how do we access protein database?

[wiens at iscsvax.uni.edu]

Anyone please,

We would like to compare 6 decapeptide sequences to which we have antibodies,
to known protein amino acid sequences from a data base, but we haven't done it
before and don't know how to access a database such as Protein Data Base or
Gopher.  Could someone help?  We are on a pc hooked up to a university VAX and
are used to using internet.

Thanks,  Darrell and Jacqui
