Synonyms :

Lymphopoietin 1(LP-1), pre-B cell factor

Description :

IL-7 is a hematopoietic growth factor which affects primarily early B and T cells. Produced by thymic stromal cells, spleen cells and keratinocytes, IL-7 can also co-stimulate the proliferation of mature T cells in combination with other factors such as ConA and IL-2. Human and murine IL-7 is cross-species reactive. Recombinant human IL-7 is a 17.4 kDa protein containing 153 amino acid residues.

Source :

E.coli

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted IL-7 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per µg (1EU/µg).

Biological Activity :

The ED₅₀ was determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells is ≤ 0.5 ng/ml, corresponding to a specific activity of ≥ 2 x 10⁶ units/mg.
