AA Sequence


Molecular Weight

Approximately 16.2 kDa


Greater than 95% as determined by SDS-PAGE.

Biological Activity
The ED50 as determined by the dose-dependent stimulation of IL-12 & IL-8 induction by PMB cells is less than 20 μg/mL.

Lyophilized powder.


Lyophilized from a 0.2 μm solution of 20 mM PBS, 200 mM NaCl, 0.1 mM EDTA, pH 7.0.

Endotoxin Level

<1 EU/μg, determined by LAL method.


It is not recommended to reconstitute to a concentration less than 100 μg/mL in sterile distilled water.

Storage & Stability

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.


Room temperature in continental US;may vary elsewhere.

  • Reconstitution Calculator

  • Dilution 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)
× = ×
