Background of Cathepsin E
Cathepsin E is an enzyme that in humans is encoded by the CTSE gene. This gene encodes a member of the A1 family of peptidases. Alternative splicing of this gene results in multiple transcript variants. At least one of these variants encodes a preproprotein that is proteolytically processed to generate the mature enzyme. This enzyme, an aspartic endopeptidase, may be involved in antigen processing and the maturation of secretory proteins. Elevated expression of this gene has been observed in neurodegeneration.
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. Western blot analysis of Cathepsin E using anti-Cathepsin E antibody (A04874-1).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 50ug of sample under reducing conditions.
Lane 1: rat stomach tissue lysates,
Lane 2: mouse stomach tissue lysates,
Lane 3: mouse SP20 whole cell lysates.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA 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 E antigen affinity purified polyclonal antibody (Catalog # A04874-1) at 0.5 μg/mL overnight at 4℃, 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 1:10000 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 E at approximately 48KD. The expected band size for Cathepsin E is at 43KD.

Figure 2. IHC analysis of Cathepsin E using anti-Cathepsin E antibody (A04874-1).
Cathepsin E was detected in paraffin-embedded section of human Lung cancer tissue. Heat mediated antigen retrieval was performed in citrate buffer (pH6, epitope retrieval solution) for 20 mins. The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2μg/ml rabbit anti-Cathepsin E Antibody (A04874-1) overnight at 4℃. Biotinylated goat anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37℃. The tissue section was developed using Strepavidin-Biotin-Complex (SABC)(Catalog # SA1022) with DAB as the chromogen.

Question
We are currently using anti-Cathepsin E/CTSE antibody A04874-1 for mouse tissue, and we are happy with the IHC results. The species of reactivity given in the datasheet says human, mouse, rat. Is it true that the antibody can work on monkey tissues as well?

Answer
The anti-Cathepsin E/CTSE antibody (A04874-1) has not been tested for cross reactivity specifically with monkey 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 monkey you can get your next antibody for free. Please contact me if I can help you with anything.
