ST2/IL1RL1 Protein, Human (HEK293, Fc)

ST2/IL1RL1 Protein potently inhibits IL-33 signaling. ST2/IL1RL1 Protein, Human (HEK293, Fc) is the recombinant human-derived ST2/IL1RL1 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of ST2/IL1RL1 Protein, Human (HEK293, Fc) is 310 a.a., with molecular weight of 75-100 kDa.

ST2/IL1RL1 protein serves as a potent inhibitor of IL-33 signaling.

Immobilized Human IL-33, No Tag at 2 μg/mL (100 μl/well) on the plate. Dose response curve for Human IL-1RL1, hFc Tag with the EC₅₀ of ≤9.9 ng/mL determined by ELISA.

75-100 kDa

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

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
