pNPP Phosphatase Assay Kit

产品说明

一般描述

Para-nitrophenyl phosphate (pNPP) is a chromogenic substrate for most phosphatases such as alkaline phosphatases, acid phosphatases, protein tyrosine phosphatases and serine/threonine phosphatases. The reaction yields para-nitrophenol, which becomes an intense yellow soluble product under alkaline conditions and can be conveniently measured at A₄₀₅ nm on a spectrophotometer.

特点和优势

• No wash or reagent transfer steps are involved. The assay can be completed within 30 minutes.
• Compatible with high-throughput handling systems.

适用性

The kit is suitable for the quantitative determination of phosphatase activity of protein phosphatases.

原理

The pNPP Phosphatase Assay kit involves adding a single reagent to the phosphatase and measuring the product formation on an absorbance reader. The assay can be conveniently performed in cuvettes, tubes or multi-well plates at either room temperature or 37 ℃.
