Product Details


Lymphopoietin 1 (LP-1), pre-B cell factor, IL-7.


Description of Human IL-7

Recombinant human IL-7 is a 17.4 kDa protein containing 152 amino acid residues. 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.


Biological Activity

The ED50 of ≤ 0.5 ng/ml was determined by its ability to stimulate the proliferation of mouse 2E8 cells. It corresponds to a specific activity of ≥ 2.0 x 106 units/mg.



We recommend a quick spin followed by reconstitution in sterile-filtered water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8C for up to 1 week. For long term storage it is recommended to add a carrier protein (0.1% HSA, order number: or, or BSA, order number: and store in working aliquots at -20C to -80C.



The lyophilized protein is stable at room temperature for up to 1 month, at 4C for up to 6 months, and below -20C until expiry date. Reconstituted protein is stable for at least 12 months when stored in working aliquots with a carrier protein at -20C to -80C. Please avoid repeated freeze-thaw cycles.
