GCaMP is a genetically encoded calcium indicator (GECI) which was created from a fusion of green fluorescent protein (GFP), calmodulin, and M13, a peptide sequence from myosin light chain kinase. GECI binds Ca2+ and induce a change in fluorescence signal, which allows measuring action potentials and other receptor activation events that trigger Ca2+ fluxes. The advantage of GECI's are that they can be genetically specified for studies in living organisms. The new novel GCaMP6 have increased ΔF/F0 and faster kinetics compared to previous GCaMP3 and GCaMP5G. This adenovirus expresses GCaMP6m.

Cas9 is the nuclease guided by the crRNA and tracrRNA (or trans-activating crRNA) to cleave specific DNA sequences. A guide RNA (gRNA) can be designed to include a hairpin that mimics the tracrRNA-crRNA complex. Binding specificity is based on the gRNA and a three nucleotide NGG sequence called the protospacer adjacent motif (PAM) sequence. With its ease in designing guide sequences to target specific genomic loci, the CRISPR/Cas system is a much simpler, faster, and robust alternative to TALEN and Zinc finger nuclease platforms. The main issue with Cas9 from Streptococcus pyogenes SF370 (SpCas9) is that this gene is too big to be packaged into AAV for most promoters, and there's no extra room for a sgRNA with the spCas9 in same AAV. A small Cas9 from Staphylococcus aureus subsp. aureus (SaCas9) with high efficiency for cleaving mammalian endogenous DNA becomes the ideal solution to package into AAV for effective gene modification in vivo. This is an AAV-DJ (a synthetic serotype made from 8 wild type AAV including AAV2, 4, 5, 8, 9) expressing spCas9 nuclease under a neuronal specific human synapsin 1 promoter. This AAV-hSYN-saCas9 can be package into other AAV serotypes upon request.We also offer custom AAV production service to package AAV-hSYN-saCas9 with your sgRNA in the same AAV virus.

This gene encodes retinoic acid receptor beta, a member of the thyroid-steroid hormone receptor superfamily of nuclear transcriptional regulators. This receptor localizes to the cytoplasm and to subnuclear compartments. It binds retinoic acid, the biologically active form of vitamin A which mediates cellular signalling in embryonic morphogenesis, cell growth and differentiation. It is thought that this protein limits growth of many cell types by regulating gene expression.

The immunophilins are a highly conserved family of cis-trans peptidyl-prolyl isomerases that bind to and mediate the effects of immunosuppressive drugs, such as cyclosporin, FK506 and rapamycin. Several related immunophilins, FKBP12, FKBP51 and FKBP52 are characterized as cytosolic FK506-binding proteins. Following ligand binding, they functionally inhibit the phosphatase activity of calcineurin. These related proteins have distinct molecular masses and differential expression patterns. FKBP12 and FKBP52 are both widely expressed and have molecular masses of 12 kDa and 52 kDa, respectively. FKBP51 is a 51 kDa protein that is predominantly expressed in T cells, where it blocks T cell activation.

A small Cas9 from Staphylococcus aureus subsp. aureus (SaCas9) with high efficiency for cleaving mammalian endogenous DNA becomes the ideal solution to package into AAV for effective gene modification in vivo. This is an AAV-DJ (a synthetic serotype made from 8 wild type AAV including AAV2, 4, 5, 8, 9) expressing spCas9 nuclease under a CMV promoter.

This AAV serotype 9 virus (with Capsid from AAV9 and ITR from AAV2) expresses Cre Recombinase and eGFP marker. Each gene expression is driven by its own CMV promoter.Cre recombinase is a Type I topoisomerase from P1 bacteriophage that catalyzes site-specific recombination of DNA between loxP sites. loxP is a 34 bp DNA sequence at which confers directionality. Cre recombinase is used as a tool to genetically modify genes, such as to delete a segment of DNA flanked by LoxP sites in cultured cells or experimental animals.

The protein encoded by this gene is a member of the MAP kinase family. MAP kinases act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is specifically activated by mitogen-activated protein kinase kinase 5 (MAP2K5/MEK5). It is involved in the downstream signaling processes of various receptor molecules including receptor type kinases, and G protein-coupled receptors. In response to extracelluar signals, this kinase translocates to cell nucleus, where it regulates gene expression by phosphorylating, and activating different transcription factors.

Cre recombinase is used as a tool to genetically modify genes, such as to delete a segment of DNA flanked by LoxP sites in cells or experimental animals. By applying the mammalian codon usage to Cre recombinase, expression of Cre is improved in the mammalian cells. This improved Cre (iCre) gene also reduce the high CpG content of the prokaryotic coding sequence, thereby reducing the chances of epigenetic silencing in mammals. This AAV-DJ/8 stock expresses an improved Cre (iCre) driven by one CMV promoter.

The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder.

Members of the Id family of basic helix-loop-helix (bHLH) proteins include Id1, Id2, Id3 and Id4. They are ubiquitously expressed and dimerize with members of the class A and bHLH proteins. Due to the absence of the basic region, the resulting heterodimers cannot bind DNA. The Id-type proteins thus appear to negatively regulate DNA binding of bHLH proteins. Id1 inhibits DNA binding of E12 and Myo D and inhibits muscle-specific gene expression. Under conditions that facilitate muscle cell differentiation, the Id protein levels fall, which allows E12 and/or E47 to form heterodimers with Myo D and myogenin to activate myogenic differentiation. Expression of each of the Id proteins is strongly dependent on growth factor activation. A reduction of Id mRNA levels by antisense oligonucleotides leads to a delayed re-entry of arrested cells into the cell cycle following growth factor stimulation.

T-cell factor (TCF-1) and lymphoid enhancer-binding factor (for LEF-1, also designated TCF-1(alpha)) compose a family of DNA-binding transcriptional activators that are essential for lymphoid cell development. These transcription factors are activated by the Wnt-1 and Wingless pathways and are characterized by the presence of a conserved protein motif, the high mobility group (HMG) 1 box, which mediates DNA binding. LEF-1, TCF-1, and two other family members, TCF-3 and TCF-4, directly bind to cytosolic beta-catenin and facilitate its translocation to the nucleus, where these complexes induce expression of Wnt target genes.

Genetic and biochemical studies have led to the identification of the Stat3-Interacting Protein STATIP1. The preferential association of STATIP1 with inactive (i.e., unphosphorylated) Stat3 suggests that it may contribute to the regulation of Stat3 activation. Overexpression of the Stat3-binding domain of STATIP1 blocks Stat3 activation, nuclear translocation, and Stat3-dependent induction of a reporter gene.
