Positivkontrolle:

Adult (24 months) mouse brain

3-month-old Taconic mouse Model 1349 brain fixed in 4% paraformaldehyde

Negativkontrolle:

We incubated slices overnight with the blocking solution only and then processed them with the secondary antibody.

Bewertung:

The beta amyloid antibody (Amyloid beta) (C-Term) ABIN5508784 works in IHC-P, especially at higher concentrations (1:200 and 1:500), and without the use of any antigen retrieval treatment.

Protokoll

Primärantikörper: ABIN5508784

Sekundärantikörper: goat anti-rabbit AF488-conjugated antibody (Invitrogen by Thermo Fisher Scientific, A11034, lot 1971418)

Full Protocol:

• Perfuse mice with paraformaldehyde 4% in 0.1 M phosphate buffer pH 7.4 and post-fix in the same fixative for an additional 2 h at RT.
• Wash, dehydrate, and embed samples in paraffin wax.
• Wash several times with 0.01 M PBS.
• Cut intestines and brain with a microtome into 6µm sections and mount on glass slides.
• After paraffin removal, incubate sections for 1 h at RT in PBS containing 1% albumin from chicken egg white (Sigma, A5378) and 0.3% Triton-X-100 (BioRad, 161-0407, lot 00583) to block non-specific binding sites.
• Incubate sections with primary anti-beta amyloid (C-Term) (antibodies Online, ABIN5508784, lot 190522A) diluted 1:200, 1:500, 1:1000, and 1:2000 in PBS-BSA-PLL ON at RT.
• Wash sections 3x 5 min with 0.01 M PBS.
• Incubate sections with secondary goat anti-rabbit AF488-conjugated antibody (Invitrogen by Thermo Fisher Scientific, A11034, lot 1971418) diluted 1:500 in 0.1 M PBS for 1 h at RT.
• Wash sections 3x 5 min with 0.01M PBS.
• Mount specimens in Fluoroshield (Sigma, F6182, lot MKCB0153V).
• Acquire images with a fluorescence microscope and appropriate filter settings for AF488, e.g. Leica DM 6000B fluorescence microscope equipped with a digital camera at 40x magnification.

Anmerkungen:

Antigen retrieval treatment was also tested. In this case, sections were processed for microwave antigen retrieval for 10 min(95-100 °C) in 10 mM sodium citrate buffer (pH 6.0). After 20 min of spontaneous cooling, sections were washed twice for 5 min with distilled water and for 5 min with PBS.

Details zu beta Amyloid

Target: beta Amyloid (Abeta) (Amyloid beta (Abeta))

Andere Bezeichnung: Amyloid beta (Abeta Produkte)

Hintergrund: Amyloid beta (Aβ or Abeta) is a peptide of 36 - 43 amino acids derived from the cleavage of APP (Amyloid Precursor Protein) by β- and γ-secretases. It is involved in Alzheimer´s disease, among other severe neurological disorders. It has been proved that the Aβ could be a crucial target for these important diseases treatment.
