UNC93B1 (Protein Unc-93 Homolog B1, Unc-93B1, hUNC93B1, UNC93, UNC93B)

The endoplasmic reticulum (ER) protein Unc93b, a human homolog of the C. elegans Unc93 gene, was initially identified by a forward genetic screen using N-ethyl-N-nitrosourea where a histidine-to-arginine substitution in Unc93b caused defects in Toll-like receptor (TLR) 3, 7 and 9 signaling. Unlike Unc93a, another homolog of the C. elegans Unc93 gene whose function is unknown, Unc93b specifically interacts with TLR3, 7 and 9; the histidine-to-arginine point mutation used to identify Unc93b abolishes this interaction. Mice carrying this point mutation are highly susceptible to infection with a number of viruses, indicating that Unc93b plays an important role in innate immunity. Multiple isoforms of Unc93a are known to exist. This antibody will not cross-react with Unc93a.\n\nApplications:\nSuitable for use in ELISA, Western Blot, Immunofluorescence and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 0.5-1ug/ml\nImmunofluorescence: 20ug/ml\nImmunohistochemistry (Formalin fixed paraffin embedded): 2.5ug/ml\nOptimal dilutions to be determined by the researcher.\n\nPositive Control:\nHuman Heart Tissue Lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
