Recombinant Rat IL-15 (Legacy Tebubio ref. 167400-24). IL-15 is an immunomodulating cytokine that stimulates the proliferation of T lymphocytes and shares many biological properties with IL-2. IL-15 exerts its biological activities primarily on T cells. It is also essential in the development, survival and activation of NK cells. Increased expression of IL-15 has been linked to rheumatoid arthritis, inflammatory bowel disease, and diseases affiliated with retroviruses HIV and HTLV-I. Human IL-15 is biologically active on mouse cells as measured by the dose-dependent stimulation of the proliferation of mouse CTLL cells. Recombinant Rat IL-15 is a 13.5 kDa protein consisting of 115 amino acid residues.

Recombinant Rat Fractalkine (CX3CL1) (Legacy Tebubio ref. 167400-26). Fractalkine is a CX3CL chemokine that signals through the CX3CR1 receptor. Fractalkine has been shown to chemoattract monocytes, microglia cells and NK cells. Fractalkine is, at this time, the only CXC3C chemokine that contains three amino acid residues between the first and second cysteine residues of the chemokine domain. The Fractalkine gene encodes for a 397 amino acid precursor protein containing a 24 amino acid signal sequence, a chemokine domain, and a "mucin-like stalk" sequence, which is followed by the transmembrane domain containing approximately 20 amino acids, and a C-terminal cytoplasmic domain. The extracellular chemokine domain contains 76 amino acid residues, including the four conserved cysteine residues found in other chemokines. Recombinant Human Fractalkine is an 8.5 kDa protein containing 76 amino acid residues, including the four conserved cysteine residues present in CC chemokines. Recombinan

Recombinant Rat VEGF 165 (Legacy Tebubio ref. 167400-31). VEGF is a potent growth and angiogenic cytokine. It stimulates proliferation and survival of endothellial cells, and promotes angiogenesis and vascular permeability. Expressed in vascularized tissues, VEGF plays a prominent role in normal and pathological angiogenesis. Substantial evidence implicates VEGF in the induction of tumor metastasis and intra-ocular neovascular syndromes. VEGF signals through the three receptors; fms-like tyrosine kinase(flt-1), KDR gene product (the murine homolog of KDR is the flk-1 gene product) and the flt4 gene product. Recombinant Rat VEGF 165 is a 38.5 kDa, disulfide-linked homodimeric protein consisting of two 165 amino acid polypeptide chains.

Recombinant Rat SDF-1alpha (CXCL12) (Legacy Tebubio ref. 167400-32A). SDF-1alpha and beta are stromal-derived, CXC chemokines that signal through the CXCR4 receptor. SDF-1alpha and beta chemoattract B and T cells, and have been shown to induce migration of CD34+ stem cells. Additionally, the SDF-1 proteins exert HIV-suppressive activity in cells expressing the CXCR4 receptor. Human and murine SDF-1 proteins act across species. SDF-1alpha and beta contain the four highly conserved cysteine residues present in CXC chemokines. The mature SDF-1alpha protein is the result of alternative splicing of the SDF-1 gene and contains 68 amino acid residues. Recombinant Rat SDF-1alpha is a 7.9 kDa protein containing 68 amino acid residues.
