CD40L is a high activity construct in which two trimeric CD40 ligands are artificially linked via the collagen domain of ACRP30. This construct very effectively simulates the natural membrane-assisted aggregation of CD40L in vivo. It provides a simple and equally potent alternative to combinations. CD40L has shown to suppress alum-induced IL-1beta release and caspase-1 activation in a dose-, CD40- and time dependent manner, without affecting BMDM viability. It also effectively suppressed the inflammasome function triggered by NLRP3 activators. The secretion of caspase-1 independent inflammatory mediators has been shown to be unaltered or even enhanced.
Biological Activity:
Induces B cells activation (as demonstrated by dose-dependent upregulation of CD86) (ED50: <1ng/ml).
Sequence:
Rat CD40L (aa 115-260) is fused at the N-terminus to mouse ACRP30headless (aa 18-111) and a FLAG(R)-tag.
Storage and Stability:
Short-term Storage: +4 degrees C
Long-term Storage: -20 degrees C
Stable for at least 6 months after receipt when stored at -20 degrees C.
