Description

dapb2 Protein, Pseudoxanthomonas mexicana (Flag, His) is the recombinant dapb2, expressed by E. coli , with His, Flag labeled tag.
Background

dapb2 is an exopeptidase that catalyzes the removal of dipeptide units (NH2-P2-P1-) from the free amino termini of oligopeptides and small proteins. Peptide digestion occurs sequentially with nonspecific substrate recognition, except that Pro is unsuitable as a P1 residue. It removes residues from bioactive oligopeptides like angiotensin I and neuromedin N, cleaves oxidized insulin B chain, and hydrolyzes X-Pro bonds (an imido bond) without endopeptidase activity. May play a physiological role in feeding. by similar: Additional studies suggest its substrate recognition may involve broader peptide structural features.

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
