Active Recombinant Human CD40LG Protein (Met1-Leu261), C-His tagged, Animal-free, Carrier-free

• Cat.No.: CD40LG-323H
• Product Overview: Recombinant Human CD40LG Protein (Met1-Leu261) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Human CD40L (CD154) is one member of TNF family which is expressed on T cells. It binds the CD40, which is on the antigen-presenting cells (ex: B cells, macrophages and monocytes) Human CD40L is a 21.6 kDa cytokine with 103 amino acid residues which is a transmembrane glycoprotein. Human CD40L plays an important role in the adaptive immune system which induces the B cell maturation and activation.
• Source: E. coli
• Species: Human
• Tag: C-His
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce IL-8 secretion in human PBMCs. The ED50 for this effect is < 5 ng/mL.
• Molecular Mass: The protein has a calculated MW of 16.99 kDa.
  The protein migrates as 16 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Met1-Leu261
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >95% 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 8.0.
• 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.
