*This program calculates GC content or amino acid contents.
*It also calculates the molecular weight of the peptide.
*It also estimate the electric charge of the peptide from the number of K, R, H, D, and E.
*In calculating the molecular weight of input amino acid sequence, we refer to this table.
*If "Protein concentration" is selected and (A280) is input, concentration of protein solution will be calculated.
Calculation of concentrations are based on the method of:
1995, Prot. Sci. 4:2411-2423, C.N.Pace et al. and
1989, Anal. Biochem. 182:319-326, Gill and Hippel.
