog that must remain frozen, including competent cells and enzymes without a validated alternative format. Dry-ice shipments are classed as UN 1845, DG Class 9, and move on next-day service. Growth factors and cytokines are lyophilized and use cold packs instead.
III.
Products & quality
- #What does "RUO" mean, and does it apply to what I'm ordering?
- Research Use Only, the product isn't validated or labeled for diagnostic, therapeutic, or other clinical use. It applies to everything we sell, without exception. What varies is the checkout step: most biologics and reagents ask you to acknowledge the restriction before you can pay, while items with no biology in them, like a bare chromatography resin, don't carry that prompt. The restriction is the same either way.
- #How is purity determined, and what methods do you use?
- It depends on the product class. Recombinant proteins are typically assessed by SDS-PAGE and RP-HPLC, each reported as a percentage on the CoA along with the method. The specific method used for a given lot is always named, not just the number.
- #Carrier-free or BSA-carrier?
- Each product page states the formulation. Growth factors are lyophilized from the buffer shown on the page: carrier-free contains no added carrier protein, while the BSA-carrier option includes 0.1% BSA. Reconstitute with the diluent and volume printed on the vial label and lot datasheet, then pick the carrier format that suits your assay.
- #Do you test every lot for endotoxin?
- Yes, for products where endotoxin is part of the release spec, recombinant proteins and cell culture media both carry a stated endotoxin value on their CoA, tested by LAL.
- #What's your policy if a product doesn't perform as specified?
- If a lot doesn't meet the activity, purity, or other spec stated on its CoA, contact us with your order number and lot number. We'll replace it or refund it. We'd rather know about a bad lot than have you quietly work around it.
- #Are your reagents GMP grade?
- No. Every product in the catalog is research use only (RUO), manufactured under a documented QC system in our own facility, not a certified GMP one, and released against the published spec on its page. If you need GMP-grade material, we will tell you that up front rather than sell you an RUO lot for a regulated use.
- #How long is shelf life once a product is reconstituted or opened?
- The validated limit is stated on the vial label and lot datasheet, separately from the unopened expiry. It varies by protein, formulation, and lot, so there is no catalog-wide duration to assume. After reconstituting a growth factor, aliquot as directed and avoid repeated freeze-thaw cycles.
IV.
Documentation
- #Where do I get a Certificate of Analysis for my lot?
- Every shipment includes the CoA for the exact lot in the box. If you need a copy, for a lot already in your freezer, or to review before buying, look it up under Certificate of Analysis with the catalog number and lot number.
- #Where do I get a Safety Data Sheet (SDS)?
- SDS documents are product-level (not lot-specific) and linked directly from each product page, or indexed in the SDS library. Most reagents in the catalog are non-hazardous; the exceptional shipments that still require dry ice carry a DG Class 9 declaration separate from the product SDS.
- #Can I see a full datasheet before I buy?
- Yes, the datasheet is published directly on the product page (spec, bioactivity, storage, handling), and the same file is available as a download under Documents on that page.
- #Can I get a document reissued if I lose it?
- Yes. Datasheets and SDS are always available from the product page. For a CoA, pull it again with the catalog number and lot number. It's a lookup, not a one-time send.
- #Do you provide custom certificates, country of origin, TSE/BSE statements, and similar?
- For products where this is relevant (e.g. animal-derived components like FBS), contact us with the specific certificate your institution or import process requires and we'll confirm what we can provide for that lot.
