CSPD ([3-(1-chloro-3'-methoxyspiro[adamantane-4,4'-dioxetane]-3'-yl)phenyl] dihydrogen phosphate) is a chemical substance with formula C₁₈H₂₂ClO₇P. It is a component of enhanced chemiluminescence enzyme-linked immunosorbent assay (ELISA) kits, used for the detection of minute amounts of various substances such as proteins.^[1]

Properties edit

The molecule CSPD has the following functional groups in the structure: phosphate group, phenyl group, spiro group, methyl ether group, and chlorine group. The ones worth noting are the ones above. None of these groups carry a charge. If there was a charge this would have had a change in the compound's pH, 3D structure, mass and bond angles.^[2]

The toxin CSPD effect persister cell formation using MqsR (MqsR, a crucial regulator for quorum sensing and biofilm formation, is a GCU-specific mRNA interferase in Escherichia coli^[3]) and persister cells are cells that avoid stress and are characterized by reduced metabolism and other factors.^[4]^{[clarification needed]}
