Application

CDP-Star® is a sensitive, chemiluminescent substrate for alkaline phosphatase that allows for the rapid, reproducible detection of alkaline phosphatase-labeled molecules in Northern, Southern, and Western blotting applications. Detection of alkaline phosphatase-labeled molecules with CDP-Star is extremely sensitive as a result of low background luminescence coupled with high intensity and prolonged light output from the enzyme catalysis. Following exposure to alkaline phosphatase-labeled molecules, maximum light emission occurs at approximately 60 minutes and continues for up to 24 hours, allowing for multiple film exposures and/or the sensitive detection of targets present in small amounts. For convenience, CDP-Star is supplied as a 0.25 mM, ready-to-use aqueous solution (i.e. no dilution is necessary). CDP-Star functions on both neutral and positively-charged nylon, giving the reagent added application versatility.

Features and Benefits

CDP-Star® is supplied as a 0.25 mM ready-to-use aqueous solution for use in a variety of membrane-based applications. CDP-Star functions on both neutrally-charged and positively-charged nylon, giving the reagent added application versatility.

Caution

Store at 2-8 °C protected from light.

Protocols

10x Blocking Buffer Protocol

Membrane-based blotting applications that employ enzyme conjugates to generate colorimetric or chemiluminescent signal require the use of an added blocking step to decrease the signal generated by non-specific binding.
