Interleukin-9 Human Recombinant, HEK
Factor that is thought to be a regulator of hematopoiesis. It has been shown to enhance the growth of human mast cells and megakaryoblastic leukemic cells as well as murine helper t-cell clones. IL-9 is a glycoprotein with a molecular weight of 32-39 that is derived from T-cells, and maps to human chromosome 5.
Description | IL-9 Human Recombinant produced in HEK cells is a glycosylated monomer, having a molecular weight range of 38-48kDa due to glycosylation. The IL9 is purified by proprietary chromatographic techniques. |
Synonyms | P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine. |
Source | HEK. |
Purity | >96% as determined by SDS-PAGE and HPLC |
Formulation | Sterile Filtered White lyophilized (freeze-dried) powder. The IL9 was lyophilized from 1mg/ml in 1xPBS. |
Stability | The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles. |
Biological Activity | The specific activity was determined by the dose-dependent stimulation of the proliferation of human MO7e cells (human megakaryoblastic leukemia cell line) and is typically 0.03-0.2ng/ml. |
Solubility | It is recommended to reconstitute the lyophilized IL-9 in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Usage | LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes. |
