Specificity of the ricin A chain-ribosome interaction was demonstrated by competition experiments using either ricin A chain or gelonin, another ribosome-inactivating protein having the identical mechanism of ribosome inactivation (26) in a broad spectrum of species including rat and rabbit (12, 26).
Report Abuse. I would say that bread stays fresh in the fridge for about a week. If you are unable to eat alot of bread at one time,then it is best to store your bread in the freezer,because the freezer keeps your bread for a longer period of time than the fridge does! ;-).
