Cas9 Nuclease 
Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide bacteria and archaea with adaptive immunity against viruses and plasmids by using CRISPR RNAs (crRNAs) to guide the silencing of invading nucleic acids. The CRISPR system consists of a short non-coding guide RNA (sgRNA) made up of a target complementary CRISPR RNA (crRNA) and an auxiliary transactivating crRNA (tracrRNA). The sgRNA guides the Cas9 endonuclease to a specific genomic locus via base pairing between the crRNA sequence and the target sequence, and cleaves the DNA to create a double-strand break. The location of the break is within the target sequence 3 bases from the NGG PAM (Protospacer Adjacent Motif). The PAM sequence, NGG, must follow the targeted region on the opposite strand of the DNA with respect to the region complementary sgRNA sequence

Intact Genomics Cas9 Nuclease is the purified recombinant Streptococcus pyogenes Cas9 enzyme containing a nuclear localization signal (NLS) at the C-terminal for targeting to the nucleus. This enzyme is designed to perform CRISPR/Cas9-mediated genome editing. The physical purity of this enzyme is â¥98% as assessed by SDS-PAGE with Coomassie® blue staining.

Quality Control 
Quality control is performed following the production of each new lot of product to ensure that it meets the quality standards and specifications designated for the product. Each lot is repeatedly compared side-by-side with leading competitors to ensure our products outperform the competitor before product launching. 

Cas9 nuclease is free from detectable RNase, Endonuclease (nicking) and non-specific DNase activities.

HS Taq Polymerase Master Mix BLUE is a ready to use 2 X master mix. Simply add primers, template and water to successfully carry out primer extensions. The master mix is available in 100, 500, 1000, and 2500 reaction sizes and is available with two different buffer options (HS Buffer 1 and HS Buffer 2)


HS Taq Polymerase is a modified form of Bullseye Taq, activated by heat treatment. This results in higher specificity and greater yields when compared to standard Taq. The added benefit of the HS Master Mix Blue is that it can be loaded directly onto the gel as there is no need to use separate loading dyes for subsequent electrophoresis and visualization. This cuts down on the chance of contaminating the component stocks and leads to better reproducibility.

Composition of 2 X HS Master Mix Blue with Buffer 1
Tris-HCl, pH 8.5, (NH4)2SO4,3 mM, MgCl2, .2 % Tween 20, .4 mM dNTPs, .2 units/uL HS Taq Polymerase, Inert Blue Dye, Stabilizer

Composition of 2 X HS Master Mix Blue with Buffer 2
Tris-Hcl, pH 8.5, Balanced KCl/(NH4)2SO4,3 mM, MgCl2, .2 % Tween 20, .4 mM dNTPD, .2 units/uL HS Taq Polymerase, Inert Blue Dye, Stabilizer
