RNA was prepared using the RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany) following the manufacturer's recommendations and checked for a RIN number to inspect RNA integration by an Agilent Bioanalyzer 2100 (Agilent technologies, Santa Clara, CA, US).
Label
Cy3
Label protocol
Cyanine-3 (Cy3) labeled cRNA was prepared from 0.5 ug RNA using the Low Input Quick Amp Labeling Kit, One-Color (Cat.# 5190-2305, Agilent technologies, Santa Clara, CA, US) according to the manufacturer's instructions, followed by RNAeasy column purification (QIAGEN, Valencia, CA).
Hybridization protocol
Each slide was hybridized with 1.65ug Cy3-labeled cRNA using Gene Expression Hybridization Kit (Cat.# 5188-5242, Agilent technologies, Santa Clara, CA, US) in Hybridization Oven (Cat.# G2545A, Agilent technologies, Santa Clara, CA, US), according to the manufacturer’s instructions. After 17 hours hybridization, slides were washed in staining dishes (Cat.# 121, Thermo Shandon, Waltham, MA, US) with Gene Expression Wash Buffer Kit(Cat.# 5188-5327, Agilent technologies, Santa Clara, CA, US), followed the manufacturer’s instructions.
Scan protocol
Slides were scanned by Agilent Microarray Scanner (Cat#G2565CA, Agilent technologies, Santa Clara, CA, US) with default settings, Dye channel: Green, Scan resolution=5μm, PMT 100%, 10%, 16bit.
