IAA Research Platform

Product Code: imFlux-IAA-100

Part of the NMT BioFunction Research Platform series. The imFluxes-IAA-100 is used for testing living organisms’ physiological functions, and it is designed specifically for testing IAA, a class of plant hormones.

While maintaining the integrity of the samples, it can detect IAA influx and efflux and has sensitivity as high as femto (10-15) moles • cm-2 • s-1.

Currently, imFluxes-IAA-100 is the only real-time and dynamic information system for testing IAA in the world.

This platform would be beneficial for research in areas such as growth regulation, polar transport and herbicide mode-of-action



  NMT Reveals Functions of IAA in Potential Cancer Treatment

In-situ and non-invasive test on living samples

Provides information of samples in their normal physiological condition without damaging the samples

Real-time Testing

Can test and provide real-time data in as little as 5 seconds

Ionic and molecular measurements

This platform measures: IAA

Additional sensor options: none

(Other NMT BioFunction Research Platforms are able to measure Ca2+, H+, K+, Na+, Cl-, Mg2+, Cd2+, NH4+, NO3-, O2, H2O2, and/or IAA)

Long-term measurements

Can provide real-time and dynamic detection for many hours

No labeling

Without using the radioactive, chemical, pharmacological or other labeling methods, imFluxes-IAA-100 allows researchers to detect the tested ions and molecules in advance in a safe and environmentally friendly manner.

High resolution and wide range of sample sizes

Temporal resolution: 3s (response time) and 5s (measurement time);

Spatial resolution of ions: 1µm- 10µm;

Spatial resolution of molecules: 20µm—25µm;

Flux Sensitivity: 10-15mol•cm-2•s-1

No need to extract samples

Can detect samples directly without using grinding and other traditional extraction methods

Capable of testing various samples

Intact organisms, organs, tissues, cells, and even small condensed organelles can be tested

3D Flux Measurements

Different platforms in the NMT BioFunction Research Platform series can detect one-dimensional measurements (NMT BioFunction Research Platforms are the exception, for they can detect three-dimensional measurements).

After upgraded, all platforms in the series can detect three-dimensional measurements and provide flux information by measuring the concentration gradient in all x, y, and z directions. At the same time, sample positioning will become more precise and flexible, thus enhancing the repeatability of the experiment.
