How We Can Help

Product Selection & Experimental Planning

Not sure which product best fits your application? We can help you choose and optimize:

• rAAV serotypes and promoters for tissue/cell targeting
• Lentiviral systems for stable expression or knockdown
• shRNA/siRNA design strategy and control selection
• Plasmid constructs, reporters, and regulatory elements
• Dosing ranges, injection routes, and study timelines

Troubleshooting & Optimization

If something isn’t working as expected, we’ll work with you to identify root causes and next steps:

• Low transduction/transfection efficiency
• Unexpected expression patterns or weak signal
• Cell viability issues or toxicity
• Vector yield/titer concerns
• Purity, aggregation, or storage/handling questions
• In vivo delivery considerations (route, volume, timing)

Documentation & Compliance Support

We can provide or help interpret:

• Certificates of Analysis (CoA)
• Product datasheets and protocols
• Storage and stability guidance
• Biosafety and RUO (Research Use Only) considerations
• Shipping and handling recommendations

Before You Contact Us (Recommended)

To help us respond faster, please include as many of the following details as possible:

Order & Product Information

• Catalog/SKU # and product name
• Lot # (if available)
• Vector type (AAV/LV/plasmid/reagent), serotype, promoter, transgene
• Titer (VG/mL, TU/mL, or PFU/mL as applicable) and volume received

Experimental Details

• Cell line or animal model (species/strain/age/sex if relevant)
• Multiplicity of infection (MOI) or dose used
• Delivery route (in vitro / in vivo), injection volume, schedule
• Timepoints for readout and assay type (IF, WB, qPCR, luciferase, flow, etc.)
• Controls used (positive/negative/vehicle/mock)

Handling & Storage

• Storage temperature and duration
• Freeze-thaw cycles
• Diluent/buffer used and any filtration steps

If you’re not sure what to provide, don’t worry—send what you have and we’ll guide you.

Frequently Asked Questions

Do you provide help with in vivo study design?

Yes. We can advise on common dosing ranges, timelines for expression, and practical considerations for delivery routes—especially for rAAV studies. Final experimental design decisions remain with the investigator and must follow institutional approvals and biosafety requirements.

Can you review my plasmid map or sequence before ordering?

Yes. Send your map/sequence and a short description of your goal. We’ll flag potential issues (e.g., packaging constraints, promoter compatibility, cloning strategy) and suggest improvements.

Can you troubleshoot a low titer or low expression result?

Yes. We’ll help you evaluate likely causes such as construct design, cell type permissiveness, promoter choice, dosing, handling, assay sensitivity, and timing.
