Shape of 70,000 Da dextran

[Dr. S. Shapiro]

Dear Colleagues;

I need to know what is the approximate shape and approximate 
dimensions of a 70,000 Da dextran molecule dissolved in water.  What is
the volume formula for the geometric shape that comes closest to describ-
ing this dextran?  Any references/citations would be very much appreciated.

Kindly direct your response to me _directly_ at

because I rarely access this usegroup.

Thanks in advance to all responders,
