Table pub.mgd.prb_probe
Defines an accessionable Molecular Segment object. Master table for all Molecular Segments: Single-stranded DNA or RNA molecules of specific base sequence, labeled either radioactively or immunologically, that are used to detect the complementary base sequence by hybridization.

Master for PRB_Marker, PRB_Reference.
