IL-13R alpha 2 Protein, Canine (HEK293, His)

IL-13R alpha 2 Protein, functioning as a monomer, exhibits a strong binding affinity for interleukin-13 (IL-13). IL-13R alpha 2 Protein, Canine (HEK293, His) is the recombinant canine-derived IL-13R alpha 2 protein, expressed by HEK293, with C-His labeled tag. The total length of IL-13R alpha 2 Protein, Canine (HEK293, His) is 317 a.a., with molecular weight of 39-46 kDa.

IL-13R alpha 2 Protein

Measured by its ability to inhibit IL13-dependent proliferation of TF-1 human erythroleukemic cells. The ED₅₀ for this effect is typically 0.01287 μg/mL, corresponding to a specific activity is 7.770×10⁴ U/mg.

Greater than 95% as determined by reducing SDS-PAGE

Lyophilized powder

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

<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).

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.
