| Fa'amoemoe: | 4- hydroxyethyl piperazine ethyl sulfonic acid o se pa'u olaola; Le tali o le vavaeeseina ma le auʻiliʻiliga o le RNA vaega paʻu, paʻu, paʻu hybridization muamua; Fa'aaogaina mo le RNA ma le T4RNA ligase 3'- fa'ailoga fa'amau; Fa'aoga ile pusa su'esu'e fa'aola kemikolo, pusa fa'aaogāina DNA/RNA ma pusa fa'ama'i PCR. I sela e lei pisia e galue. O se ituaiga o hydrogen ion buffer, e mafai ona pulea le lautele o le pH tau o le tumau mo se taimi umi. Fa'aaogā le fa'atonuga mulimuli o le 10-50 tendency mo L, fa'aaganu'u lautele ala o lo'o i ai le 20 fa'atonuga LHEPES fa'apolopolo gafatia e mafai ona ausia. |
