产品英文概述

来源

Escherichia coli.

分子量

Approximately 15.0 kDa, a single non-glycosylated polypeptide chain containing 129 amino acids.

生物活性

Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 0.2 ng/ml, corresponding to a specific activity of > 5.0 × 106 IU/mg.

外观

Sterile filtered white lyophilized (freeze-dried) powder.

配方

Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4.

内毒素

Less than 0.01 EU/ug of rHuIL-4 GMP as determined by LAL method.

溶解说明

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

储存条件

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- A minimum of 12 months when stored at ≤ -20 °C as supplied. Refer to lot specific COA for the Use by Date.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
