Description
Alkaline Phosphatase (ALP) Assay Kit: The Essential Bio-Marker for Multi-Organ Health
Alkaline Phosphatase (ALP) is a hydrolase enzyme responsible for removing phosphate groups from many types of molecules, including nucleotides and proteins. Found most concentrated in the liver, bile ducts, and bones, ALP levels are the diagnostic “gold standard” for identifying biliary obstructions and bone-forming activity. Our ALP Assay Kit utilizes a kinetic colorimetric method to provide laboratories with high-speed, reliable data.
Diagnostic Power: Liver vs. Bone
An ALP test is vital for clinicians when patients present symptoms of liver or bone disease.
- Hepatobiliary Monitoring: Highly elevated ALP levels often indicate blocked bile ducts (obstructive jaundice), cirrhosis, or liver cancer.
- Bone Health Assessment: Increased levels are observed during bone healing, Pagetโs disease, rickets, and osteomalacia due to increased osteoblastic activity.
- Pediatric Growth: The kit is calibrated to handle the higher physiological ALP levels typically found in growing children and adolescents.
Key Technical Advantages
-
Optimized Buffer System: Uses an AMP (2-amino-2-methyl-1-propanol) buffer to maintain the ideal pH (10.4) for maximum enzyme catalytic activity.
-
Metal Ion Activation: Contains specific concentrations of Zinc and Magnesium ions, which act as essential cofactors to ensure full enzymatic recovery.
-
Minimal Interference: Advanced formulation protects against common interferences such as Bilirubin (up to 40 mg/dL) and Hemoglobin.
-
Kinetic Precision: Measures the rate of p-Nitrophenyl phosphate conversion to p-Nitrophenol at 405 nm, ensuring linear and reproducible results.
