Abeta peptides are major components of neuritic plaques in Alzheimer's disease
Rabbit monoclonal recombinant IgG
Cat. No.: 218 108
Amount: 50 µg
Price: $420.00
Cat. No. 218 108 50 µg purified recombinant IgG, lyophilized. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.
Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications
 
WB: not tested yet
Dot blot: 1 : 1000 (AP staining) (see remarks) gallery  
IP: not tested yet
ICC: not tested yet
IHC: 1 : 500 up to 1 : 5000 (see remarks) gallery  
IHC-P: 1 : 1000 up to 1 : 4000 (see remarks) gallery  

Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunodetection of target molecules spotted onto a membrane.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Clone Rb2-48
Subtype IgG1 (κ light chain)
Immunogen Synthetic peptide corresponding to the amino terminal part of human Abeta-pE3 (UniProt Id: P05067)
Epitop AA 3 to 7 from human Abeta-pE3 (UniProt Id: P05067)
Reactivity Reacts with: human (P05067), mouse (P12023), rat (P08592), monkey.
Other species not tested yet.
Remarks

This antibody is a chimeric antibody based on the monoclonal mouse antibody 2-48. The constant regions of the heavy and light chains have been replaced with rabbit specific sequences. Therefore, the antibody can be used with standard anti-rabbit secondary reagents. The antibody has been expressed in mammalian cells.
Dot blot: This application was only tested with synthetic peptides. Please boil membrane for 3 minutes in PBS before blocking and antibody incubation.
IHC: Antigen retrieval with formic acid is required.
IHC-P: Antigen retrieval with citrate buffer pH 6, followed by formic acid treatment, is required for chromogenic detection.

Abeta-pE3-staining of plaques (red) in a transgenic APP/PS1 Alzheimer’s disease mouse brain section

Background

Amyloid deposits, also called plaques, of Alzheimer's patients consist of several protein components like the amyloid beta-peptides (Abeta, ) 1-40/42 and additional C- and N-terminally truncated and modified fragments. Very abundant are the isoaspartate (isoAsp)-Abeta and pyroglutamyl (pGlu)-Abeta peptides. The latter are formed by cyclization of the N-terminal glutamate at position 3 or 11 catalyzed by glutaminyl cyclase (QC) resulting in very amyloidogenic and neurotoxic variants of Abeta; Abeta-pE3 and Abeta pE11.
In contrast to extracellular plaques that do not perfectly correlate with Alzheimer´s disease intraneuronal Abeta accumulation and vascular Abeta deposits have gained more and more evidence to be among the crucial factors responsible for progressive neuron loss.
