In June 2011 the SIB ExPASy Bioformatics Resources Portal was launched by the SIB Swiss Institute of Bioinformatics. ExPASy has evolved, becoming an extensible and integrative portal accessing many scientific resources, databases and software tools in different areas of life sciences. Refer to Features for more details. The new portal enhances the original ExPASy server, previously known as "Expert Protein Analysis System"
Originally, ExPASy was created in August 1993: it was one of the first Web servers for biological sciences. Since that date it has undergone constant modifications and improvements. Please contact the ExPASy Helpdesk if you have comments or encounter problems when using it.
