Interleukin-9 Human Recombinant ( IL 9 Human )

Data sheet

Formulation

IL-9 protein was lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized Interleukin-9 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

Interleukin-9 Human Recombinant produced in E.Coli is a single, non-glycosylated single polypeptide chain containing 127 amino acids and having a molecular mass of 14,004 Dalton. The IL-9 is purified by proprietary chromatographic techniques.

Protein Background

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

Expression host

Escherichia Coli.

Synonyms

P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Interleukin-9 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL9 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
