Request for sequence

蛋白结构（Molecular Characterization）

This protein carries no "tag".

The protein has a calculated MW of 15.4 kDa. The protein migrates as 15 kDa under reducing (R) condition.

内毒素（Endotoxin）

Less than 0.1 EU per μg by the LAL method.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 20 mM PB, pH3.5. Normally trehalose is added as protectant before lyophilization.

Contact us for customized product form or formulation.

重构方法（Reconstitution）

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

存储（Storage）

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.

电泳（SDS-PAGE）

Human IL-2, Tag Free on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

活性（Bioactivity）-ELISA

Immobilized Human IL-2 R alpha, Fc Tag at 2μg/mL (100 μL/well) can bind Human IL-2, Tag Freewith a linear range of 0.2-1.56 ng/mL (QC tested).

Protocol

Report

活性（Bioactivity）-SPR

Protocol

活性（Bioactivity）-BLI

Loaded Human IL-2 R beta, His Tag (SPR verified) (on HIS1K Biosensor, can bind Human IL-2, Tag Free with an affinity constant of 0.46 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

Protocol

Loaded Human IL-2 R alpha, His Tag on HIS1K Biosensor, can bind Human IL-2, Tag Free with an affinity constant of 18 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

Protocol

活性（Bioactivity）-Cell based assay
