Figure 1.  Normal blast cells express very little Qa1 as judged by staining with the Qa1-specific mAb 4C2
		Cells	Stained with

		Blasts	Med
		Blasts	anti-Qa1
Conclusions
1.  Wild type L cells express no detectable Qa1 [and lack transcripts for Qa1]
2.  L cells transfected with Qa1 [LQ cells] express high levels of Qa1
3.  Normal ConA blasts express levels of Qa1 that are barely detectable with the mAb 4C2
