Protocol

La reazione della trascrittasi inversa Girare blocco riscaldamento a 70-80 ° C e 42 ° C. Bagni di acqua può essere utilizzata anche in questo passaggio. Se si utilizza blocchi di riscaldamento, mettere un po 'd'acqua in modo che il calore è uniforme. Adescamento di reazione Prendete 3 g di RNA Regolare il volume a 13 microlitri con acqua RNasi libero Aggiungere 2,5 ml di casuale esamero primer (2mg/ml) Mescolare bene e i…

1M K2HPO4        
1M KH2PO4        
1M KPO4 Buffer     To make a 1M Phosphate buffer (KPO4, pH 8.5-8.7) combine: 9.5 mL 1M K2HPO4 and 0.5 ml 1M KH2PO4
Phosphate wash buffer Buffer     For 100 mL Phosphate wash buffer (5 mM KPO4, pH 8.0, 80% EtOH) mix: 0.5 ml 1 M KPO4 pH 8.5 + 15.25 mL MilliQ water + 84.25 mL 95% ethanol. Wash buffer will be slightly cloudy. ** IMPORTANT: Phosphate wash buffer should be prepared daily.
Phosphate elution buffer Buffer     Diluting 1 M KPO4, pH 8.5 to 4 mM with sterile water
Sodium Carbonate Buffer       (Na2CO3): 0.5M, pH 9.0. Dissolve 4.2 g NaHCO3 in 80 mL of sterile water and adjust pH to 9.0 with 10 N NaOH; bring volume up to 100 mL with sterile water. To make a 50 mM solution for the dye coupling reaction dilute 1:10 with water. Note: Carbonate buffer changes composition over time; make it fresh every couple of weeks to a month.
