P4G13_trigger_5_phi29
P4G13_trigger_5_phi29 (BBa_K4438709) is single-stranded DNA having 26 nucleotides . Figure 1B) shows the secondary structure and minimum free energy.
Usage and Biology
The part P4G13_trigger_5_phi29 (BBa_K4438709) is complementary to the part P4G13_aptamer (BBa_K4438700) with few mismatches. It blocks the entire binding region of the progesterone aptamer [1]. Figure 1D) Shows the secondary structure of both parts hybridised at 37° Celsius. Progesterone binds with P4G13_aptamer (BBa_K4438700) with high affinity and displaces the P4G13_trigger_5_phi29 (BBa_K4438709) [2]. This part has complete complementarity with part P4G13_Target_5 (BBa_K4438710) . Phi 29 DNA extension polymerase extends the template strand and in-vitro transcription of the duplex forms multiple broccoli light-up aptamers. Different levels of progesterone can be detected using all these three parts.
