Notes
Bulk hydrophobicity and isoelectric point calculations are approximate at best, because they ignore several important factors, not the least of which is protein folding. More precise calculations are theortically possible, but would take thousands of hours on a personal computer and are rarely worth the effort. Several isoelectric poinot calculations exist because different researchers have advanced different values of pKa to be used in the calculations.
