Beta Amyloid Antibody

ELISA results of purified Rabbit anti-Beta Amyloid Antibody tested against BSA-conjugated peptide of immunizing peptide. Each well was coated in duplicate with 0.1 µg of conjugate. The starting dilution of antibody was 5 µg/ml and the X-axis represents the Log10 of a 3-fold dilution. This titration is a 4-parameter curve fit where the IC50 is defined as the titer of the antibody. Assay performed using 3% fish gel, Goat anti-Rabbit IgG Antibody Peroxidase Conjugated (Min X Bv Ch Gt GP Ham Hs Hu Ms Rt & Sh Serum Proteins) (p/n orb347654) and TMB ELISA Peroxidase Substrate (p/n orb348651).

Human Heart (formalin-fixed, paraffin-embedded) stained with Anti-Beta Amyloid Antibody at 5 ug/ml followed by biotinylated goat anti-rabbit IgG secondary antibody, alkaline phosphatase-streptavidin and chromogen.

Immunofluorescence microscopy of Rabbit Anti-Beta Amyloid antibody using HeLa cells fixed with MeOH. Anti-Beta Amyloid Antibody was used at 1 µg/ml, O/N at 4°C. Secondary antibody: Anti-RABBIT IgG DyLight™ 488 Conjugated Preadsorbed at 2 ug/ml for 1 h at RT. Localization: APP is a cell surface protein that rapidly becomes internalized to endosomes and lysosomes. Some APP accumulates in secretory transport vesicles. Colocalizes with other proteins in a vesicular pattern in cytoplasm and perinuclear regions. Staining: Amyloid beta as green fluorescent signal with DAPI (blue) nuclear counterstain.

Immunohistochemical detection of beta Amyloid using Anti-Beta Amyloid Antibody on TG APP23 mouse brain cortex frozen sections. Anti-Beta Amyloid Antibody used at 1:200 and incubated for 2 hours in TBS/BSA with Tween and azide. Fluorescent labelled anti rabbit IgG was then added.

Immunohistochemistry with anti-beta amyloid antibody showing amyloid beta plaque staining in human Alzheimer's disease brain at 10x and 20x (B & C). Staining was performed on Leica Bond system using the standard protocol. Formalin fixed/paraffin embedded tissue sections were subjected to antigen retrieval with E1 (Leica Microsystems) retrieval solution for 20 min and then incubated with rabbit anti-beta amyloid antibody orb345371 at 1:100 dilution for 60 minutes. Biotinylated Anti-rabbit secondary antibody was used at 1:200 dilution to detect primary antibody. The reaction was developed using streptavidin-HRP conjugated compact polymer system and visualized with chromogen substrate, 3'3-diamino-benzidine substrate (DAB). The sections were then counterstained with hematoxylin to detect cell nuclei.
