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.

Background: HLA-DRB4 belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DRA) and a beta (DRB) chain, both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and its gene contains 6 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. DRB1 is expressed at a level five times higher than its paralogues DRB3, DRB4 and DRB5. The presence of DRB4 is linked with allelic variants of DRB1, otherwise it is omitted. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9. | ||||
