CMC or carboxymetilcelulosis is used in order to prepare a gel to be used internaly. Iradiation reduces the gels properties and heat would destroy the other ingredients (no more than 60 degrees C).
Hello Victor,
Greetings from Colombia
You should try sterilize in a ultrasonic cleaner that kills the cells by membrane disruption.
I hope i have been helpful.
Good luck
u can use alcohol then rinse the sample with PBS, hope this will help, good luck.
ETO sterilization is one of the good method. you can rinse in PBS before use
