BigDye® Direct Cycle Sequencing Kit
 | Fewer Sequencing StepsThe BigDye® Direct Cycle Sequencing Kit, the latest innovation in the BigDye® product family, simplifies industry-standard Sanger sequencing workflow by combining post-PCR clean-up and cycle sequencing into a single step. "Fantastic kit. The workflow is very simple and skips the post-PCR purification step. Single-stream processing protects sample integrity and identity which is very important in our environment. The kit is priced well.” |
Excellent 5' Resolution with BigDye Direct Cycle Sequencing Kit and POP-7™
Enlarge Image Benefits
- Accuracy of Data: By performing all steps from PCR to capillary electrophoresis in a single tube, reduce the possibility of introducing experimental variability
- Quality of Sequencing: Read as close as one base after the gene specific primer sequence with the use of POP-7™ polymer
- Simplified Sequencing Workflow: Reduce the number of manual handling steps and save time. M13 universal sequencing primers (forward and reverse) are incorporated into kit, reducing need to procure multiple reagents
- Time Saving: Obtain sequence reads up to 40% faster and with less hands-on time using BigDye Direct Cycle Sequencing Kit.

6. Can customers combine other PCR mixes to use with the BigDye Direct Cycle Sequencing Kit? Answer
No, all components of BigDye Direct Cycle Sequencing kit are specially formulated and optimized to work together, and cannot be combined with other PCR master mixes.
7. Can customers use standard gene specific PCR primers? Answer
No, customers are not able to use standard gene specific PCR primers with the BigDye Direct Cycle Sequencing Kit. Customers are required to use universal primers, specifically M13 universal primers. Here is the sequence:M13 universal sequences for primer design
- M13 forward primer sequence: 5’ TGTAAAACGACGGCCAGT 3’
- M13 reverse primer sequence: 5’ CAGGAAACAGCTATGACC 3'
8. Can customers use standard gene specific sequencing primers? Answer
No, customers are not able to use standard gene specific sequencing primers with the BigDye Direct Cycle Sequencing Kit. Customers are required to use the M13 universal primers included in the kit.
9. What is the recommended template DNA concentration, pre-PCR? Answer
The recommended DNA concentration is 4 ng
10. Under what temperature and time conditions is the DNA from the sample stable in the BigDye XTerminator® Purification Kit? Answer
Samples can be stored in BigDye Xterminator Purification Kit, please refer to question #4 for storage conditions.
11. Is it preferable to use fresh PCR product or stored product for use with BigDye Direct Cycle Sequencing Kit? If stored, what temperature conditions should be used? Answer
It is always recommended to use fresh PCR product, but if there is a need to store it, please refer to question #4 for storage conditions.
12. Is it better to store samples dry or in Hi-Di™ Formamide? What is the best temp? Answer
It is recommended to store samples dry at -20°C.
13. Can customers dilute the BigDye Direct Cycle Sequencing Kit? Answer
The BigDye Direct Cycle Sequencing Kit formulation has been optimized to work at full strength. Diluting the product will result in poor results.
14. Is an update to current Data Collection Software or Secondary Analysis Software needed? Answer
Customers will need to download a BigDye Direct Cycle Sequencing Kit Installer to update the mobility files.
