• Tag:

  Tag-Free

• Type:

  Active Protein & In Stock Protein

• Source:

  E.Coli

• Field of Research:

  Immunology

• Relevance:

  Cytokine that stimulates the proliferation of T-lymphocytes. Stimulation by IL-15 requires interaction of IL-15 with components of IL-2R, including IL-2R beta and probably IL-2R gamma but not IL-2R alpha.

• Endotoxin:

  Less than 1.0 EU/μg as determined by LAL method.

• Purity:

  >97% as determined by SDS-PAGE.

• Activity:

  Yes

• Bioactivity:

  Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine CTLL-2 cells is less than 0.5 ng/ml, corresponding to a specific activity of > 2.0 x 106 IU/mg.

• Form:

  Lyophilized powder

• Buffer:

  Lyophilized from a 0.2 µm filtered PBS, pH 7.4

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Function:

  Cytokine that stimulates the proliferation of T-lymphocytes. Stimulation by IL-15 requires interaction of IL-15 with components of IL-2R, including IL-2R beta and probably IL-2R gamma but not IL-2R alpha.

• Molecular Weight:

  12.9 kDa

• Storage Conditions:

  The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

• Protein Length:

  Full Length of Mature Protein
