Lab GelBank A public, web-accessible database that stores annotated gels produced from GelScape Accessible directly from GelScape Gel Images are stored as clickable HTML Image Maps Supports gel querying from level of organism, organ/tissue, Swiss-prot ID and protein name Relatively few entries so far
Lab Federated 2D Gel Databases Remotely queryable via the web Attainable through SWISS-PROT search Linked to other 2D databases via web Image mapped 2D gel spots to support graphical image query Directly reachable from within 2D gel analysis software Appel, R.D. et al. Electrophoresis 17: (1996)
