内毒素水平
Less than 0.01 ng per μg protein as determined by the LAL method.
Biological Activity Comment
The ED50 is 1 - 5 ng/ml, corresponding to a specific activity of 0.2 - 1 x 10^6 units/mg, determined by the dose dependent stimulation of mouse BaF3-human IL-7a and human TSLPR cotransfectant cell proliferation.

背景
This gene encodes a hemopoietic cytokine proposed to signal through a heterodimeric receptor complex composed of the thymic stromal lymphopoietin receptor and the IL-7R alpha chain. It mainly impacts myeloid cells and induces the release of T cell-attracting chemokines from monocytes and enhances the maturation of CD11c(+) dendritic cells. The protein promotes T helper type 2 (TH2) cell responses that are associated with immunity in various inflammatory diseases, including asthma, allergic inflammation and chronic obstructive pulmonary disease. The protein is therefore considered a potential therapeutic target for the treatment of such diseases. Alternative splicing of this gene results in multiple transcript variants.
