Vector Biolabs STAT3 interacting protein 1 Adenovirus (Ad-STAT3IP)
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.
New England Biolabs, Inc. pTWIN1 Vector DNA – 10 µg
pTWIN1 is an E. coli expression vector designed for protein purification or for the isolation of proteins with an N-terminal cysteine and/or a C-terminal thioester. A polylinker in the vector is designed for the in-frame fusion of a target gene between the modified Ssp DnaB and Mxe GyrA inteins. The presence of the chitin binding domain from Bacillus circulans facilitates purification.
Vector Biolabs BCL2-related protein A1 Adenovirus (Ad-Bcl2A1)
This gene encodes a member of the BCL-2 protein family. The proteins of this family form hetero- or homodimers and act as anti- and pro-apoptotic regulators that are involved in a wide variety of cellular activities such as embryonic development, homeostasis and tumorigenesis. The protein encoded by this gene is able to reduce the release of pro-apoptotic cytochrome c from mitochondria and block caspase activation. This gene is a direct transcription target of NF-kappa B in response to inflammatory mediators, and has been shown to be up-regulated by different extracellular signals, such as granulocyte-macrophage colony-stimulating factor (GM-CSF), CD40, phorbol ester and inflammatory cytokine TNF and IL-1, which suggests a cytoprotective function that is essential for lymphocyte activation as well as cell survival.
New England Biolabs, Inc. pMAL™-c6T Vector – 50 µl
The pMAL-c6T Vector is designed to produce maltose-binding protein (MBP) fusions in the cytoplasm. The MBP has been engineered for tighter binding to amylose resin. The vector expresses an N-terminal his-tagged malE gene followed by a multiple cloning site containing a TEV protease recognition sequence, allowing MBP to be cleaved from the protein of interest after purification.

Vector Biolabs Endothelin 1 Adenovirus (Ad-ET-1)
The endothelins are family of cysteine-rich peptides consisting of 21-amino acid and containing two intramolecular disulfide bridges that exert their vasoactive and mitogenic actions through G protein-coupled receptors. At the present, the existence of three active isoforms of ET (-1, -2, and -3), and two distinct receptors, ETA and ETB, is well documented (17). The active form of ET-1 arises from biologically inactive big-ET-1 through the action of a specific protease that removes 18 amino acids from its carboxyl terminal. This membrane-bound metallopeptidase, characterized by its sensitivity to phosphoramidon, is known as endothelin-converting enzyme-1 (ECE-1) . A growing body of evidence indicate that ET-1 is a major player in numerous disease states including congestive heart failure, pulmonary fibrosis, obesity and diabetes, as well as a key mediator of tissue repair and normal wound healing.
Vector Biolabs Aurora kinase A Adenovirus (Ad-Aurora-A)
Aurora related kinase-1 (ARK-1, STK15, STK6, Aurora2) and -2 (ARK-2, STK12, Aurora1) are centrosome-associated serine/threonine kinases that regulate centrosome separation, bipolar spindle assembly and chromosome segregation during mitosis. First characterized in human colorectal cancers, ARK-1 and -2 are closely related to Drosophila aurora kinases. ARK-1 protein has elevated expression in colon carcinoma lines (HT-29, SNU-C2B, COLO 205, SW480, 837 and 948) and accumulates during metaphase in HeLa cells. ARK-1 and -2 have unique genetic loci, suggesting that these two kinases, with oncogenic potential, play different roles in cell cycle progression.
Vector Biolabs Zeta-chain (TCR) associated protein kinase 70kDa Adenovirus (Ad-ZAP-70)
Syk p72 and ZAP-70 resemble the Src family protein tyrosine kinases in that they have a C-terminal catalytic domain, but differ in that they are characterized by two SH2 domains but no SH3 domains. Syk p72 kinase fused to the transmembrane and extracellular domains of CD7 and CD16, respectively, can induce complete T cell activation, implying the involvement of the Syk/ZAP family proteins in T cell activation. In contrast, the ZAP-70 kinase is insufficient for complete T cell activation unless it is coaggregated with a Fyn p59-containing chimera, suggesting that regulation of ZAP-70 activity may require a functional interaction with Src family kinases.
New England Biolabs, Inc. PhiX174 RF II DNA – 150 µg
This commonly used cloning vector is the double-stranded nicked circular form of ΦX174 - relaxed form. Its molecular weight is 3.5 x10^6 Daltons and it is 5,386 base pairs in length. Greater then 90% of the molecules are RF II, the remainder are RF I (supercoiled) and linear ΦX174 DNA.
New England Biolabs, Inc. pTXB1 Vector – 10 µg
pTXB1 is an E. coli expression vector designed for the in-frame insertion of a target gene into the polylinker upstream of the Mxe intein/chitin binding domain. The fusion protein is bound to chitin beads and the thiol-induced cleavage activity of the intein releases the target protein.

IBA LifeSciences StrGate Acptr Vctr pCSG-IBAwt2
pCSG-IBAwt2 is a large expression vector with universal features for transient expression as well as for generation of stable mammalian cell lines. The vector carries an ampicillin resistance cassette for selection of transformed E. coli cells and ColE1 origin for a high plasmid copy number. Extrachromosomal replication in mammalian cells could occur either by origin of replication from Epstein-Barr Virus (oriP) or by SV40 ori. For the former the vector provides the EBNA-1 gene and for the latter the cell line has to be latently infected with SV40 or express the SV40 large T antigen (e.g. HEK293T, COS-1, COS-7). Stable cell lines can be selected by the neomycin resistance gene (NeoR). In addition, the human cytomegalovirus (CMV) immediate-early promoter enables a high-level expression. During translocation from the cytosol the signal peptide is removed from the protein by endogenous proteases.
Vector Biolabs vascular endothelial growth factor D Adenovirus (Ad-VEGF-D)
The onset of angiogenesis is believed to be an early event in tumorigenesis and may facilitate tumor progression and metastasis. Several growth factors with angiogenic activity have been described. These include FGF, PDGF, vascular endothelial growth factor (VEGF), VEGF-B, VEGF-C, VEGF-D (or FIGF), EG-VEGF and placenta growth factor (PlGF). VEGF-D undergoes a complex proteolytic maturation, generating multiple processed forms which bind and activate VEGFR-2 and VEGFR-3 receptors. This protein is structurally and functionally similar to vascular endothelial growth factor C.
Vector Biolabs cAMP responsive element binding protein 1 Adenovirus (Ad-CREB1)
The ATF/CREB family consists of a series of transcription factors that function by binding to the cAMP responsive element (CRE) palindromic octanucleotide, TGACCTCA. The best characterized members of this gene family include CREB-1, CREB-2, LZIP (also designated CREB3 and Luman), CREM-2, ATF-1, ATF-2, ATF-3, ATF-4, ATF-6 and ATF-7. These transcription factors share terminal leucine zipper dimerization and basic DNA binding domains and are highly variable in their N-termini. Although each of the ATF/CREB proteins bind CREs in their homodimeric form, they can also bind as heterodimers, both within the ATF/CREB family and with members of the AP-1 transcription factor family. Protein kinase A-mediated CREB phosphorylation induces association with a 265 kDa nuclear protein designated CBP (CREB-binding protein), which may represent a CREB coactivator.
