Source

Human IL-9 Protein, His Tag (IL9-H52H9) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Ile 144 (Accession # P15248-1).

Predicted N-terminus: Gln 19

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 16.0 kDa. The protein migrates as 28-37 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 0.1 EU per μg by the LAL method / rFC method.

Sterility

Negative

Mycoplasma

Negative

Purity

>90% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background

Interleukin-9 (IL-9) is expressed primarily by activated T cells. The growth factor and anti apoptotic activities of IL-9 on multiple transformed cells suggest a potential role for the cytokine in tumourigenesis. IL-9 has also been proposed as a candidate gene for asthma. IL-9 is a Th2-derived cytokine that has been reported to regulate T and B cell function. IL-9 was first isolated as a factor capable of sustaining the long-term growth of murine T cell clones, but has since been demonstrated to have in vitro activities on mast cells, erythroid progenitors, and B cell Ig expression.
