Name: Recombinant IL-1 beta, Human, GMP
Price: 1453.00 USD

- Overview
  - Interleukin-1 beta (IL-1β) is a major cytokine expressed in macrophage, NK cells, monocytes, and neutrophils. It also plays fundamental role in inflammatory response, including monocyte activation, which is essential for the host defense and pathogen and pathogen resistance. Pro-IL-1β is cleaved by cytosolic caspase 1 to form mature IL-1β.

    Reactivity
    
    Human
    
    Purification
    
    >98% as determined by SDS-PAGE analysis.
    
    Formulation
    
    Lyophilized from a 0.2µm filtered solution of PBS, pH 8.0.
    
    Storage
    
    Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
    
    Note
    
    Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 0.5 mg/mL and incubate the stock solution at RT for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
    
    Molecular Weight
    
    The protein has a calculated MW of 18.5kDa. The protein migrates as 17kDa under reducing condition (SDS-PAGE analysis).

    Activity
    
    Measure by its ability to induce IL-8 secretion in HT29 cells. The ED50 for this effect is <2.0ng/mL. The specific activity of recombinant human IL-1 beta is approximately >3x10^7 IU/mg, which is calibrated against the human IL-1 beta WHO International Standard (NIBSC code: 86/680).
