Immunogen: Cas-9 affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a region near the C-terminal of Streptococcus pyogenes Cas-9 protein.
Immunogen Type: Peptide
Synonyms: CRISPR, CRISPR-associated endonuclease Cas9/Csn1, SpyCas9, csn1, Cas-9 Antibody
Background: The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR Associated (Cas) system was discovered in bacteria as a defense against foreign DNA, even being believed to act as a sort of prokaryotic immune system. The Cas9 protein is becoming a a useful tool in the field of genomic editing for its ability to induce site-directed double strand breaks in DNA. It can cleave almost any sequence complementary to the guide RNA and has recently been used for modifying the genome of human embryos for the first time.
Gene Name: cas9
Application Note: This affinity purified antibody has been tested for use in ELISA, Immunofluorescence, and Western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band ~158 kDa in size corresponding to Cas-9 protein by western blotting in the appropriate cell lysate or extract.
Western Blot Dilution: 1:1000
ELISA Dilution: 1:25,000-1:30,000
IF Microscopy Dilution: 1 μg/mL
Buffer: 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2
