Full-thickness vessel wall samples from ruptured IA domes and MMA were prospectively collected from patients undergoing microsurgical clipping
Extracted molecule
total RNA
Extraction protocol
The total RNA was extracted by Trizol Reagent, and DNase digestion.
Label
Cy3
Label protocol
miRNA molecular in total RNA was labeled by miRNA Complete Labeling and Hyb Kit(Cat#5190-0456, Agilent technologies, Santa Clara, CA, US)followed the manufacturer’s instructions, labeling section.
Hybridization protocol
Each slide was hybridized with 100ng Cy3-labeled RNA using miRNA Complete Labeling and Hyb Kit(Cat#5190-0456, Agilent technologies, Santa Clara, CA, US)in hybridization Oven(Cat#G2545A, Agilent technologies, Santa Clara, CA, US)at 55℃，20rpm for 20 hours according to the manufacturer’s instructions, hybridization section. After 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).
Scan protocol
Slides were scanned by Agilent Microarray Scanner(Cat#G2565BA，Agilent technologies, Santa Clara, CA, US)
Description
