Manfred,
	We have tried this with labeled primers with mixed success.
The main problem was that template concentration needed to be optimized
and getting beautiful, intact template can be a chore.  Doug Berg with
the group at BRL and Palazzolo at LLB have done some studies. 

Try looking at:

 Phadnis, S.H., Huang, H.V. and Berg, D.E., Proc. Natl. Acad. Sci. USA 86,
 5908-5912 (1989).

 Strathmann, M., Hamilton, B.A., Mayeda, C.A., Simon, M.I., Meyerowitz,
 E.M.and Palazzolo, M.J., Proc. Natl. Acad. Sci. USA 88, 1247-1250 (1991).

for some ideas and suggestions (even these papers used radio-labeling).

Cheers.....bruce
