Abhijeet Singh Not all bacterial toxins are proteins. For instance, some are lipids (e.g., lipid A, in the outer membrane of gram-negative bacteria is an endotoxin).
Sahar Mohammed Jawad From my reply (above) to Abhijeet, you can already guess that your question is too vague. The methodology you need to employ will depend (a lot) on the type of bacterial toxin you want to study. So, you need to be more specific.
Sure! There are exceptions every where. And when you say "some" that would still mean a majority of toxins would be / are proteins. We both can agree to that.
But agreed more to the second point that to get proper answer one must ask logical question or at least put some efforts in explaining problems. Many of the people ask questions here because they don't want to be bothered and like to be spoon fed.
Have a look here, if one can't find answer to a simple question in over a year, spoon feeding is a small expression for that person
answers without getting tired, or as I expressed it feed with the prepared spoon, if you don't want the answer or there is no need, and despite that your answer was poor.
