Description

Cathepsin D Protein, Mouse (HEK293, His) is an approximately 56.0 kDa mouse cathepsin D with a His tag. Cathepsin D is a lysosomal aspartic protease of the pepsin family[1].

Background

Cathepsin D, a lysosomal aspartic protease, belongs to the pepsin family. Mouse Cathepsin D consists of a signal peptide (residues 120), a propeptide (residues 2164), and a mature chain (residues 65410) (13). Cathepsin D is expressed in most cells and overexpressed in in some cancer (breast, melanoma, ovary, etc.). Cathepsin D increases the incidence of clinical metastasis involves increased cell growth and decreased contact inhibition rather than escape of cancer cells through the basement membrane[1][2].
Cathepsin D acts as a protease following its activation at an acidic pH, or as a ligand of different membrane receptors at a more neutral pH[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
