Recombinant Human CD4 protein, His-Avi-tagged

• Cat.No.: CD4-293H
• Product Overview: Human CD40 is expressed from mammalian with a His and a Avi tag at the C-terminal. It contains Glu21-Arg193.

Specification

• Description: CD40 is a costimulatory protein found on antigen presenting cells and is required for their activation. The binding of CD154 (CD40L) on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects.CD40 molecule is a potential target for cancer immunotherapy. There are number of completed and ongoing clinical trials where agonistic anti-CD40 monoclonal antibodies are employed to activate an anti-tumor T cell response via activation of dendritic cells.
• Source: HEK293
• Species: Human
• Tag: His-Avi
• Form: Supplied as 0.22um filtered solution in PBS (pH 7.4).
• Molecular Mass: The protein has a predicted MW of 22.1 kDa. Due to glycosylation, the protein migrates to 35-40 KDa based on Bis-Tris PAGE result.
• Protein length: It contains Glu21-Arg193.
• Endotoxin: Less than 0.1 EU per ug by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: The product should be stored at -70°C. Please do not repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
