Terms and Conditions

1．Terms

Sangon Biotech will deliver to customer 4.0ug plasmid DNA containing gene of interest. Plasmid DNA will be in pUC vector and provided in lyophilized powder form. Along with the final gene product, Sangon Biotech will provide chromatogram sequencing results, gene report, alignment file, complete nucleotide sequence of the plasmid (cloning vector) including the sequence of the gene insert, and restriction digestion analysis results. All these documents will be copied on a CD sent along with the final product. Upon request, customer may also receive these documents electronically.

No gene synthesis is initiated without a PO number or credit card number. Sangon Biotech accepts credit card (Visa or MasterCard), cheque or wire in payment. Payment term is net 30 days.

2．Turnaround

Sangon Biotech will make its best effort to ship genes with a sequence length less than or equal to one thousand base pairs (1000bp), within ten (10) business days of receipt of an order. Sangon Biotech will make its best effort to ship genes with a sequence length between one thousand base pairs (1000bp) to two thousand base pairs (2000bp), within fifteen (15) business days of receipt of an order. For genes with a sequence length greater than two thousand base pairs (2000bp), Sangon Biotech will provide customer with an estimate of the completion date before manufacture of the gene.

3. High GC Content Genes and Highly Repetitive Genes

In case of genes with high GC content (including regional high GC content genes), as well as highly repetitive genes, Sangon Biotech reserves the right to deliver genes within a more reasonable time frame. The new time frame will be consulted with customer prior to start of gene synthesis. Sangon Biotech may also refuse to fill any order by notifying customer orally or by written notice if the order is technically difficult to accomplish.

4. Custom Cloning Vehicle

Sangon Biotech will charge an extra CDN$200 dollars to subclone the genes of interest into customer’s desired cloning vehicle.

Customer must provide detailed sequence information pertaining customer vector. Any incorrect or false information provided by customer may lead to significant delay of the project. In this case, Sangon Biotech is not responsible for the delay or any consequences caused by the delay.

If subcloning fails due to circumstances beyond control, Sangon Biotech will deliver the final gene product in pUC57. $200 subcloning fee will NOT be charged to customer due to incompletion of subcloning process.

5. Genes with Expression Toxicity

In the event that a designed DNA fragment is toxic to the E.coli host in which it is grown, Sangon Biotech reserves the right to provide 20ug of sequence-verified full length PCR fragment in place of plasmid DNA. Customer agrees to pay the full invoice amount.

Genes that Fail To Be Synthesized in Full Length in Standard Vector or as a PCR Fragment

Sangon Biotech makes best effort to synthesize the full length gene in our standard vector pUC57. Should Sangon Biotech be unsuccessful in generating the full-length sequence in the standard vector or as a full length PCR fragment (due to sequence instability, toxicity, GC rich areas, repeats, etc.), client is not obligated to make ANY payment to Sangon Biotech Should client be willing to receive sequence-verified PCR fragments, Sangon Biotech reserves the right to ask a proportion of the original price (up to 50%) to cover labour and material cost.

6. Cancellations

For any genes, customer may cancel the order after reaching an agreement with Sangon Biotech.

• If Sangon Biotech has received the order, but has not initiated the project, customer is entitled to cancellation of the order without any penalty.
• If Sangon Biotech has prompted oligo synthesis, but not cloning and/or thereafter, customer may cancel the order, however, customer is obliged to pay 25% of the original price to cover labour and material cost.
• If Sangon Biotech has prompted oligo synthesis, and has started cloning and/or thereafter, customer may cancel the order, however, after agreement with Sangon Biotech. Customer is obliged to pay penalty cost, depending on the stage or status of the project.
• If Sangon Biotech has obtained the correct sequence within specified time frame, customer may cancel the order, however, with full amount paid to Sangon Biotech.

7. Patents

Sangon Biotech serves as a service provider and offers synthesis services of sequences provided by the customer. It is the sole responsibility of customer to verify whether their respective work is result of any infringements of any patents. Sangon Biotech expressly disclaims any liability in this regard.

8. Inspection Policy

Upon receipt of shipped goods, customer shall inspect the shipment promptly for damages, shortages and correct identity of product. Any product that is not identical to the requested sequence will be replaced or authorized for return and credit, at our option. Any claims must be submitted within 3 months of shipment.

9. Warranty

Sangon Biotech guarantees 100% accuracy and match of genes requested. Any claims must be submitted within 3 months of shipment. At the time of shipment, Sangon Biotech keeps a single copy of the gene for unexpected incidents and/or disputes. After 3 months, this copy of the gene will be destroyed permanently. Sangon Biotech reserves the right to refuse handling disputes after period of 3 months.
