Analysis of TCRβ rearrangements in Jβ1^ω/ω and Jβ1^M2/ω αβ T cell hybridomas

Hybridoma	Total no.	Allele	No. with rearrangements
			GL	DJ	VD	V(D)J
Jβ1ω/ω	50	ω	0	34	0	16
		ω	0	0	0	50
Jβ1M2/ω	106	ω	0	1	0	105
		M2	83	0	22	1

TCRβ allele configuration in T cell hybridomas was determined by Southern blot analysis of HindIII- or EcoRI-digested genomic DNA by using probes C, D, and E (Fig. 3A). GL, nonrearranged.
