Allograft Inflammatory Factor-1 (AIF-1, IBA1, IRT-1)

Allograft-inflammatory factor-1 (AIF-1) polypeptide, also known as Ionized calcium-binding adapter molecule 1, Iba-1. AIF-1 is a 17kD IFN-gamma inducible Ca2+-binding EF-hand protein, associated with chronic inflammatory processes. AIF-1 is constitutively expressed in lymphatic tissue and is up-regulated in monocytes/macrophages under various pathological conditions such as chronic rejection of allografts and in autoimmune lesions. In the brain, a subset of microglial cells constitutively express AIF-1. Increased numbers of AIF-1 immunoreactive macrophage/microglial cells were observed in focal brain infarctions, traumatic brain injury, gliomas, uveitis and in inflammatory lesions of a rat model of autoimmune disease, autoimmune encephalomyelitis and neuritis.\nSeveral Ca2+-binding peptides have been associated with monocyte activation, in particular members of the S-100 supergene-family. AIF-1 is a Ca2+-binding peptide which is not a member of the S-100 gene cluster but is located within the HLA class III genomic region.\n\nApplications:\nSuitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nImmunohistochemistry (Paraffin): 1:50. Antigen retrieval is recommended using a combination of microwave and a sodium citrate solution.\nWestern Blot: 1:50\nOptimal dilutions to be determined by the researcher.\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 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
