Northern blot analysis of the XG and MIC2transcripts from transfected RAG clones and somatic hybrid derivatives.

Twenty micrograms total RNA from the different cell lines were hybridized under high-stringency conditions with either the XG(A) or MIC2 (B) cDNA probes. Identical amounts of RNA were deposited in each lane, as determined by densitometry analysis of ribosomal RNA under ultraviolet light illumination (not shown).
