It's probably 'lambda' in capital letters (quite similar to capital delta). DE3 is a lambda prophage, hence the name.
Hope it helps, alejandro -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of WS Sent: Thursday, March 27, 2014 2:11 AM To: [email protected] Subject: E coli BL21?DE3 ? Dear colleagues, While in search for BL21(DE3) & friends, I discovered only some vials labelled "BL21ΔDE3" and some labelled "BL21ΔDE3pLYSE". I suppose that's just a mis-spelling and thus exactly what I'm looking for, as google yields exactly 1 hit for "BL21ΔDE3" and Pubmed doesn't return any, also when I'm checking for"BL21Δ(DE3)". And such a denomination doesn't make any sense to me, too, as DE3 is not part of the natural genotype. I'd appreciate any comments. Thanks!
