Cross-Linked Molecular Weight Markers

[Marc Domanus]

Does anyone know of a high molecular weight protein marker for use with
SDS-PAGE that has a range between 100,000-500,000 Da?

     I have tried Sigma’s phosphorylase b cross-linked rabbit marker
(P8906) and am only able to see the 97,400 monomer.  The dimer which
should contain 28% overall intensity is not visible.  Any suggestions?

Thank you,
