Protein Isoeletric point calculation

[Rafael Iosef Najmanovich Szeinfeld {S]

	Hi All,
	I read a recent message about Proteins Isoeletric point (PIP) and the 
replayer said something about a progam that calculates PIP's so I'll like 
someone to say something about the method used for such calculations, 
what are the simplifications an so on.
	Thanks for your help.
					Rafael.
