Hi there,

I really like the Instant Blue stain, but sadly the new lab I have just joined have said it is too expensive

Having worked in a reagents company before, I know that a lot of products are simply the commercialisation of established and often long forgotten methods. So, it is with a hopeful heart that I ask you all....


...... yes, you've guessed it.....


does anyone know of any method/protocol which emulates this product, even in a limited way?


PS - I agree that the good old coomassie is fine, but what is not fine in a massive proteomics facility is having all that methanol and acetic acid swishing around our benches, apparently!

which stain does your new lab use?

It is going to switch to a stain-free imaging system, but we need something as a back-up for when that goes down. Further, the frgging machine is taking ages to get installed.

you can try a colloidal coomassie method. no methanol or acetic acid. the coomassie is made in ammonium sulfate solution and destains with water (if my memory is correct).
