0.25 mM solution (0.124 mg/ml), ready-to-use, colorless solution

CDP-Star is a chemiluminescent substrate for alkaline phosphatase that enables fast, ultra-sensitive detection of biomolecules by producing extremely rapid visible light. Light emission is recorded on X-ray film or on luminescence imager systems.

• Save time with a fast, ultra-sensitive substrate.
• Easily strip and reprobe membranes.
• Take multiple exposures of up to two days for each experiment.

Reuse the substrate by filtering and storing in sodium azide.

Nota de preparación

Storage conditions (working solution): Washing Buffer: 15 to 25 °C, stable
Maleic Acid Buffer: 15 to 25 °C, stable
Detection Buffer: 15 to 25 °C, stable
Blocking Solution: always prepare freshly
Antibody Solution: 2 to 8 °C

Otras notas

• First exposure to X-ray film should be 5-15 minutes. Examine film and then determine other exposure times based on initial result.
• No preincubation step required.
• Apply substrate quickly to avoid gray shadows from substrate drops and drying of membrane (leads to uneven, high background).
• Do not use plastic wrap to cover blot; use hybridization bags, acetate sheet protectors, or two sheets of transparent film.
• Exposure times are shorter than with CSPD.
• Do not use nitrocellulose membranes.

Repeat exposures can be made up to two days after the addition of substrate.

For life science research only. Not for use in diagnostic procedures.
