Human IL-5 Protein, His Tag
IL-5,TRF,IL5,Interleukin-5
Human IL-5, His Tag is expressed from human 293 cells. It contains AA Ile 20 - Ser 134 .
Predicted N-terminus: His
Request for sequence
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 15.0 kDa. The protein migrates as 18-23 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to -70°C for 12 months in lyophilized state;
-70°C for 3 months under sterile conditions after reconstitution.
Human IL-5, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
Immobilized Human IL-5, His Tag at 5 μg/mL (100 μL/well) can bind Human IL-5 R alpha, Fc Tag with a linear range of 0.02-0.313 μg/mL (QC tested).
Protocol
Loaded Human IL-5, His Tagon NTA Biosensor, can bind Human IL-5 R alpha, Fc Tag with an affinity constant of 4.63 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
