[RASMB] Am I missing something?

[Walter Stafford]

Hi Dror,
	You can double your through-put by putting samples into both 
sectors of a single cell and collecting intensity data. There are at 
least 2 programs that can process intensity data into 
pseudo-absorbance data: SEDFIT by Peter Schuck and SEDANAL by 
Sherwood & Stafford can both handle intensity data in various types 
of analysis.

>Dear all,
