>>We have been experiencing a consistent loss of peak height intensity and
>resolution in 30bases in the 250-300bp region. We see this on every gel
>and in every sample. After that region the intensity and resolution
>improves and we can usually read out to 600-700bp. We have seven 377's,
>which we run 2-3 times/day doing 4 hour runs with 29:1 gels and we see
>it on every gel and it doesn't matter which chemistry we are running.
>This week we will be doing a series of experiments, on the reverse side
>of the plates, which will hopefully isolate the reagent(s) which are
>causing this problem of build-up on our plates. Our second problem is
>restoring the original side of the plates.
>I have heard that MultiTerge is meant to fix this problem, but we cannot

>>Does anyone have any ideas on what is causing this effect and how to
>eliminate it? Are there alternatives to MulitTerge?
>>Any sugeestions are very much appreciated!
