Schlierens or Swirls in PolyAcrylamide Gradient Gel

Hi Duncan, the glass is washed in RBS followed by several DI rinses.
I wonder about the temperature of the glass, versus the reagents/Room
temperature. I believe these artifacts are just on the surface of the
gel, as they are very difficult to see. However Lab personnell spend a
lot of time looking for them and discarding those they find.
Thanks for your help

It sounds like possibly insufficient mixing of the high and low in the
gradient mixer so you randomly get a slug of low or high acrylamide
where it shouldn't be?
Can you stick a dye or something in one side and make it more visible to
see the problem as it happens?
I love deadlines. I especially like the whooshing noise they make as
they go flying by.
