Fetal bovine serum (FBS), Hank's balanced salt solution (HBSS), Dulbecco's modified Eagle's medium (DMEM), phosphate buffered saline (PBS), Media 199 and penicillin/streptomycin amphotericin B were from Lonza BioWhittaker (Verviers, Belgium) and hydrogen peroxide (H202) was from Merck (Whitehouse Station, NJ, USA).
The recovered fibers were bleached with the H202 by suspending in a solution containing 16% [H.sub.2][O.sub.2] (v/v) and 5% NaOH and agitated for 90 min at 5.5[degrees]C.
For use in isolators, the material of the innermost bag has to meet a further requirement: it must be impermeable to H202 vapor to ensure this universally used bio-decontaminant will not be transferred on the culture media and inhibit microbial growth after sampling.
In this study, both the tolerant genotypes had lower H202 content and electrolyte leakage under drought stress than the susceptible genotypes SARA and TEVEE, while DH-2049 and HN7 (moderately tolerant cultivars) exhibited an intermediate response.
However, the H202 method is time-consuming, taking 270 minutes, compared to just 67 minutes for bleach cleaning.

Direct evidence for catalase as the predominant H202 removing enzyme in human erythrocytes.
Hydrogen peroxide (H202) and ozone therapies (03) are an integrative tool which uses the same free radical killing mechanism that the immune system uses to eradicate foreign invaders.
Briefly, sections (4 [micro]m thick) were rinsed in PBS for 30 min, digested with proteinase K 50 [micro]l (Tris HCl pH7.8 diluted) for 13 min, then incubated with 3% H202 in methanol for 17 min at room temperature to inactivate endogenous peroxidase.
The reaction was terminated by adding deionized water (500 mL) followed by adding H202 solution (40 mL, 30%).
