    5 Pack Extra Enzyme Diluent Bulbs

    These packs are designed for users ordering nitrate reductase enzyme reagent packs greater than 1 unit of enzyme/vial to bring final concentration to 1 unit/ml.  

    This optimized nitrate reductase storage buffer is always recommended for reconstituting NECi's nitrate reductase for usage and storage purposes.  These diluent bulbs may be stored at room temperture, but we recommend storing at 4°C.

    When ordering nitrate reductase in 2, 3, or 5 units per vial, use 1 enzyme diluent bulb per unit to acheive 1 unit enzyme per ml of solution.  This is the recommended concentration for most nitrate assays.
