Description
BspQI is a type II restriction endonuclease derived from the recombinant protein encoded by the BspQI gene in Bacillus sphaericus expressed by E.coli.
Recognition sequence is 5'-GCTCTTCN1/N4-3'. Use to digest plasmids to prepare poly(A/T/G/C)-terminated linearized DNA fragments to obtain specific cohesive ends.
This product is produced in accordance with GMP process requirements and supplied in a liquid format.

Shipping and Storage
The product is shipped with dry ice and can be stored at -15℃ ~ -25℃ for one year.
Applications
1. Digest the plasmid to prepare a linearized DNA fragment at the end of Poly (A/T/C/G);
2. Digestion of DNA to obtain specific sticky ends.
Protocol
50 μL reaction system.
This step is suitable for linearization of 1 μg DNA (≥100 nt) and can be scaled up according to experimental needs.
1)Add the following components in sequence:
Components | Volume |
Plasmid DNA | 1-2 μg |
10×Digestion Buffer | 5.0 μL |
BspQI (10 U/μL) | 1.0 μL |
RNase-free ddH2O | Up to 50 μL |
2)Incubate at 50°C 1h.
3)DNA linearization is complete, and subsequent experiments can be performed.
