Cattle and buffalo were infected with cercariae by back patch.Before infection and after infection with 49d ,we collected peripheral blood from tha animals, and treated with TRIZOL Reagent as quickly as possible.
Growth protocol
Peripheral blood were collected from the jugular vein of cattle,buffalo,1-2 year old,healthy,were kept in non-infected areas.And cercariae were provided by Jiangsu Institute of Schistosomiasis Control
Extracted molecule
total RNA
Extraction protocol
Total RNA was extracted using TRIZOL Reagent (Cat#15596-018，Life technologies, Carlsbad, CA, US)following the manufacturer’s instructions and checked for a RIN number to inspect RNA integration by an Agilent Bioanalyzer 2100 (Agilent technologies, Santa Clara, CA, US).Qualified total RNA was further purified by RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany) and RNase-Free DNase Set (Cat#79254, QIAGEN, GmBH, Germany).
Label
Cy3
Label protocol
Total RNA was amplified and labeled by Low Input Quick Amp Labeling Kit, One-Color (Cat#5190-2305, Agilent technologies, Santa Clara, CA, US), followed the manufacturer’s instructions. Labeled cRNA were purified by RNeasy mini kit (Cat#74106, QIAGEN, GmBH, Germany).
Hybridization protocol
Each Slide was hybridized with 1.65μg 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.
Description
Gene expression profile of peripheral blood from cattle before infected with scistosoma japonicum, replicate3
Data processing
The scanned images were analyzed with Feature Extraction software (Agilent technologies, Santa Clara, CA, US)with default settings.
