  Protein G, a cell surface protein of group G streptococci, is a Type III Fc receptor that binds to the Fc region of IgG by a non-immune mechanism similar to that of protein A from Staphylococcus aureus. This product contains three IgG binding domains, but its albumin-binding region has been removed. Additionally, His-tag and cysteine have been added to N- and C-termini, respectively, to facilitate purification and conjugation. This does not affect the protein's ability to bind to IgG.

• 描述
  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.

• 描述
  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.

  Tobacco Etch Virus Protease is a highly site-specific cysteine protease that is found in the Tobacco Etch Virus (TEV). The optimum recognition site for this enzyme is the sequence Glu-Asn-Leu-Tyr-Phe-Gln-(Gly/Ser) [ENLYFQ(G/S)] and cleavage occurs between the Gln and Gly/Ser residues, The most commonly used sequence is ENLYFQG. The protease is used to cleave affinity Tobacco Etch Virus Protease (rTEV) contains 231 amino acids with N-terminal His tagged. A fully biologically active molecule, rTEV has a molecular mass of 28.4 kDa and is obtained by proprietary chromatographic techniques at GenScript.

• 描述
  GenCrispr NLS-Cas9-EGFP is a fusion protein developed by GenScript. It contains a nuclear localization signal (NLS) on its N terminal end, and an EGFP and a 6x(His) sequence on the C terminal end. Cas9 nuclease is an RNA-guided endonuclease that can catalyze cleavage of double stranded DNA. This kind of targeted nuclease is a powerful tool for genome editing with high precision. Cas9 protein forms a highly stable ribonucleoprotein (RNP) complex with the guide RNA (gRNA) component of the CRISPR/Cas9 system. When Cas9 is expressed with an NLS sequence, the Cas9 RNP complex can localize to the nucleus immediately upon entering the cell. There is no requirement for in vivo transcription or translation, which improves the efficiency of this method over plasmid-based systems. Additionally, the Cas9 RNP complex is rapidly cleared from the cells minimizing the chance of off-target cleavage when compared to other systems (Kim, et al. 2014). The EGFP tag can be used as a reporter for tracking or sorting transfected cells, which enables enrichment of cell populations for desired genome edits via fluorescence activated cell sorting (FACS). It significantly reduces the labor and cost associated with single cell cloning and genotyping in genome editing applications.
