Lam B deletion co[ . . . ]d [?] by F' plasmid [mark to note, Do you have anything corresponding to the above? The better characterized the bounds of the deletion and of the plasmid the better. And I'd be just as happy if the stock were lambda minus but that's not crucial.]
Dear Barbara
Thank you for your note on "K-12."
Is Bruce Stocker's K-12 lyophil dated? Is it derivative of my collection, or of Clifton's aboriginals?
I will certainly pass on any further gleanings I can get out of my own records.
Many thanks.
Yours.
Joshua.
