Recombinant Human CD154 is an E.coliderived protein corresponding to human CD154, also known as CD40 ligand, CD40L or TRAP. CD154 is a membrane protein expressed by activated T cells. Binding of CD154 to its ligand (CD40) on B cells induces B cell proliferation and immunoglobulin class switching.
This preparation of Recombinant Human CD154 comprises the receptor binding TNF-like domain of human CD154.
Purified recombinant protein - lyophilised
Reconstitute with 10ul 5-10mM sodium phosphate pH7.5. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
