Amyloid Oligomers (A11) Antibody

Amyloid Oligomers (A11) Antibody is a rabbit polyclonal antibody directed against Amyloid Oligomers (A11), offered by Assay Genie for research applications. Reported applications include WB, IHC, ICC/IF, IP and ELISA. Reported reactivity: Human, Mouse, Rat and Eukaryote. Purified by Protein A.

Amyloid oligomers are soluble, misfolded protein assemblies that represent a critical early stage in the formation of amyloid fibrils. Detected by the conformation-specific A11 antibody, these oligomeric species are increasingly recognized as the most neurotoxic form of amyloid aggregates in neurodegenerative diseases. Unlike mature fibrils, amyloid oligomers disrupt cellular function through membrane permeabilization, oxidative stress, and synaptic impairment. Oligomerization can occur even in non-disease-related proteins under conditions of partial misfolding or denaturation, highlighting the intrinsic amyloidogenic potential of many polypeptides. In pathological contexts, amyloid oligomers are central to the progression of disorders such as Alzheimer’s disease (via amyloid-β and tau), Parkinson’s disease (via α-synuclein), and Huntington’s disease (via polyglutamine-expanded huntingtin). These toxic intermediates precede the formation of insoluble plaques and tangles, making them valuable biomarkers and therapeutic targets. The A11 antibody has become a powerful tool in neuroscience research, enabling the selective detection of prefibrillar oligomers across diverse amyloidogenic proteins. Its application has advanced our understanding of early aggregation events and their role in synaptic dysfunction and neuronal loss. As the field shifts toward early intervention strategies, amyloid oligomers—and their detection via A11—are at the forefront of neurodegenerative disease research, offering critical insights into disease mechanisms and potential avenues for therapeutic development. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µl.
