We evaluated the RNA integrity number (RIN) of cells from AP-positive fractions using an Agilent 2100 Bioanalyzer system. We selected three RNAs with a relatively high RIN value from each group and performed complementary RNA (cRNA) labeling and amplification using a Low Input Quick Amp Labeling Kit (Agilent Technologies, Santa Clara, CA, USA). We refined the cRNA labeling using RNeasy Mini spin columns (QIAGEN) and hybridized the cRNAs using a Gene Expression Hybridization Kit (Agilent Technologies).

Microarray experiments (n=3) were performed by OE Biotech Co., Ltd. Total RNA was extracted using TRIzol® (Invitrogen; Thermo Fisher Scientific, Inc.) and quantified using NanoDrop ND-2000 (Thermo Fisher Scientific, Inc.). RNA integrity was assessed using the Agilent Bioanalyzer 2100 (Agilent Technologies, Inc.). Sample labeling (Quick Amp Labeling kit; cat. no. 5190-2305), microarray hybridization (Agilent Gene Expression Hybridization kit; cat. no. 5188-5242) and washing (Gene Expression Wash Buffer; cat. no. 5188-5325 and 5188-5326; all Agilent Technologies, Inc.) were performed based on the manufacturer's standard protocols. Total RNA was transcribed to double-stranded cDNA, then synthesized into cRNA and labeled with Cyanine-3-CTP. Labeled cRNAs were subsequently hybridized onto the 8x60 K Agilent Rat long non-coding RNA (lncRNA) Array. Following washing, the arrays were scanned using the Agilent Scanner G2505C (Agilent Technologies, Inc.). Feature Extraction software (v.10.7.1.1; Agilent Technologies, Inc.) was used to analyze array images to obtain raw data. Genespring software (v.13.1; Agilent Technologies, Inc.) was utilized to conclude basic analysis using raw data.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
