The
clustered regularly interspaced short palindromic repeats, known as CRISPR  systems are adaptive immune mechanisms commonly
present in archaea and bacteria. The CRISPR systems enable the host to specifically
target and cleave foreign nucleic acids thus targeting infectiousviruses and
plasmids. Recently, a type V CRISPR system has been identified in several
bacteria, the Cpf1 CRISPR from Prevotella and Francisella 1. In contrast to
Cas9 systems, CRISPR/Cpf1 systems are smaller in size, do not require an
additional trans-activating crRNA (tracrRNA), and allow for targeting of
additional genomic regions by cleaveing the target DNA proceeded by a short
T-rich protospacer-adjacent motif (PAM). On the other hand, the Cas9 system requires
a G-rich PAM following the target DNA. Furthermore, Cas12a/Cpf1 introduces a
staggered DNA double stranded break with a 4 or 5-nt 5’ overhang. Recombinant
Acidaminococcus sp. BV3L6 Cas12a (cpf1) nuclease is expressed in E. coli and
purified. The nuclease contains nuclear localization sequence (NLS) at the
C-terminus and 6× His-tag at the C-terminus.

GenCRISPR Cas13a (C2c2) Nuclease is an RNA-guided, RNA-targeting CRISPR enzyme, commonly referred to as C2c2. This enzyme is a member of Type VI CRISPR family containing a single protein effector with two HEPN domains. The Cas13a exhibits two RNase activities. The first activity, a cis- sequence-specific RNA guided cleavage, activates the secondary RNase activity of the enzyme, a non-specific trans- ribonuclease activity. This Cas13a protein can be applied to detect single RNA molecules with proven high specificity.

The GenCRISPR™
Cas9 v1.1 can be formed
with the guide RNA into a ribonucleoprotien (RNP) complex. The use of an RNP
complex to perform gene editing has been shown to reduce the challenges
encountered with other CRISPR gene editing techniques such as viral and plasmid
delivery. Challenges include off-target effects, cell viability and transcription/translational
challenges.

GenCRISPR™
Cas9 v1.1 is a tag free nuclease produced by expression in an E. coli strain carrying a plasmid
encoding the Cas9 gene from Streptococcus
pyogenes with a biparticle nucleus localization signal (BPNLS) at both
N-terminal and C-terminal. It has been reported that BPNLS is able to improve
the gene editing efficiency.

The GenCRISPR™
Cas9 v1.2 can be formed
with the guide RNA into a ribonucleoprotien (RNP) complex. The use of an RNP
complex to perform gene editing has been shown to reduce the challenges
encountered with other CRISPR gene editing techniques such as viral and plasmid
delivery. Challenges include off-target effects, cell viability and transcription/translational

GenCRISPR™ Cas9 v1.2 is a tag
free nuclease produced by expression in an E.
coli strain carrying a plasmid encoding the Cas9 gene from Streptococcus pyogenes with a biparticle
nucleus localization signal (BPNLS) at N-terminal and a nucleoplasmin nucleus
localization signal (nucleoplasmin NLS) at C-terminal. It has been reported
that BPNLS and nucleoplasmin NLS are able to improve the gene editing
efficiency. 

GenCRISPR™ ErCas12a Nuclease is an RNA-guided DNA endonuclease from Eubacterium rectale. It recognizes a T-rich protospacer adjacent motif (PAM) and results in a staggered DNA double-strand break (DSB). After the specific cleavage, Cas12a can also activate collateral cleavage activity towards adjacent non-specific ssDNA sequences. Hence, Cas12a nuclease is a good alternative for Cas9 in certain target DNA editing, and provides a novel strategy for DNA detection.

GenCRISPR™ LbCas12a Nuclease is an RNA-guided DNA endonuclease from Lachnospiraceae bacterium. Cas12-family enzymes exhibit two DNase activity modes; besides crRNA-guided cis-cleavage of cDNA targets, these nucleases also catalyze trans-cleavage of non-target ssDNA substrates introduced by target DNA, which has been exploited to develop sensitive technologies for nucleic acid detection.

GenCRISPR™ LbuCas13a Nuclease is an RNA-guided, RNA-targeting CRISPR enzyme, commonly referred to as LbuC2c2. This Cas13a protein can be applied to detect single RNA molecules with proven high specificity. Recently, Cas13a has been leveraged as a diagnostic nucleic acid detection tool.

GenCRISPR™ Ultra eSpCas9-2NLS-basic GMP is utilized for CRISPR gene editing applications. The Cas9 nuclease forms a stable ribonucleoprotein (RNP) complex with the guide RNA (gRNA) component. With the help of two nuclear localization signals (NLS) expressed with the Cas9 nuclease, the RNP complex enters the nucleus and cleaves target gene. When compared with a plasmid-based delivery system, the RNP delivery system has been observed to increase the on-target gene editing efficiency and decrease off-target effects.

GenCRISPR™ Ultra NLS-Cas9-basic GMP is utilized for CRISPR gene editing applications. The Cas9 nuclease forms a stable ribonucleoprotein (RNP) complex with the guide RNA (gRNA) component.
