| Cat. No. HS-234 017BT |
100 µg purified IgG, lyophilized, labeled with Biotin.
Biotin is a small vitamin B complex molecule. Its small size minimizes interference with antibody binding sites and allows for efficient conjugation without compromising antibody functionality. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |

Staining of murine spleen section with biotinylated rat anti-IBA1
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).
