BP004132: Human IL-33 Protein with No Tag
Source: The recombinant Human IL-33 Protein, (amino acids Ser112-Thr270) fused with No Tag, was produced in E.coli cells.
Molecular Weight:The recombinant Human IL-33 Protein has a predicted MW of 18 kDa same as Tris-Bis PAGE result.
Activity: Immobilized recombinant Human IL-33, No tag at 5 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Human IL-1RL1, His tag with the EC50 of 9.6 ng/ml determined by ELISA.
Purity: >95% by SEC-HPLC and SDS-PAGE under reducing conditions.
Endotoxin Level: Less than 1 EU per ug of protein as determined by LAL method.
Formulation: Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution: It is recommended to reconstitute the lyophilized recombinant Human IL-33 Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening.
Shipping: The recombinant Human IL-33 Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 week, 2 to 8°C under sterile conditions after reconstitution.
6 months, -20 to -70°C under sterile conditions after reconstitution.
