Why do you offer both a Cholera Toxin and Cholera Toxin (Azide Free)?
Many years ago customers requested or suggested that we provide cholera
toxin with azide. Azide prevents bacterial growth.
Over the course of years of producing cholera toxin, we have developed sterility techniques which allow us to offer the product without the azide and still maintain sterility.
Some customers use cholera toxin in animals and therefore would purchase the product without azide.
If you would like a recommendation of which cholera toxin to use, we would recommend the azide free
product. We continue to offer both versions of this product, as some customers are still interested
in continuing to use the form that they have used in the past.
