Description

Cathepsin D Protein, Human (HEK293, His) is an approximately 50.0 kDa cathepsin D protein with a His-flag. Cathepsin D is a representative lysosomal aspartic proteinases and belongs to the peptidase C1 family[1].

Background

Cathepsin D (CTSD), a well-known lysosomal aspartyl protease and belongs to the peptidase C1 family, which is a normal and major component of lysosomes, and is found in almost all cells and tissues of mammals[1].
Human cathepsin D is synthesized as a precursor protein, consisting of a signal peptide (residues 1-18), a propeptide (residues 1964), and a mature chain (residues (65412))[2].

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.

  • Dilution Calculator

  • Specific Active Calculator

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
