50 µg purified recombinant IgG, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |
| Applications | |
| Clone | Hu311H9 |
| Subtype | IgG1 (κ light chain) |
| Immunogen | Synthetic peptide corresponding to residues near the carboxy terminus of rat IBA1 (UniProt Id: P55009) |
| Reactivity |
Reacts with: mouse (Q9EQW9), rat (P55009). Other species not tested yet. |
| Matching control protein/peptide | 234-0P |
| Remarks |
This antibody is a chimeric antibody based on the monoclonal mouse antibody 311H9. The constant regions of the heavy and light chains have been replaced with human specific sequences. Therefore, the antibody can be used with standard anti-human secondary reagents. The antibody has been expressed in mammalian cells. |

Ionized calcium-binding adaptor molecule 1 (IBA1) or allograft inflammatory factor1 (AIF-1) is an EF hand calcium binding protein which is expressed by cells of the monocyte/macrophage lineage and by germ cells in the testis (1). In mice, IBA1/AIF-1 can be regarded a “pan-macrophage marker” because, except for alveolar macrophages, all subpopulations of macrophages express IBA1/AIF-1 (1). In human gliomas IBA1 defines a distinct subset of tumor-associated activated macrophages/microglial cells (2).
Microglia represent the resident macrophages in the nervous system and are the smallest of the glial cells with cell bodies of only 2-5 µm in diameter. In the CNS IBA1 upregulation is associated with neuroinflammatory response (3).
