Description

Description générale

Accumulations of insoluble deposits/aggregates are the hallmarks of several neurodegenerative diseases. Deposits involving Aβ and tau proteins in Alzheimer′s disease (AD), α-synuclein (α-syn) in Parkinson′s disease (PD), prion protein (PrP) in prion diseases (PrD), TAR DNA-binding protein 43 (TDP-43) in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar dementia-TDP (FTLD-TDP) are well known examples. Evidence suggests that oligomers represent the more toxic species than fibrillar deposits in neurodegenerative conditions, such as AD, PD, and PrD. The number of Aβ deposits, for example, correlates poorly with disease progression, and many researchers consider them to be inert or even protective. Antibodies targeting beta-sheet oligomer conformations are being developed not only to study neurotoxic oligomers, but also for diagnostic and therapeutic purposes.

Spécificité

Clone F11G3 was raised against collodial gold particles coated with a synthetic peptide, Prp-G, whose sequence corresponds to an unstructured region of prion protein (Prp) with Met-to-Gly point mutations, as a beta-sheet oligomer mimetic (Guerrero-Muñoz, M.J., et al. (2013). ACS Chem. Neurosci. 4(12):1520-1523). Clone F11G3 recognizes oligomeric, but not monomeric or fibrillar, forms of Aβ42, α-syn, PrP, TDP-43, and polyQ Ataxin-1, as well as the misfolded oligomeric proteins in human AD brain samples (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558; Guerrero-Muñoz, M.J., et al. (2014). Neurobiol. Dis.71:14-23).

Target conformation is not species-specific.

Immunogène

Colloidal gold-conjugated Prp-G.

Application

Immunofluorescence Analysis: A representative lot specifically detected amyloid beta-sheet oligomer immunoreactivity in paraffin-embedded brain sections from Alzheimer′s diseased (AD), but not non-AD human brain by fluorescent immunohistochemistry (Courtesy of Dr. Rakez Kayed, University of Texas Medical Branch, Galveston, TX).

Western Blotting Analysis: A representative lot detected Ataxin-1 oligomers in soluble cerebella extracts from Atxn1154Q/+, but not wild-type or Atxn-/-, mice (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).

Western Blotting Analysis: A representative lot detected cellular beta-sheet oligomer immunoreactivity in HeLa cells transfected with the pathogenic (82Q), but not the non-pathogenic (30Q) form of polyQ Ataxin-1 in transfected Hela cells. Co-transfecting with the native Atxn-1 binding partner Capicua (CIC), but not the binding defective CIC W37A mutant, enhanced the oligomer formation (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).

Western Blotting Analysis: A representative lot detected the highest extend of oligomers accumulation in the soluble cerebella extracts among the 28-week old Atxn1154Q/+ mice when compared with samples from 18-week old and 8-week old Atxn1154Q/+ mice, with the 8-week old mice bearing the least oligomer buildup (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).

Western Blotting Analysis: A representative lot specifically detected oligomeric, but not monomeric or fibrillar, forms of Aβ42, α-Syn, PrP, and TDP-43 (Guerrero-Muñoz, M.J., et al. (2014). Neurobiol. Dis.71:14-23).

App3/DB/ A representative lot specifically detected oligomeric, but not monomeric or fibrillar, forms of Aβ42, α-Syn, PrP, and TDP-43 (Guerrero-Muñoz, M.J., et al. (2014). Neurobiol. Dis.71:14-23).

ELISA Analysis: A representative lot detected in vitro Aβ42, α-Syn, PrP, and TDP-43 oligomers formation with or without Aβ42 oligomer seeding (Guerrero-Muñoz, M.J., et al. (2014). Neurobiol. Dis.71:14-23).

Immunofluorescence Analysis: A representative lot detected a positive correlation between the ATXN1 beta-sheet oligomer immunoreactivity and the degeneration progression in calbindin-positive Purkinje cells (PCs) by fluorescent immunohistochemistry using paraffin-embedded cerebellum sections from Atxn1154Q/+ mice (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).

Immunofluorescence Analysis: A representative lot selectively detected beta-sheet oligomer immunoreactivity colocalized with those of Aβ, α-Syn, PrP, and TDP-43 in paraffin-embedded frontal cortex sections from Alzheimer′s diseased brain by fluorescent immunohistochemistry. The beta-sheet oligomer immunoreactivity is not detected in non-AD brains and is distinct from the staining pattern obtained with Thioflavin S (Guerrero-Muñoz, M.J., et al. (2014). Neurobiol. Dis.71:14-23).

Immunoprecipitation Analysis: A representative lot immunoprecipitated Ataxin-1 oligomers from the soluble cerebella extracts of Atxn1154Q/+, but not Atxn-/-, mice (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).

Immunocytochemistry Analysis: A representative lot detected cellular beta-sheet oligomer immunoreactivity in HeLa cells transfected with the pathogenic polyQ Ataxin-1 mRFP fusion construct mRFP-ATXN1(82Q) by fluorescent immunocytochemistry. Co-transfecting with the N-terminal fragment of the Atxn-1 binding partner Capicua (CIC), but not the binding defective CIC W37A mutant fragment, enhanced the oligomer formation (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).

Immunohistochemistry Analysis: A representative lot detected beta-sheet oligomer immunoreactivity in paraffin-embedded cerebellum and cortex sections of Atxn1154Q/+, but not wild-type, mice (Lasagna-Reeves, C.A., et al. (2015). eLlife. 4:e07558).
