Web16 dec. 2016 · Fig. 9e shows the EPR spectrum of a frozen solution of hhMb in HEPES buffer where SDS was added to a final concentration of 9.5 × 10 −4 M. This spectrum also shows an LS contribution with g z = 2.95 ± 0.02 and g y = 2.265 ± 0.005 which are similar values to those found for the LS contribution in mesoporous TiO 2 incorporated with hhMb. Web3 sep. 2014 · 9. Many molecular biology protocols advice against sterilizing HEPES (4- (2-hydroxyethyl)-1-piperazineethanesulfonic acid) solutions by autoclave. Supposedly, HEPES is heat labile, and the high temperatures used for sterilization somehow impair the function of the buffer, or perhaps generate unwanted chemical species (this is speculation on my ...
