This product is a type IIS restriction endonuclease derived from the recombinant protein encoded by the BsaI gene in Bacillus sphaericus expressed by E.coli. Its recognition sequence is 5'-GGTCTCN1/N5-3'. 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 provided in a liquid form. Features 1. Complete FDA DMF certification (MF038306) 2. GMP-grade, no animal-derived ingredients, strict quality control and production in strict accordance with GMP standards to ensure the introduction of no animal-derived ingredients. 3. High enzyme cutting efficiency, low star activity, and good lethality. It has high enzyme cutting efficiency and no star activity after 16 hours of reaction at 37°C. It has good lethality after enzyme digestion-ligation-re-digestion test. 4. Superior performance application performance is comparable to competing products Applications Plasmid linearization for mRNA vaccine production, Lentivirus/adenovirus packaging vector construction, Enzyme digestion verification of plasmid preparation, Golden Gate assembly DNA labeling Specifications Expression Host Recombinant E. coli with Bas I gene Reaction Temperature 37℃ Storage Buffer 10mM Tris-HCl, 0.2M NaCl, 0.1mM EDTA, 1mM DTT, 50% Glycerol, 0.2mg/ml OsrHSA pH 7.4±0.2 (25℃) Unit Definition 1 unit: The amount of enzyme required to digest 1 μg of substrate DNA within 1 h at 37℃ in a 50 μL system. Application 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; 3.Linearize plasmid template before in-vitro transcription. Components Components No. Name 10661ES03 (1 KU) 10661ES10 (10 KU) 10661ES60 (100 KU) 10661 Bsa I GMP-grade (20 U/μL) 50 μL 500 μL 5 mL Shipping and Storage This product should be stored at -25 ~ -15℃ for two years. Figures Figure1. No non-specific nuclease residues test 20 U BsaI was incubated with substrate DNA at 37°C for 1 h and 16 h, and DNA band changes were compared by agarose gel electrophoresis. The results showed that there was no non-specific nuclease residue in BsaI. Figure2. The end integrity is good and the effect is consistent with imported brands When BsaI and substrate DNA were incubated in the enzyme digestion reaction system for 16 hours at 37°C, no non-specific degradation of the substrate caused by star activity was detected, indicating that there was no star activity after 16 hours of incubation with BsaI.
