Keep at -20°C
Working Concentration: 1 ~ 2 µg/mL (Immunocytochemistry)
Anti Iba-1 polyclonal antibody, Rabbit, for Western Blotting

Calcium ions are known to be one of the most important signal mediators in all cells including
central nervous system (CNS) cells. Calcium ions exert their signaling activity through
association with various calcium binding proteins, many of which are classified into a large
protein family, the EF hand protein family.
Iba1 is a 17-kDa EF hand protein that is specifically expressed in macrophages/ microglia
and is upregulated during the activation of these cells.
Wako distributes rabbit polyclonal antibodies were raised against a synthetic peptide
corresponding to the Iba1 carboxy-terminal sequence, which was conserved among human,
rat and mouse Iba1 protein sequences. These antibodies are specifically reactive to
microglia/ macrophages, are appropriate for immuno-double staining of brain tissues and cell
culture in combination with monoclonal antibody to GFAP, which specifically reacts to astrocyte.

Specific to microglia and macrophages, but not cross-reactive with neurons and astrocytes. Reactive with human, mouse and rat Iba1.

Research for Olfactory Nerve
Anti Olfactory Marker Protein, Goat [Anti OMP]
Wako Cat. No. 019-22291* (100 µL) <for Immunochemistry>
Keep at -20°C
*: The catalog number was used to be 544-10001.
Olfactory Marker Protein (OMP) is soluble acid protein expressed in mature olfactory nerve. This goat antiserum is highly specifi c for mature olfactory neurons and their axons and terminals in tissue sections of many vertebrate species including rodents, humans, marsupials and amphibia.
Working Dilutions:
Western Blot: ~ 1 : 50,000
Immunocytochemistry: 1 : 200 (paraffin embedded material)
1 : 50,000 (Vectastain-Elite with fixed floating sections)
Goat antiserum to OMP (100 μL) is diluted 1:1 with glycerol containing 0.05% sodium azide to facilitate shipment at ambient temperature.
