Interleukin-9 Human Recombinant, HEK ( IL 9 Human, HEK )

Data sheet

Formulation

The IL9 was lyophilized from 1mg/ml in 1xPBS.

Solubility

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

Purity

Greater than 95% as obsereved by SDS-PAGE.

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.

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

HEK.

Synonyms

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

Stability

Lyophilized IL-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 add a car

Physical Appearence

Sterile Filtered White lyophilized (freeze-dried) powder.

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.
