I'm using a 15% gel in a tris-glycine-SDS-PAGE system and I've extracted protein from live tissue but I seem to be getting no clear bands at all and just a smear. Even the markers don't appear crisp/clear. I've tried using a gel stain to visualize any protein following electrophoresis and it looks the same was as it does when i expose from the PVDF membrane.
Run Time ~ 3 hours
Voltage - 90Volts
The protein i'm looking for is approximately 20 kda
Any help would be greatly appreciated
