Materials

Material Name Type Company Catalogue Number Comment
AA-dUTP   Sigma A0410 5-(3-aminoallyl)-2’deoxyuridine-5’-triphosphate
dNTP   Amersham 27-2035-01 100 mM dNTP Set PCR grade
Random Hexamer primers   Amersham 27-2166-01 3mg/mL
SuperScript III RT   Invitrogen 80800444 200U/μL
CyDye™   Amersham RPN5661 Post-Labelling Reactive Dye Pack
QIAquick   Qiagen 28104 PCR Purification kit
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.
