Hi,
I'have treated cell cultures with H2O2 (SIGMA cat# H1009) and the first time I obtained good results, but now it doesn't work anymore,,,, I'm wondering if there is something wrong in that kind of H2O2 or in my way of storage (aliquots at 4°C and dilution in water just before adding to the cells).
Can you help me?
Thanks in advance,
Roberta
