CD40 ligand, also known as CD40LG, is a member of the TNF superfamily and is expressed on activated T cells. CD40LG is expressed as a soluble cytokine as well as a homotrimeric type II transmembrane protein. It has been reported to be important for B cell costimulation following binding of its receptor, CD40. Mutations in the gene encoding for CD154 are implicated in hyper-IgM immunodeficiency syndrome type 1.\n\nSource: \nRecombinant corresponding to aa113-261 from human CD40LG, fused to His-tag at N-terminus expressed in E.coli.\n\nAA Sequence:\nMGSSHHHHHH SSGLVPRGSH MQKGDQNPQI AAHVISEASS KTTSVLQWAE KGYYTMSNNL VTLENGKQLT VKRQGLYYIY AQVTFCSNRE ASSQAPFIAS LCLKSPGRFE RILLRAANTH SSAKPCGQQS IHLGGVFELQ PGASVFVNVT DPSQVSHGTG FTSFGLLKL\n\nMolecular Weight: \n~18.3kD (169aa), confirmed by MALDI-TOF\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
