I.

Ordering

#Do I need to request a quote before I can order?
No. Every catalog SKU has a public price, the same for every lab. Choose 1, 6, 12, or 24 bottles. Bulk savings are published for everyone. No need to negotiate—you’ll always get our best prices. Add your bottles to the cart and see the shipping total before payment.
#Is there a minimum order quantity or dollar amount?
No minimum order. You can buy a single bottle.
#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.

Shipping & storage

#How fast do you ship?
In-stock items ship the same business day when ordered before 1pm ET, or the next business day after the cutoff. Items not in stock ship in 3 calendar days. Carrier transit starts after dispatch and is shown at checkout. Orders ship together when all items are ready. Eligible addresses less than a 40-minute drive from Cambridge, MA can choose free hand delivery, with coffee on us.
#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?
If a cold-chain product arrives warm, a dry-ice product has thawed, or all the dry ice is gone, contact us before using it. We will arrange 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?
Follow the storage instructions and expiry or retest date on your bottle. An unopened shelf life does not establish how long a product remains suitable after opening. Check the product datasheet for any published opened-bottle limit, or contact us with the SKU and lot number for guidance.

Documentation

#Where do I get a Certificate of Analysis for my lot?
Open your shipped order in your account, or scan the QR code on your bottle to open the lot certificate page. Sign in with the account used for the order if prompted. Before buying, you can download a sample CoA from the product page; samples show the certificate format and do not report results for a supplied lot.
#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. Download public datasheets and SDS from the product page. For a lot-specific CoA, open your shipped order or scan the QR code on the bottle; sign in if prompted. Contact us with your order reference and lot number if the certificate is unavailable.
#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.
