How to Ship Samples
Everything you need to know before sending cells, DNA, media, or materials to DuneX Biosciences.
Following these guidelines ensures smooth project initiation and cell line integrity.
1. Shipping Address
Please ship all project-related materials to:
DuneX Biosciences LLC
28501 Industrial Blvd, Suite 100
Hayward, CA 94545, USA
Email tracking numbers to:
📧 support@dunexbio.com
Labeling Requirements
Include on the package:
“Attn: DuneX Biosciences — Sample Submission”
Your organization name
Your project reference number (if available)
UN 1845 label for dry ice shipments
2. Shipping Cell Lines
We accept most mammalian cell lines for CRISPR screens, stable cell line engineering, and antibody discovery workflows.
Required Materials
Please provide:
Two (2) frozen vials of your cell line
0.5–2 mL typical storage volume
Cryopreserved in FBS + 5–10% DMSO or comparable medium
Growth medium & culture conditions
Base medium (DMEM, RPMI, or specific custom media)
Serum %, antibiotics, and additives
CO₂ %, temperature, confluency guidelines
Any required special handling notes
If your cells require non-standard media
If your cells cannot grow in DMEM or RPMI, please provide:
1–2 L of your required growth medium
Any specialized growth factors, cytokines, or supplements
Coated culture vessels, if necessary
Coated 6-well plates
Coated T-25 flasks
(e.g., Matrigel®, laminin, fibronectin, collagen, vitronectin)
This ensures consistent growth conditions and minimizes adaptation artifacts.
Shipping Conditions
Ship frozen vials on dry ice
Use FedEx Priority Overnight
Avoid Friday or holiday delivery dates
Include labels indicating cell line name, passage, and date frozen
3. Shipping DNA / Plasmid Material
If providing your own DNA or plasmids for viral packaging or transfection:
Required Amount
10–400 µg DNA, depending on workflow and required viral titer
(We will specify the exact amount after scoping.)
Format Specifications
Concentration: ≥ 0.5–1.0 µg/µL
Buffer: Nuclease-free water or low-salt TE
Include:
Plasmid map (GenBank file preferred)
Full sequence (FASTA)
Optional Services
If you prefer not to prepare DNA:
Plasmid amplification (maxi-prep / mega-prep)
Custom vector construction
Gibson Assembly / Golden Gate cloning
Sequence verification (Sanger or NGS)
Shipping Conditions
DNA can be shipped on dry ice or room temperature, depending on your preference
Use rigid secondary containers to prevent tube cracking
Clearly label plasmid IDs, concentration, and antibiotic resistance
4. Shipping Media, Supplements, and Reagents
f your project requires unique culture conditions:
Please provide
1–2 L of complete or base medium
Growth factors / cytokines / additives
Coated plates/flasks if required
Temperature Requirements
Media & supplements: 2–8 °C cold packs
Proteins / factors: Dry ice or cold packs, depending on stability
Coated plates: Room temp unless otherwise specified
5. General Packaging Guidelines
5. General Packaging Guidelines
Frozen Materials
Use adequate dry ice for 24–48 hours
Insulated shipping container
Indicate UN 1845 and dry ice weight
Liquid Media
Double-sealed bottles
Absorbent padding
Leak-proof secondary container
Documentation
Include inside the box:
