Active Recombinant Pig IL1B Protein (Ala115-Pro267), C-His tagged, Animal-free, Carrier-free

• Cat.No.: IL1B-205P
• Product Overview: Recombinant Pig IL1B Protein (Ala115-Pro267) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: 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 resistance. Pro-IL-1β is cleaved by cytosolic caspase 1 to form mature IL-1β.
• Source: E. coli
• Species: Pig
• Tag: C-His
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce D10.G4.1 cells proliferation. The ED50 for this effect is < 3 ng/mL.
• Molecular Mass: The protein has a calculated MW of 18.51 kDa. The protein migrates as 20 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Ala115-Pro267
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 1 month under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
• Shipping: The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.
