>1.  is this method reliable?  How much protein is required for successful

Yes, the method is reliable. In general about 5 pmole for a N-terminus 
sequence of up to 40 aa

>2. can it be done from an SDS-PAGE gel as well as a native PAGE

In theory it can, as long as you are sure that what you get on the native 
PAGE is a single species of polypeptide.

>3. does anyone know of any companies with the sequencing apparatus that 
will>process the samples for you?

 I do know one here in the Netherlands, but 
there should be plenty of them in the States.

>Any references would be appreciated!

Good luck Ton
