Product Information

Product Usage Information

Application Dilution
Immunofluorescence (Frozen) 1:50 - 1:200
Immunofluorescence (Immunocytochemistry) 1:50 - 1:200

Storage

Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

Specificity / Sensitivity

Cathepsin D (E7Z4L) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate) recognizes endogenous levels of preprocathepsin D, procathepsin D, and the heavy and light chain subunit of mature cathepsin D protein.

Species Reactivity:

Mouse

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of mouse cathepsin D protein.

Product Description

This Cell Signaling Technology® antibody is conjugated to Alexa Fluor® 647 fluorescent dye under optimal conditions. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated Cathepsin D (E7Z4L) XP® Rabbit mAb #88239.

Background

Cathepsin D is a ubiquitously expressed lysosomal aspartyl protease involved in the normal degradation of proteins (1). It is synthesized as an inactive 43 kDa preprocathepsin D that is cleaved and glycosylated to form a 46 kDa procathepsin D and then further cleaved to produce 28 kDa and 15 kDa subunits (heavy and light chains, respectively) (2). Cathepsin D may also be secreted into the cytosol during apoptosis and contribute to cleavage of substrates implicated in the apoptotic pathway (3). Numerous studies have suggested that cathepsin D plays a role in neuronal degradation and malignant transformation, particularly in breast cancer (4-9).
