Question Dissociation constant

Can anyone help me?
I am trying to purify a protein out of a nuclear extract. I know absolutely nothing about this protein (transcription factor), except which DNA sequence it binds to. I try to follow the purification through a gel shift (EMSA) assay and have heard that you can calculate the dissociation constant (Kd) from gel shifts.
Do anyone know how


I would be thankful for all your help!

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.
