< 0.1 EU per 1 ug of the protein by the LAL method.
Activity:
Measure by its ability to induce TF-1 cells proliferation. The ED50 for this effect is < 80 pg/mL. The specific activity of recombinant human CSF2 is approximately > 1 x 107 IU/ mg.
Quality Control Testing:
SDS-PAGE Stained with Coomassie Blue
Recommend Usage:
SDS-PAGE The optimal working dilution should be determined by the end user.
Storage Buffer:
Lyophilized from a solution containing 1X PBS, pH 8.0. It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 ug/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.Please use within one month after protein reconstitution.
Storage Instruction:
Store at -20°C, lyophilized protein is stable for 1 year. After reconstitution with deionized water, store at -20 to -80°C. Aliquot to avoid repeated freezing and thawing.
Applications
Functional Study
Measure by its ability to induce TF-1 cells proliferation. The ED50 for this effect is <80 pg/mL..
The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13. [provided by RefSeq
