More Info

  • Introduction

    Cas9 (CRISPR associated protein 9) is an RNA-guided DNA endonuclease enzyme associated with the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) adaptive immunity system in Streptococcus pyogenes, among other bacteria. S. Pyogenes utilizes Cas9 to remember and later probe and cleave foreign DNA, such as invading bacteriophage DNA or plasmid DNA. In case that the DNA substrate is complementary to the guide RNA, Cas9 cleaves the invading DNA. In addition to its original role in bacterial immunity, the Cas9 protein has been heavily employed as a genome engineering tool to induce site-directed double strand breaks in DNA. These disruptions may lead to gene inactivation or the presentation of heterologous genes via non-homologous end joining and homologous recombination respectively in many laboratory model organisms.

  • Synonyms

    CRISPR-associated endonuclease Cas9/Csn1, SpyCas9, cas9, csn1.

  • Physical Appearance

    Sterile Filtered colorless solution.

  • Stability

    Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.

  • Non-specific DNAse activity

    The incubation of 20pmol of CAS9 protein with 1µg of lambda DNA at 37°C for 4 hours is free of detectable DNA degradation, as visualized on agarose gel.

  • Enzymatic Activity

    97% of PCR product digestion after 30 minutes at 37°C.

  • Endonuclease Activity

    The incubation of 20pmol of CAS9 protein with 1µg pUC19 supercoiled vector at 37°C for 4 hours leads to formation of less than 10% open circular pUC19 form as determined by gel electrophoresis.
