[RASMB] Density of HEPES

[lelj at interchange.ubc.ca]

Hello to all the RASMB'ers,

Does anyone know the appropriate polymomial fit coefficients to calculte the density value for HEPES? I use 20mM concentration and different salt concentration at 20C. 
I need to calculte the sigma to put in WinNONLIN. 

Thanks in advance
Barbara
