产品介绍

限制性内切酶简称限制酶,是一类可识别特定的脱氧核 苷酸序列,并对每条链中特定部位的两个脱氧核糖核苷 酸之间的磷酸二酯键进行切割的核酸内切酶。BsaI 是一 种 IIS 型限制酶,能识别非回文序列,并在识别序列外 部切割产生粘性末端。

注意事项  

(1)Dcm、CpG 和 EcoB I 的甲基化修饰会损害本品的切割活性。 

(2)未纯化的 PCR 产物具备一定的离子强度,此外, 由于 DNA 聚合酶同时具有外切酶活性,会影响酶切产 物,因此如下一步需进行克隆等操作,建议酶切前对 PCR 产物进行纯化。 

(3)本产品仅作科学研究使用,不得用于其它用途 

Restriction enzymes are a class of endonuclease enzymes that recognize specific sequences of deoxyribonucleotides and cut the phosphodiester bond between two deoxyribonucleotides at specific sites in each chain. BsaI is an IIS restriction enzyme that recognizes non-palindromic sequences and cuts sticky ends outside the recognition sequence.

Enzyme Activity Definition
The amount of enzyme required to fully digest 1 μg λDNA Dcm-HindIII fragments within 1 h in a 50 μl reaction system at 37℃ is defined as 1 activity unit (U).

Protocol
Example 1: DNA rapid enzyme digestion
(1) Configure the mixture as shown in the following table:

Component

(2) Gently mix, do not oscillate the vortex, and then instantaneous centrifugation.
(3) Reaction at 37℃ for 15 min (plasmid), or 15-30min (PCR product), or 30-60 min (genomic DNA).
(4) Reaction at 80℃ for 20 min can deactivate the enzyme and terminate the reaction (optional).

Cautions
(1) The methylation of Dcm, CpG and EcoB I will impair the cutting activity of this product.
(2) Unpurified PCR products have a certain ionic strength. In addition, since DNA polymerase also has exonuclidene activity, it will affect the enzyme digestion products. Therefore, cloning and other operations need to be performed in the following step.
(3) This product is for scientific research only and shall not be used for other purposes
