Product Overview

Clone CTD-19 is a mouse monoclonal antibody that recognizes cathepsin D (gene Ctsd) in human samples and is validated for Western blot and IHC.

Cathepsin D (CTSD) is a lysosomal aspartic protease that carries out bulk breakdown of proteins in acidic compartments. It also participates in processing of proteins such as amyloid precursor protein. CTSD is studied in lysosomal function, neurodegeneration and breast cancer, where its secretion has been widely investigated.

Formulation 1.2% sodium acetate; 0.01 mg NaN3; plus stabilizers
Reconstitution 100 µg/mL after adding 1 mL PBS
Storage As supplied: −20 °C for up to 12 months from receipt. After reconstitution: 4 °C for up to 1 month, or aliquot and keep at −20 °C for up to 6 months. Avoid repeated freeze–thaw cycles.

Validated Applications

IHC (paraffin sections) 1–2 µg/mL (Human)
Western blot 0.5–1 µg/mL (Human)

Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).

Immunogen

Human liver cathepsin D.

Reactivity Notes

The supplier lists reactivity with human. UniProt describes cathepsin D as secreted and also located in the lysosome and melanosome.

Safety

Handling: the formulation contains sodium azide as a preservative. Wear gloves, avoid contact with skin and eyes, and dispose of waste according to local regulations. For research use only; not for diagnostic or therapeutic procedures.
Q.Which applications is this antibody validated for, and at what dilution?
A.Validated applications with suggested starting dilutions: Western blot 0.5–1 µg/mL (Human); IHC (paraffin sections) 1–2 µg/mL (Human). Optimal dilutions should be determined by each laboratory.
Q.Which species does this antibody react with?
A.Validated reactivity: Human. Other species are not listed by the supplier.
Q.Has this antibody been tested on porcine samples?
A.Reactivity with porcine samples has not been tested by the supplier. Aligning the immunogen sequence with the porcine ortholog (e.g., by BLAST) helps estimate the chance of cross-reactivity.
Q.What immunogen was used to raise this antibody?
A.Human liver cathepsin D.
Q.How should this antibody be stored?
A.As supplied: −20 °C for up to 12 months from receipt. After reconstitution: 4 °C for up to 1 month, or aliquot and keep at −20 °C for up to 6 months. Avoid repeated freeze–thaw cycles.
