Alkaline Phosphatase Antibody Conjugates

Leverage the robust and long-lasting signal of CST Alkaline Phosphatase (AP) conjugated antibodies to detect key proteins requiring prolonged signal development or long-term storage. By catalyzing phosphate removal from various substrates, AP conjugates produce a detectable signal via colorimetric, fluorescent, or chemiluminescent methods, offering high sensitivity through signal amplification.

Attributes

Alkaline Stability: AP works best at alkaline pH (9.5–10), making it ideal for assays requiring specific buffers or conditions unsuitable for HRP.

Resistance to Inhibitors: AP is resistant to common inhibitors like sodium azide, providing greater flexibility in your experimental conditions.

High Sensitivity: AP amplifies the signal by converting multiple substrate molecules, enabling the detection of low-abundance target proteins or antigens.

Long-Lasting Signals: AP provides stable signals, which benefit assays with delayed detection and extended signal development.

Applications in Research

Alkaline phosphatase antibody conjugates can be used with multiple detection modes for your research:

  • AP catalyzes the conversion of substrates like BCIP/NBT and pNPP into a visible, often colored precipitate. These signals can be visualized directly or quantified spectrophotometrically.
  • Alkaline phosphatase antibodies are commonly used with chemiluminescent substrates, such as CSPD and CDP-Star, which emit light upon reaction. This light can be detected using sensitive imaging systems.
  • AP can also be used with fluorogenic substrates, expanding versatility by enabling signal detection in fluorescence-based assays.

With so many signal potentials, alkaline phosphatase-labeled antibodies can be applied in numerous experimental setups, including:
