HYDROGEN PEROXIDE MACRO SENSOR

Direct quantitative measurements of hydrogen peroxide in biological samples

Despite the recognized importance of this oxidant in biology, real-time measurements at low concentration have been difficult. The hydrogen peroxide sensors developed by WPI are designed to compliment existing high sensitivity fluorescent approaches with direct quantitative measurement in biological samples in the low nM range.

Applications

  • Cell Cultures

 

The ISO-HPO-2 is a 2.0 mm stainless steel sensor, with replaceable membrane sleeves (600012) and an internal refillable electrolyte (100042). It is designed for use in cell cultures and similar applications.

The ISO-HPO-100 is a 100 µm tip diameter hydrogen peroxide micro sensor designed for use in tissues and similar applications. The design is based on a platinum wire sensing electrode coated with a proprietary membrane to enhanceH2O2 detection.

These sensors incorporate WPI’s proprietary combination electrode technology whereby the hydrogen peroxide sensing element and separate reference electrode are encased within a single Faraday-shielded probe design. This design has been shown to enhance performance during measurements and minimizes overall sensor size.

Our hydrogen peroxide (H2O2) sensors work with the TBR4100 and TBR1025 free radical analyzers.

NOTE: The 2mm biosensors come with a spare membrane sleeve, 1 cc syringe, an MF28G67 MicroFil needle and 10 mL of filling solution.

Hydrogen peroxide in biological systems

Hydrogen Peroxide is produced in biological systems by controlled pathways at low concentrations that impact on cell signaling. At higher concentrations inflammatory cells produce local intense amounts of this oxidant to kill pathogens. In the progress of human disease, uncontrolled formation of hydrogen peroxide from the mitochondrial respiratory chain and enzymes, such as xanthine oxidase, can occur (Prof. Victor Darley-Usmar, Univ. of Alabama, personal communication).

Dummy Load Resistor Kit

Analyzers, Amplifiers, Instruments/Platform, Stimulators, Stimulator Accessories
A365 can be used as a precise voltage source by placing a precision “dummy” resistor load across the output terminals. Precision resistors (such as the 100 Ω, 1000 Ω and 10,000 Ω resistors in WPI’s optional Dummy Load Resistor Kit #DRL) when placed across the output terminals convert the precision current levels to accurate voltage levels. For example, 1 milliampere flowing through 1000 Ohms will produce 1 volt across the output terminal pair. Thus, models A365D and A365R can be used as low noise sources of accurate voltage pulses or DC. To maintain less than 1% error, avoid shunting the output dummy resistor with a load resistance less than 100 times the dummy resistance value.
