Background Information
IBA1 is a 143 amino acid cytoplasmic, inflammation response scaffold protein. It is constitutively expressed in monocytes and macrophages and is known to be involved in macrophage activation. It is a marker of activated macrophage. Expression of IBA1 is up-regulated in activated microglia following facial nerve axotomy, ischemia, and several brain diseases, thereby implicating it in the activated phenotypes of microglia.

Reviews
What customers say
Customer feedback is mixed. One user (5/5) reported excellent immunofluorescence staining in iPSC-derived macrophages and microglia at 1:500 dilution for confocal microscopy. Another user (2/5) noted a problematic result in Western blot on postmortem human frontal cortex tissue at 1:1000 dilution, observing a clear band at 25 kD that did not correspond to the expected molecular weight. Overall, the antibody performs well for IF applications but may show non-specific or incorrect molecular weight bands in WB.
