I have powdered forms of aflatoxins and want to prepare standard stock solutions of the toxins.
In certain papers a combination of benzene is given: acetonitrile (98:2) or chloroform: acetone is used for diluting.
I would like to make stock solutions of the toxins and dilute them whenever needed, so my question is what solvents can I use for preparing stocks and working standards?
I will be using the stocks for TLC and immunaffinity studies.
