Amplite® Colorimetric Alkaline Phosphatase Assay Kit *Yellow Color*

Amplite® Colorimetric Alkaline Phosphatase Assay Kit

Yellow Color

Amplite® Colorimetric Alkaline Phosphatase Assay Kit *Yellow Color* is a colorimetric assay kit for quantifying alkaline phosphatase (ALP) activity in solutions, cell extracts, and solid surfaces.

Colorimetric detection: Uses pNPP to generate a yellow product measurable at ~400 nm.
High sensitivity: Detects ALP concentrations as low as 0.3 mU/mL after 30 minutes.
ALP-specific substrate: Uses pNPP as a chromogenic phosphatase substrate for activity measurement.
Mix-and-read workflow: Compatible with 96- or 384-well microplates and HTS liquid handling systems.
Applications: Suitable for ALP activity measurements in immunoassays, cell extracts, and blotting workflows.

Alkaline phosphatase dose response was measured with the Amplite® Colorimetric Alkaline Phosphatase Assay Kit in a white/clear bottom 96-well plate using a NovoStar microplate reader (BMG Labtech).

Overview

Alkaline phosphatase is a highly sensitive enzyme for ELISA, immuno-histochemical, Northern, Southern and Western blot applications. It is widely used in various biological assays (in particular, immunoassays) and ELISA-based diagnostics. This Amplite® Alkaline Phosphatase Assay Kit uses pNPP, a chromogenic phosphatase substrate, to quantify alkaline phosphatase activity in solutions, in cell extracts as well as on solid surfaces (such as PVDF membranes). The kit provides all the essential components with our optimized 'mix and read' assay protocol that is compatible with HTS liquid handling instruments.
