abstract |
The present invention provides an immobilised pH gradient (IPG) gel that is more uniformly reswollen than currently available gels. Furthermore, the improved IPG gel of the present invention can be produced with larger pore sizes than their conventional equivalents. Accordingly, in its broadest aspect, the present invention provides an immobilised pH gradient (IPG) gel comprising an organic acid or organic base, wherein when hydrated, the IPG gel is substantially uniformly swollen along the pH gradient of the gel. |
