Biologists always use symmetric LacI-family operators, e.g. AATTGTGAAC GTTCACAATT (O44) and AATTGTAAGC GCTTACAATT (O22). Please notice that they are all 20bp long and each right half of 10bp-long strand’s complementary strand is reversed symmetric with its left half of 10bp-long strand. For short we call this kinds of symmetrical operators as Oxx, for example, O44, O22, etc. Then you must have already understood what O24 means-- Yes, it means the asymmetric operator AATTGTAAGC GTTCACAATT (O24), which has the 10bp-long strand of O22 for its left half sequence and the 10bp-long one of O44 for its right half sequence. Again for example, O42 means AATTGTGAAC GCTTACAATT (O42), and so on. We also give these asymmetric operators another name: Hybrid Operators.


For convenience, I listed the sequences we've used:


Symmetric Operators

   O11 AATTGTGAGC GCTCACAATT
   O22 AATTGTAAGC GCTTACAATT
   O33 AATTGTAAAC GTTTACAATT
   O44 AATTGTGAAC GTTCACAATT
   O55 AATTTTGAGC GCTCAAAATT
   O66 AATTATGAGC GCTCATAATT
   O77 GACGACTGTA TACAGTCGTC


Asymmetric Operators

"Ox6", "Ox7" and "O6x"
