Plant Ammonium Nitrogen Content Assay Kit

Determination of Significance: Nitrogen is an essential element of living organisms. Ammonium nitrogen enters plant cells and forms amino acids or amides. Ammonia nitrogen content in plant tissues can reflect the degree of plant stress. Measurement Principle: Alpha - amino acid can react with hydrated indene triketone to forms blue-purple compound which has characteristic at 570 nm. The amino acid content was calculated by measuring absorbance at 570 nm. Self Provided: Spectrophotometer/ microplate reader, micro glass cuvette/96 well flat-bottom plate,?transferpettor, water bath, desk centrifuge, mortar/ homogenizer, anhydrous ethanol, ice and distilled water.
