I presented the H2 locus model at the Asilomar meeting. I should say that there were two other groups later that came to the same conclusion, one was Snell and Peter Demant and others, and another was Thorsby. We all agreed it was the right, correct interpretation and it was generally accepted so... very rapidly. So, at the Asilomar meeting there was... clear to everybody that there were some genes probably far apart which controlled antigens on erythrocytes and all kinds of other tissues. There were the classical H2 antigens and there, between them, was something unknown. One of them was the gene that controls some protein, which was of known function and the other was the IR gene, IR1 gene of McDevitt, and a number of other genes discovered by other... or genes... genes controlling other immune responses, mapping more or less into that same region. And that was what really electrocise... is that the right word?

[Q] Electrify.

Electrify, it's correct, sorry, electrified the audience and the immunologists and everybody realized well, there is something very... terribly important in the middle between these two genes and the question was what was it, what was it doing, how to get it?
