NewEast Biosciences pioneered the research and development of the antibodies for GTPases and mutated Oncogene ten years ago. GTPases involve (1) signal transduction in response to activation of cell surface receptors, including transmembrane receptors such as those mediating taste, smell and vision, (2) protein biosynthesis at the ribosome, (3) regulation of cell differentiation, proliferation, division and movement, (4) translocation of proteins through membranes, (5) transport of vesicles within the cell, and vesicle-mediated secretion and uptake, through GTPase control of vesicle coat assembly. An oncogene is a gene that has the potential to cause cancer.
We offer three unique categories of antibodies, which (1) recognize only the active configuration of GTPase (not the inactive one), (2) mutated Oncogene (not mild type) and (3) have super affinity for cAMP and cGMP (no acetylation required). We have over one thousand peer reviewed articles cited our products.

Description: Recombinant Human Interleukin-15 Receptor Alpha and Interleukin-15 Fusion Protein Complex is produced by our Mammalian expression system and the target gene encoding Ile31-Asp96andAsn49-Ser162 (Asn120Asp) is expressed with a Fc tag at the C-terminus. |
Background: IL15RA is a high-affinity receptor for interleukin-15. Il15ra associates as a heterotrimer with the IL-2 receptor beta and gamma subunits to initiate signal transduction. It can signal both in cis and trans where IL15R from one subset of cells presents IL15 to neighboring IL2RG-expressing cells. Il15ra is expressed in special cells including a wide variety of Tand B cells and non-lymphoid cells.IL-15 is a cytokine that regulates T cell and natural killer cell activation and proliferation. IL-15 binds to the alpha subunit of the IL-15RA with high affinity. IL-15 also binds to the beta and gamma chains of the IL-2 receptor, but not the alpha subunit of the IL2 receptor. IL-15 is structurally and functionally related to IL-2. Both cytokines share some subunits of receptors, allowing them to compete for and negatively regulate each other's activity. The number of CD8 memory T cells is controlled by a balance between IL-15 and IL-2. Despite their many overlapping functional properties, IL-2 and IL-15 are, in fact, quite distinct players in the immune system. IL-15 is constitutively expressed by a wide variety of cell types and tissues, including monocytes, macrophages and DCs. The enhanced activity of the IL-15N72D:IL-15RaSu/Fc complex is likely the result of the increased binding activity of IL-15N72D to IL-15Rβγ c , optimized cytokine trans-presentation by the IL-15RaSu domain, the dimeric nature of the cytokine domain and its increased in vivo half-life compared to IL-15. These findings indicate that this IL-15 superagonist complex could serve as a superior immunostimulatory therapeutic agent. |
