Mouse cortical neurons in culture. The green staining is APP-immunoreactivity, using fluorescein-labeled goat anti-chicken IgY (Product #F-1005, Aves Labs) and rhodamine-labeled phalloidin as a counterstain. Note the APP-staining of the neurites and growth cones, and the phalloidin-staining limited to the distal growth cones and filapodia. Photomicrograph courtesy of Dr. Philip Copenhaver (OHSU).
Chickens were immunized with a keyhole limpet hemocyanin (KLH) conjugate of the synthetic peptide QHF QEK VES LEQ EAA NER QQ, which corresponds to residues #433-452 of the human gene product (NP_000475.1). This sequence is also conserved in the mouse and rat APP gene products, as well. After repeated injections, immune eggs were collected from the hens, and the IgY fractions were purified from the yolks. These IgY fractions were then affinity-purified against the cognate peptide using an agarose column, the concentration of the eluates adjusted to 100 µg/mL, and the preparation was filter-sterilized.

Validation and Application Notes
IHC Dilution Range: 1:1000-1:2000
This anti-peptide antibody mixture was analyzed by immunohistochemistry (at a dilution of 1:1000) using fluorescein-labeled goat anti-chicken IgY (1:500 dilution, Aves Labs Cat.# F-1005) as the secondary reagent.
Store at 4°C in the dark. Under these conditions, the antibodies should have a shelf life of at least 12 months (provided they remain sterile). Do not freeze these antibodies unless you want to store them for longer periods of time. Note, however, that each time an antibody preparation is frozen, about half of its binding activity is lost.
