Would anyone know how to stain proteins prior to gel-loading? I am looking for a homemade dye, i.e. Involving reagents that can be found in the lab and not by ordering from a company.

 

Thanks.

I guess you are looking for a coomassie type prestain? I do not use them myself, but you essentially you can use coomassie under acidic conditions to your sample. Check out Judd 1979 Analytical Biochemistry as an example.
