| + | *<p style=”text-align:justify;”>This evening we had a wonderful idea to try to solve our problem in screening the new biobricks in LB plates. While we wait the new primers to arrive, we decided to use pGEM T-easy vector as a way to add the ''EcoR''I restriction site in the PCR products that already have ''Xba''I and ''Spe''I sites. This strategy will permit the part to be ligated to the biobrick vector avoiding unwanted ligations between the cohesive ends and consequently the hard screening we were performing. Click [https://2009.igem.org/Team:UNICAMP-Brazil/Protocols/pGEMStrategy here] to see the hole strategy.</p> | ||

| - | * | + | *<p style=”text-align:justify;”>So today we started digesting both PCR products and pGEM vector using ''Spe''I. We believe that this digestion will facilitate the correct insertion of ''Xba''I end besides ''EcoR''I site. After digesting, we did the ligation reactions, transformed and plated it in LB+AMP+X-gal medium. We hope that tomorrow we will find few blue colonies and a LOT of white ones! =]</p> |

| + | |||
| + | * After successfully digesting both insert and vector with ''Xba''I and ''Spe''I restricion enzymes, we performed today the ligation between them, according to [https://2009.igem.org/Team:UNICAMP-Brazil/Protocols/T4_DNA_Ligase Protocol 11]. | ||
| + | * As we purified both sequences, we really expect an correctly ligation this time, hence resulting in no religation between the vector and it's part (RFP device). | ||
