Background of Cathepsin D
Cathepsin D is a protein that in humans is encoded by the CTSD gene. This proteinase is a member of the peptidase C1 family, having a specificity similar to but narrower than that of pepsin A. It is mapped to 11p15.5. The cDNA encodes a 412-amino acid protein with 20 and 44 amino acids in a pre- and prosegment, respectively. Cathepsin D is one of the lysosomal proteinases. It is ubiquitously expressed and is involved in proteolytic degradation, cell invasion, and apoptosis. Mutations in this gene are involved in the pathogenesis of several diseases, including breast cancer and possibly Alzheimer disease and it has been considered as a breast cancer tumor marker.
Antibody Validation
Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Figure 1. IHC analysis of Cathepsin D using anti-Cathepsin D antibody (PB9047).
Cathepsin D was detected in a paraffin-embedded section of human lung cancer tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 1 μg/ml rabbit anti-Cathepsin D Antibody (PB9047) overnight at 4°C. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using Strepavidin-Biotin-Complex (SABC) (Catalog # SA1022) with DAB as the chromogen.

Figure 2. Western blot analysis of Cathepsin D using anti-Cathepsin D antibody (PB9047).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours.
Lane 1: recombinant human Cathepsin D protein 0.5 ng.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-Cathepsin D antigen affinity purified polyclonal antibody (Catalog # PB9047) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for Cathepsin D at approximately 40 kDa. The expected band size for Cathepsin D is at 40 kDa.

Asked: 2019-12-13
Answer
The anti-Cathepsin D/CTSD antibody (PB9047) has not been tested for cross reactivity specifically with canine tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in canine you can get your next antibody for free. Please contact me if I can help you with anything.
