b'Novex AP Chemiluminescent Substrate (CDP-Star)CSPD SubstrateInvitrogen Novex AP Chemiluminescent Substrate is a nonradioactive ready-to-use CDP-Star solution for chemiluminescence-based immunodetection of AP on western blot or dot blot membranes. This reagent provides detection sensitivities superior to that of precipitating chromogenic substrates. Low-picogram levels of detection can be achieved using either X-ray film or imaging equipment.Features:Good signal-to-noise ratiohigh specificity, clean background Invitrogen CSPD Substrate is a chemiluminescent AP substrate, ready to use for protein or nucleic acid blottingHigh sensitivitylow-picogram to femtogram levelson PVDF and nitrocellulose membranes (with Nitro-Block detectable enhancer). The CSPD chemiluminescent substrate lets youLong signal durationup to 5 days detect AP and AP-labeled molecules with a high level of sensitivity, speed, and ease.Fastresults in less than 3 hoursThis versatile chemiluminescent substrate exhibits high sensitivity in membrane-based applications such as Southern, northern, and western blotting. Maximum light levels are reached in approximately 10 minutes, and glow emission persists for several hours.Features: Chemiluminescent substrates provide highly sensitivereplacements for the widely used fluorogenic substrate methylumbelliferyl phosphate (MUP), and the colorimetric substrate p-nitrophenyl phosphate (pNPP) Low background luminescence coupled withhigh-intensity light output enables detection of AP labels Did you know with exceptional sensitivity and signal-to-noise ratioColorimetric or chromogenic substrates cannot be stripped using stripping buffers because a colored precipitate is formed during the detection process.53'
