Catalog#/Size:AC52385/100 µg.

Source:Escherichia coli.

Molecular Weight:Approximately 12.9 k Da, a single non-glycosylated polypeptide chain containing 115 amino acids. 

Descriptio:Accession # P40933.1, Asn49-Ser162, with an N terminal Met.

SDS-PAGE:9 k Da, reducing conditions.

Purity:>95  %,  as  determined  by  SDS-PAGE,  under  reducing  non-reducing  conditions,visualized  by  coomassie staining.

Endotoxin:Less than 0.01 EU/ µg of rHuIL- 15 as determined by kinetic Limulus Amoebocyte Lysate (LAL) assay.

Biological Activity:Recombinant human IL-15 bioactivity is measured in a cell proliferation assay using Mo7e cells, the EC50 for this effect is 3.500 to 4.556 ng/mL.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:Lyophilized from a 0.2  µm filtered concentrated solution in 20 mM  PBS, pH 7.5 without carrier protein or preservatives.

Reconstitution:We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute  to  a  concentration  of  0.1-1.0   mg/mL  in  sterile  distilled   H2O.  Stock  solutions  should   be apportioned  into working  aliquots  and  stored  at-20 ℃to -70 ℃ .  Further  dilutions  should  be  made  in appropriate buffered solutions. Do not reconstitute in cell culture media directly.

Shipping:The product is shipped at 2to 8. Upon receipt, store it immediately at the temperature recommended below.

Stability & Storage:Use a manual defrost freezer and avoid repeated freeze-thaw cycles.

               A minimum of 12 months from date of shipping when stored at -20 ℃to -70 ℃as supplied. 
               4 weeks at 2  ℃  to 8  ℃  under sterile conditions after reconstitution.

               4 months at -20  ℃ to -70  ℃  under sterile conditions after reconstitution.

Usage:Acnovia rHuIL-15 product can be used for a variety of ex vivo cell culture applications such as research or further manufacturing.

Quality statement:No animal- or human-derived materials were used for the manufacture of this product, unless otherwise stated in the respective Certificate of Origin.



Interleukin 15(IL-15) is a widely expressed pro-inflammatory cytokine that regulates T and natural killer cell activation and proliferation.Together with IL-2, IL-4, IL-7, and IL-9, IL-15 belongs to the four-α -helix protein which is a 14–15 k Da protein that shares many biological activities with IL-2. IL-15 signals through a receptor complex composed of the IL-2/IL-15 receptor  β  (IL-15Rβ) (CD122) subunit and the common gamma chain (γC) (CD132) receptor subunit, and thus negatively regulate each other's activity. The number of CD8+ memory cells is shown to be controlled by a balance between IL-15 and IL-2. IL-15 drives homeostatic (lymphopenic) division of human CD8+ and CD4+ memory T cells, and NK cells. IL-15 has anti-apoptotic effect on CD8+ memory T cells, and on B cells in the germinal centers.

IL-15 is secreted by monocytes, macrophages, Dendritic cells, follicular dendritic cells, stromal cells, T cells, and some cancer cells (prostate, ovary). Dendritic cells can be induced to secrete IL-15 in vitro by engagement of CD40. And the IL-15 essential for NK cell development is produced by bone marrow stromal cells.
