- by Lars Henrik Oestergaard©1994.

- Introduction:
- This HyperCard stack estimates the molecular weight
- and "the isoelectric point" of an amino acid sequence.
- The stack is absolutely free, and you may give copies of it to
- everybody. However, do not make anybody pay for it.
-
- Input:
- Enter the amino acid sequence manually or use the import
- function to import it from a text file. Make sure there is no
- blanks before or after the sequence. Press the calculation
- bottom before heading on to the MW & pI calculations.
-
- Output:
- The MW calculation are obvious. When hitting the calculation
- bottom for the pI calculation you will be requested to enter the
- pH range you want to investigate (and the number of points). As
- the calculations are slow, try to limit the number of points and
- instead narrow the interesting pH interval stepwise. The calulated
- data is not being plot in a graph, but you may export them to a
- text file. And then plot the data by a graphing programme (excel,
- kalaidagraph...).
