Cathepsin B Protein, Human (His)

Cat. No.: HY-P70830
COA Handling Instructions

Cathepsin B Protein, a thiol protease, is crucial for intracellular protein degradation, cleaving matrix extracellular phosphoglycoprotein MEPE. It's implicated in solubilizing cross-linked TG/thyroglobulin in the thyroid follicle lumen. Associated with tumor invasion and metastasis, Cathepsin B signifies potential relevance in cancer-related pathways. Cathepsin B Protein, Human (His) is the recombinant human-derived Cathepsin B protein, expressed by E. coli , with C-6*His labeled tag. The total length of Cathepsin B Protein, Human (His) is 322 a.a., with molecular weight of 34 & 38-50 kDa, respectively.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity 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 activity calculator equation

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

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