Hello there,
I post about the same question about a month ago, until now I haven't got
any creative suggestions and also could not solve my problem by myself. I
am frustrating here. I problem is:
I am using BIO-RAD mini-gel electrophoresis system. My target protein is
about 25-27 KD. I run 12% running gel and 4% stacking gel at 100 V. The
results I've got were curved and connected bands between lanes. First I
thought it might cause by high salt concentration in my sample, I diluted
my sample from 5 ug/ul to 3 ug/ul.The results got better but not good
enough. I still had curved bands and connections between lanes. It seems
like both ends of the bands migrate faster than the middle. 
Could anybody give me some advice? Thanks in advance!
