This product is the carrier-free version of product #17198. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.
This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN, or CUT&Tag assays. If you require a carrier-free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.
Supplied in 1X PBS, BSA and Azide Free.
For standard formulation of this product see product #17198.
Store at –20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.
Specificity / Sensitivity
Iba1/AIF-1 (E4O4W) XP® Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total Iba1/AIF-1 protein.
Human, Mouse, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala139 of human Iba1/AIF-1 protein.
Ionized calcium-binding adaptor molecule 1 (Iba1), also known as allograft inflammatory factor 1 (AIF-1), is an evolutionarily conserved cytoplasmic calcium binding protein containing a central pair of EF-hand calcium binding motifs (1,2). Iba1/AIF-1 was originally cloned from activated macrophages in human atherosclerotic allogenic heart grafts undergoing chronic transplant rejection as well as from rat monocytes (3,4). Its function is not very well understood, but Iba1/AIF-1 expression is upregulated in response to interferon-gamma and, therefore, could modulate macrophage-dependent immune response (3). As an F-actin-binding protein, Iba1/AIF-1 may function to remodel the actin cytoskeleton and contribute to morphological changes that correlate with various microglial/macrophage states (5). Iba1/AIF-1 is also uniquely expressed in cells of monocytic lineage and is, therefore, widely used as a marker for microglia/macrophages in the brain and other tissue (6).
