  • Nitrate Analysis - Laboratory Nitrate Test Kits

  • NECi - Model NTK-MPLR or NTK-MPSR - Microplate Format Nitrate Test Kits

    NECi - Model NTK-MPLR or NTK-MPSR - Microplate Format Nitrate Test Kits

    Use this kit for quantification of nitrate in essentially any aqueous sample.  Reactions occur on a 96-well microplate provided with the kit.  This test kit is based on the enzyme Nitrate Reductase (NaR), catalyzing the reduction of nitrate to nitrite using the natural electron donor NADH.  The nitrite reacts with color reagents under acidic conditions to produce a visible color. The concentration of nitrate in the original sample is...

  • NECi - Model NTK-TTLR or NTK-TTSR - Test Tube Format Nitrate Test Kits

    NECi - Model NTK-TTLR or NTK-TTSR - Test Tube Format Nitrate Test Kits

    Use this kit for quantitative nitrate analysis of essentially any aqueous sample, from wastewater to soil and plant extracts.  This test tube format kit is to be used with your colorimeter or spectrophotometer capable of reading at 540nm± 20nm.  NECi's recombinant Nitrate Reductase drives all Nitrate to Nitrite using NADH, which reacts with color reagents under acidic conditions to produce a visible color.

  • NECi - Model NTK-ND-25 and NTK-ND-100 - Nitrate Test Kits by NADH Disappearance

    NECi - Model NTK-ND-25 and NTK-ND-100 - Nitrate Test Kits by NADH Disappearance

    Use this kit to obtain quantitative nitrate data within standard range by measuring NADH Disappearance.  Measures nitrate content in food extracts and other aqueous extracts or samples.  Confirmed by NECi to provide accurate results when used in conjunction with Carrez's Reagent in meat, milk, and whey.  Use your standard food sample preparation method or see product documents for more information.

  • NECi - Model NaRA-10 - Nitrate Reductase Activity Assay Kit

    NECi - Model NaRA-10 - Nitrate Reductase Activity Assay Kit

    This kit enables you to prepare extracts of 10 samples and to assay these extracts for NADH: Nitrate Reductase (NaR) activity in roots, stems, leaves, whole plants, fungal or microbial extracts.  The enzyme Nitrate Reductase (NaR) catalyzes the reduction of Nitrate to Nitrite using the natural electron donor NADH.  The nitrite reacts with color reagents (dyes) under acidic conditions to produce a visible magenta color.  The color...
