The production of the Alix monoclonal antibody begins with immunizing mice with recombinant human PDCD6IP protein. B cells from the spleen of the immunized mice are then fused with myeloma cells to generate hybridoma cells. The hybridoma cells are screened to identify the cell line that produces the Alix antibody. The Alix monoclonal antibody is purified from the mouse ascites using protein A affinity chromatography, resulting in a purity of over 95%. The antibody is an unconjugated IgG2b type and can be used in ELISA and WB applications to specifically recognize the human Alix protein.

Alix, also known as PDCD6IP, mainly functions in endosomal sorting and multivesicular body (MVB) biogenesis. Alix interacts with the endosomal sorting complex required for transport (ESCRT) machinery to mediate the sorting of ubiquitinated proteins into MVBs for degradation. Alix also plays a role in cytokinesis, virus budding, and apoptosis. It is involved in the regulation of intracellular calcium signaling and has been implicated in a variety of diseases, including cancer, HIV infection, and neurodegenerative disorders.

Target Background

Multifunctional protein involved in endocytosis, multivesicular body biogenesis, membrane repair, cytokinesis, apoptosis and maintenance of tight junction integrity. Class E VPS protein involved in concentration and sorting of cargo proteins of the multivesicular body (MVB) for incorporation into intralumenal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome. Binds to the phospholipid lysobisphosphatidic acid (LBPA) which is abundant in MVBs internal membranes. The MVB pathway requires the sequential function of ESCRT-O, -I,-II and -III complexes. The ESCRT machinery also functions in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis. Adapter for a subset of ESCRT-III proteins, such as CHMP4, to function at distinct membranes. Required for completion of cytokinesis. May play a role in the regulation of both apoptosis and cell proliferation. Regulates exosome biogenesis in concert with SDC1/4 and SDCBP. By interacting with F-actin, PARD3 and TJP1 secures the proper assembly and positioning of actomyosin-tight junction complex at the apical sides of adjacent epithelial cells that defines a spatial membrane domain essential for the maintenance of epithelial cell polarity and barrier.; (Microbial infection) Involved in HIV-1 virus budding. Can replace TSG101 it its role of supporting HIV-1 release; this function requires the interaction with CHMP4B. The ESCRT machinery also functions in topologically equivalent membrane fission events, such as enveloped virus budding (HIV-1 and other lentiviruses).
