Kaupapa:

Ko te waikawa 4-hydroxyethyl piperazine ethyl sulfonic he arai koiora; Ka taea te wehewehe me te tātari i te arai wāhanga RNA, te arai, te arai whakarōpū i mua i te tauhohenga; Whakamahia mō te tohu RNA me te T4RNA ligase 3'-terminal; Whakamahia i roto i te kete tātaritanga matū koiora, te kete tango DNA/RNA me ngā kete tātaritanga PCR. Hei āwhina i ngā pūtau kore pangia kia mahi. He momo arai katote hauwai, ka taea te whakahaere i te whānuitanga o te uara pH o te pūmau mō te wā roa. Whakamahia te kukū whakamutunga o te 10-50 te tikanga mō te L, ka taea te whakatutuki i te kaha arai LHEPES whānui kei roto te 20 te tikanga.
