Active Recombinant Human IL5 Protein

• Cat.No.: IL5-182H
• Product Overview: Recombinant Human IL5 Protein without tag was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Description: Interleukin 5 (IL-5) is a hematopoietic growth factor that is expressed in type 2 T helper (Th2) cells, mast cells, and eosinophils. IL-5 acts through the IL-5 receptor (IL-5R), stimulates B cell growth, and mediates eosinophil activation. Human and mouse IL-5 show cross-reactivity.
• Bio-activity: TF-1 cell proliferation, ≤250 pg/mL; ≥4.0 x 10^6 units/mg
• Molecular Mass: Dimer, 13.3/26.6 kDa (116/232 aa)
• AA Sequence: MIPTEIPTSALVKETLALLSTHRTLLIANETLRIPVPVHKNHQLCTEEIFQGIGTLESQTVQGGTVERLFKNLSLIKKYIDGQKKKCGEERRRVNQFLDYLQEFLGVMNTEWIIES
• Endotoxin: ≤1 EUs/μg, Kinetic LAL
• Purity: ≥95%, Reducing and Non-Reducing SDS PAGE
• Stability: 12 months from date of receipt when stored at -20 to -80 centigrade as supplied.
  1 month when stored at 4 centigrade after reconstituting as directed.
  3 months when stored at -20 to -80 centigrade after reconstituting as directed.
• Storage: Storage Prior to Reconstitution: -20 centigrade
• Storage Buffer: Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 10 mM sodium glycinate, pH 8.5
• Reconstitution: Sterile water at 0.1 mg/mL
• Shipping: Room temperature
• Instructions: Centrifuge vial before opening. Suspend the product by gently pipetting the above recommended solution down the sides of the vial. DO NOT VORTEX. Allow several minutes for complete reconstitution. For prolonged storage, dilute to working aliquots in a 0.1% BSA solution, store at -80 centigrade and avoid repeat freeze thaws.
