pH & Isoelectric point Server

Compute the theoretical isoelectric point
Plot net charge vs pH in a range from 0 to 14
Obtain a text file showing net charge vs pH

Attention: This server uses a single protein chain
in a PDB struture. Alternatively, user can enter the
FASTA sequence. This server does not repair PDB structure
and will do nothing if the PDB structure is not readable



When using files generated by this server in a publication, please cite:
