Other Performance Data: Biological Activity: IL-9 is fully biologically active when compared to a standard. The ED50 as determined by the dose-dependent proliferation of human MO7e cells is < 0.5 ng/ml.Endotoxin Level: Measured by LAL is <0.01ng/µg or <0.1EU/µg.
Physical State: Lyophilized
Purity and Specificity: Purity was determined to be greater than 98% as determined by analysis by RP-HPLC and by reducing and non-reducing SDS- PAGE, against known standard.
Background: Interleukin (IL-9) is known to regulate many cell types involved in T- helper type 2 responses classically associated with asthma, including B- and T- lymphocytes, mast cells, eosinophils and epithelial cells. Growing evidence obtained from human genomic analysis and antigen-challenged transgenic mice suggests that IL-9 is a candidate factor in immunoglobulin E (IgE) production and thus is thought to be associated with bronchial inflammation and bronchial hyperresponsiveness (BHR). Recombinant Human IL-9 produced in E.coli is a single, non-glycosylated single polypeptide chain containing 127 amino acids and having a molecular mass of 14,004 Daltons.
