The ZP Active Glucose Formulation is a proprietary formulation for use in manufacturing glucose strips.
The formulation is:
1) Designed to work at low voltage so avoides common interference molecules.
2) Contains an enzyme specific to glucose so ensuring specificity.
3) Contains stabilization agents for good shelf life when dried down.
4) Contains a mediator that acts both as the mediator for the enzyme and as a redox couple for the reference electrode.
5) 1 L can produce 2.5 million glucose strips.
6) Optimized for use with the Biodot range of printers/dispensers.
7) Works with glucose strips in the two and three or more electrode mode.
8) Works with amperometric and coulometric glucose assays.
9) The ZP Active Glucose formulation eliminates the need to support QA/QC for formulating glucose enzyme formulations.
10) The cost of the formulation is 0.0056 cents per strip.
Please contact ZP before purchasing this product. This product is for people developing CGM type sensors.
Store in freezer (-20 degC) for long term storage and in the fridge for short term storage (4 to 8 deg C).
Please note you will also need a barrier layer solution if using this product, if you on the ZP Academy.
Product contains enzyme solution and cross-linking solutionl. We ship either: 1 ml of enzyme solution plus 0.25 ml of crosslinker or 5 ml of enzyme solution plus 1.5 ml of crosslinker or 50 ml of enzyme solution plus 12.5 ml of crosslinker, depending on option chosen.
CGM - ACTIVATION SOLUTION - Please contact ZP before purchasing this product. This product is for people developing CGM type sensors.
ZP CGM Activation Formulation (non-enzyme loaded). This formulation is for people who want to dilute the ZP glucose catalyst solution. ZP has kept this solution identical to the ZP glucose catalyst solution but we have replaced the glucose enzyme catalyst with an inert protein.
BARRIER LAYER SOLUTION - Please contact ZP before purchasing this product.
LACTATE ACTIVATION SOLUTION - Please contact ZP before purchasing this product. This product is for people developing lactate type sensors.
Performance of the solution.
Zimmer and Peacock has electrochemically and functionally characterized the solution. We have assumed that the electrochemical assay type will be amperometric.
From a voltammetric investigation we have determined the bet voltage with which to perform an amperometric assay using the ZP Glucose Strip Active Formulation is -200 mV vs Ag/AgCl/0.15Cl-, or -350 mV a carbon RE, i.e. if your reference electrode (RE) is silver/silver chloride the assay should be run at -200 mV, but if the RE is carbon is should be -350 mV vs. RE.
ZP has electrochemically characterized the solution on one of our carbon electrodes - A-AC-CAC-203-N
Zimmer and Peacock has characterised the performance of the formulation, again on A-AC-CAC-203-N, where the glucose concentration has been varied.
From the raw data we can recommend an integration of the current between 1 to 5 seconds will give the signal.
