BSPOTPE 

BSPOTPE is the mixture of (E)-BSPOTPE (HY-W856375) and (Z)-BSPOTPE. BSPOTPE binds Human serum albumin (HSA) (HY-P1956), exhibits aggregation-induced emission (AIE) phenomenon. BSPOTPE shows selectivity for albumin (such as HSA and BSA), but has no obvious fluorescence response to other proteins and DNA. BSPOTPE can be used as fluorescent probe for HSA^[1].
