You can include urea in your gel to resolve ~5 kDa without using gradient gel. I am sorry that I forgot what was the percentage. Please take a look at "Gel Electrophoresis of Proteins: A Practical Approach". Or you can try the premade gradient gel from Invitrogen. http://www.invitrogen.com/etc/medi

If you want dictionary, atom naming and everything else about new compound names you can copy all "monomers" (in our definition) from: ftp://ftp.ebi.ac.uk/pub/databases/rcsb/pdb-remediated/data/monomers/components.cif.gz It has all compounds used in pdb with "idealised" coordinates, compound
