HEK 293




P24394 (M1-R232)

Gene ID


Interleukin-4 receptor subunit alpha; IL4R alpha; IL4R; CD124
AA Sequence

Molecular Weight

Approximately 25.2 kDa.


Greater than 95% as determined by reducing SDS-PAGE.

Biological Activity
Measured by its binding ability in a functional ELISA. Immobilized IL-4 at 10 μg/mL (100 μL/well) can bind cynomolgus IL-4R and the EC50 is 50-120 ng/mL.

Lyophilized powder.


Lyophilized a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.


It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

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

  • 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)
× = ×
C1   V1   C2   V2

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
