MitoFit Preprints Submit your preprint to MitoFit Preprints and increase awareness of your research::

Journal articles that were uploaded as preprints before being published gather more citations in the long run than papers without a preprint version. The effect is immediate and long-lasting.

Bioblast alert 2020(17) - H2O2 flux: 2020-11-30

Background H2O2 calibration in the Amplex® UltraRed (AmR) assay:

A background H2O2 calibration is performed before addition of sample. This is required for (1) calculation of the chemical background fluorescence in our Excel analysis template, and (2) calculation AmR assay sensitivity, for quality control.
- »Background H2O2 calibration« 

Why do we perform multiple H2O2 calibrations in the Amplex® UltraRed assay?

The sensitivity to H2O2 of the fluorometric signal changes during the experiment as a function of: (1) experimental time and accumulating UltroxRed (similar to resorufin), (2) changes of the optical properties due to titrations, and (3) the radical scavenging capacity of the sample. Therefore, H2O2 calibrations are performed before and after sample addition, and after selected titration steps.

Are permeabilized muscle fibers (pfi) a reliable model for studying ROS production?

High oxygen concentrations are needed to avoid oxygen limitation in pfi. However, high oxygen pressures may artificially increase ROS prodcution, including H2O2, making pfi a questionable model for ROS production.
