Membrane Comb

To all sequencers,
    I have tried the membrane comb (a couple of times) put out by The
Gel Company and am having some difficulty  getting reads past 400 bp.
    I am using a 377, big dye and the gel pack put out by Mandel. The
wtr is 36 cm, regular 2* run.
    I would run the temperature on the plates so as to reach 51 C, put
the membrane comb  on the top of a dry gel, apply the buffer and do a 10
min pre run after which I would start the run.
    The other difficulty is the applying of the comb to the dry gel.
After applying the sample to the wells, I wait 10 min. I apply
compressed ultra pure gas to  the surface of the gel to dry it out. I
still get some wells that compress  and do not touch the gel.

Any help would be greatly appreciated.
