Product details:
This antibody was developed as part of a collaboration between Abcam and Professor Charles Glabe, UC Irvine.
ab205341 (mOC78) recognizes a conformation-dependent and aggregation-specific discontinuous epitope of beta Amyloid that maps to segments 8-11 (SGYE), 18-24 (VFFAEDV) and 26-32 (SNKGAII) (Hatami et al. 2014, PMID: 25281743). It also recognizes a-synuclein and islet amyloid polypeptide (IAPP) fibrils but not monomers on dot blots. It recognizes a broad range of bands from monomer to high molecular weight with samples of Aß40 and Aß42 on western blots (Hatami et al. 2014, PMID: 25281743). Immunoreactivity on western blots is not changed by boiling the membrane. mOC78 stains plaques and a unique population of intraneuronal and intranuclear amyloid and also stains the center of nascent neuritic plaques where it colocalizes with neuronal chromatin (Pensalfani et al 2014, PMID: 25092575).

Amyloid fibrils alternatively named fibrillar amyloid are insoluble fibrous protein aggregates resulting from the abnormal folding of proteins. They compose primarily of beta-sheet structures which promote stability and rigidity. Amyloid fibrils are frequently associated with proteins like Aβ and tau known for their high molecular mass. Researchers observe these structures in various tissues where they exhibit significant resilience to both chemical and enzymatic degradation.
Biological function summary
The misfolding and accumulation of proteins into amyloid fibrils prove disruptive within cells. These aggregates often form as part of complex protein assemblies and interfere with normal cellular functions. This disruption further leads to cellular dysfunction and death. While commonly observed in neuronal cells where they are linked to neurodegenerative conditions amyloid fibrils can also appear in other tissues and organs suggesting multi-systemic implications.
Pathways
Scientists recognize amyloid fibrils for their involvement in the amyloidogenic pathways. These pathways often lead to the generation and accumulation of misfolded proteins. The amyloid precursor protein (APP) and presenilins play important roles in pathway processes associated with amyloid fibrils. In addition the fibrillar structures can influence calcium dysregulation and oxidative stress contributing to altered cellular homeostasis.
Amyloid fibrils are strongly associated with Alzheimer's disease and systemic amyloidosis. Within Alzheimer's disease amyloid fibrils formed by Aβ peptides contribute to plaque formation a hallmark of the condition. Furthermore interactions with tau protein exacerbate neurofibrillary tangles compounding neurodegenerative effects. In systemic amyloidosis different precursor proteins undergo fibrillogenesis resulting in widespread organ dysfunction and highlighting the pathogenic potential of amyloid fibrils beyond neurological tissues.
