• Source:

  Mammalian cell

• Field of Research:

  Cancer

• Relevance:

  Cytokine produced by activated CD4-positive helper T-cells and to a lesser extend activated CD8-positive T-cells and natural killer (NK) cells that plays pivotal roles in the immune response and tolerance.Binds to a receptor complex composed of either the high-affinity trimeric IL-2R (IL2RA/CD25, IL2RB/CD122 and IL2RG/CD132) or the low-affinity dimeric IL-2R.

• Endotoxin:

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

• Purity:

  Greater than 95% as determined by SDS-PAGE.

• Activity:

  Yes

• Bioactivity:

  Measured by its binding ability in a functional ELISA. Immobilized Human IL2RA (CSB-MP011649HU3) at 2 μg/mL can bind Human IL2 , the EC50 is 0.4992 to 0.6269 ng/mL.

• Form:

  Lyophilized powder

• Buffer:

  Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, 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.

• 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.
