Description:
Interleukin-6 Human Recombinant produced in CHO is a single, glycosylated polypeptide chain containing 185 amino acids and migrates at 22 kDa as a glycosilated protein on SDS-PAGE.
The IL6 is purified by proprietary chromatographic techniques.
Source:
Chinese Hamster Ovarian Cells.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:
Lyophilized without additives.
Solubility:
It is recommended to reconstitute the lyophilized Interleukin-6 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability:
Lyophilized Interleukin-6 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL6 should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Purity:
Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Amino acid sequence:
The activity was measured in a cell prolifiration assay using B9 cells. The ED50 for this effect is 0.7-2 pg/ml.
Biological Activity:
The ED50 as determined by the dose-dependant stimulation of TF-1 cells is < 0.2 ng/ml, corresponding to a Specific Activity of 5x106 IU/mg.
Usage:
ProteinTools products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
