Recombinant Cynomolgus IL-10 R alpha Protein is expressed from HEK293 with His tag at the C-terminal.It contains His22-Asn233.
IL-10 R alpha
The protein has a predicted MW of 25.34 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on Tris-Bis PAGE result.
Immobilized Human IL-10, No Tag at 1ug/ml (100ul/well) on the plate. Dose response curve for Cynomolgus IL-10 R alpha, His Tag with the EC50 of 8.9ng/ml determined by ELISA (QC Test). The affinity constant of 0.93 nM as determined in SPR assay (Biacore T200). See testing image for detail.

Less than 1EU per ug by the LAL method.
Shipped at ambient temperature.
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
