Unamplified mRNA abundance in miR-124 and mock-transfected cells


ABSTRACT: To compare total RNA levels in miR-124 and mock-transfected cells (Figure S3), 5-10 ug of total RNA from miR-124-transfected cells or mock-transfected cells or universal reference RNA (Stratagene Cat# 740000) was reverse transcribed with Superscript III (Invitrogen Cat# 18080085) in the presence of aminoallul-dUTP 5-(3-aminoallyl)-dUTP (Ambion Cat# AM8439) and natural dNTPs (GE Healthsciences Cat# US77212) with 10 ug of N9 primer (Invitrogen). Subsequently, amino-allyl-containing cDNAs from miR-124 and mock-transfected cells were covalently linked to Cy5 NHS-monoesters, and universal reference cDNA was covalently linked to Cy3 NHS-monoesters (GE HealthSciences Cat# RPN5661). Cy5- and Cy3-labeled cDNAs were mixed and diluted into 50 ul of solution containing 3x SSC, 25 mM Hepes-NaOH (pH 7.0), 20 ug human Cot-1 DNA (Invitrogen Cat# 15279011), 20 ug of poly(A) RNA (Sigma Cat# P9403), 25 ug of yeast tRNA (Invitrogen Cat# 15401029), and 0.3% SDS. The sample was incubated at 95 C for 2 min, spun at 14,000 rpm for 10 mins in a microcentrifuge, then hybridized at 65 C
