This antibody is specific for endogenous levels of the ~32 kDa fractin protein and shows no reactivity toward intact actin. There is often a ladder of smaller bands in cells or culture or in-vivo preparations due to further degradation by other proteases. In IHC, the antibody detects the processes and cell bodies of degenerating neurons and plaque-associated microglia in Alzheimer's disease.
Fractin (fragment of actin) is a caspase-specific cleavage product of actin and serves as a novel marker of apoptosis-related events. It has recently been reported that fractin may have a functional role in apoptotic signaling in oligodendrocytes (Schulz, R., et al., Glia, 2009).
