Product Specific Information
Store vial at 4°C prior to restoration. For extended storage, aliquot contents and freeze at -20°C or below. Avoid cycles of freezing and thawing.
Centrifuge product if not completely clear after standing at room temperature.
This product is stable for several weeks at 4°C as an undiluted liquid. Dilute only prior to immediate use.
Anti-Cas9 antibody is directed against Streptococcus pyogenes Cas9.
Target Information
Cas9 is an RNA-guided DNA endonuclease enzyme associated with the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) adaptive immunity system in bacteria and genetic engineering.
The system is unique and flexible due to its dependence on RNA as the element that targets the nuclease to a desired DNA sequence.
It can be used to induce indel mutations, specific sequence replacements/insertions, and large deletions or genomic rearrangements at any desired location in the genome.
In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation.
Cas9 may be derived from Streptococcus pyogenes (SpCas9) or Staphylococcus aureus (SaCas9).
SaCas9 has a number of properties that make it advantageous for genome editing, including its small size, high efficiency, nickase activity, and apparent specificity.
SaCas9 principally recognizes an NNGRRT protospacer adjacent motif (PAM) and cleaves target DNA at rates comparable to SpCas9 with ideal spacer lengths of 24 to 20 nucleotides.
In comparison to SpCas9, SaCas9 is smaller (1368 AA versus 1053 AA) and generates indels at a comparable rate when directed against target DNA with the mutually permissive NGGRRT PAM.
This makes it the preferred enzyme for all-in-one delivery of Cas9 and multiple gRNA expression cassettes with Adeno-associated vectors.
