This probe is used for the detection of human Fas mRNA. Fas is a member of the family of cell surface receptors possessing a death domain. Binding of ligand to Fas results in a cascade of events culminating in apoptosis.1 Northern blot analysis reveals two transcripts for Fas mRNA, 1.9 kb and 2.7 kb in length, which are likely the result of alternative splicing.2 Treatment of HT-29 cells with IFNγ, or thyrocytes with IL-1β induces the expression of Fas.3,2 This cDNA probe is 55% and 47% homologous to the corresponding murine and rat sequences, respectively.
