Useful Science links
These are the links I use everyday for my research.

• Pubmed - No scientist can survive without searching this database regularly.
• Pedro - We all know to visit this site for all our molecular biology needs.
• Protein Tools at ExPasy - Great tools for characterizing protein sequence. My favorite tool there is ProtParam.
• MS-Digest - Great program for determining all possible digest fragments for your sequence for several proteases. I especially enjoyed the user friendly interface.
• Swiss-Prot- Protein sequence and domain information.
• PDB - For all your protein structure co-ordinate needs. However, this database will soon be managed by a new group located at RCSB.
• NCBI - The site for access to Entrez for more sequence searching and Blast and Psi-Blast for homology searches and awesome multiple alignment.

• RASMB - General info and programs in studying reversible associations of macromolecules.
• Bo Demeler's UltraScan site - for info or download of his software for centrifugation data analysis.
