Description

Aminopeptidase N/APN Protein, Human (HEK 293, His) is a recombinant aminopeptidase N/APN protein with a His tag. APN (also known as CD13) is a Zn2+ dependent membrane-bound ectopeptidase that degrades preferentially proteins and peptides with a N-terminal neutral amino acid[1].

Background

Aminopeptidase N (APN, CD13) is a zinc-dependent ectopeptidase of the M1 family. It is a type II integral membrane protein and is located on the surface of many mammalian cells like fibroblasts, epithelial and myeloid cells. APN consists of 967 amino acids (aa), which can be divided into three regions. A short N-terminal region is located in the cytoplasm (aa 1–9), followed by a single-helix transmembrane domain (aa 10–27) and a large extracellular region (aa 28–967). APN is involved in multiple processes. It is most widely known for its protease activity in the renin-angiotensin system, where it proteolytically converts angiotensin III to IV. In addition to its enzymatic activity, it functions as a receptor for coronaviruses and has been proposed to participate in the endocytosis of cholesterol. Some of the functions of APN are mediated by protein-protein interactions[2].

Biological Activity

Measured by its ability to cleave the fluorogenic peptide substrate, Ala-7-amido-4-methylcoumarin (Ala-AMC). The specific activity is 9172.6  pmol/min/µg, as measured under the described conditions.

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 activity calculator equation

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

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