CSPD™ Substrate (25 mM Concentrate) (Invitrogen™)

This concentrated CSPD™ substrate is a chemiluminescent alkaline phosphatase substrate for protein or nucleic acid blotting on nitrocellulose membranes. This substrate can also be used in solution-based assays.

This CSPD™ chemiluminescent substrate for alkaline phosphatase let you detect alkaline phosphatase and alkaline phosphatase-labeled molecules with unparalleled sensitivity, speed, and ease.

• Chemiluminescent substrates provide highly sensitive replacements for the widely used fluorogenic substrate methylumbelliferyl phosphate (MUP), and the colorimetric substrate p-nitrophenyl phosphate (pNPP).
• Low background luminescence coupled with high-intensity light output enables detection of alkaline phosphatase labels with the highest possible sensitivity and signal-to-noise.

This versatile chemiluminescent substrate exhibits high sensitivity in membrane-based applications such as Southern, Northern, and Western blotting. This substrate can also be used in solution-based assays such as immunoassays, DNA probe assays, enzyme assays, and reporter gene assays. Maximum light levels are reached in approximately 10 minutes and glow emission persists for several hours. Solution assays require chemiluminescent enhancers. Membrane-based assays may also require them for increased light output and sensitivity.
