Each fourplex microarray slide included the control strain, E. faecalis V583 to monitor the correlation between the hybridizations and to produce an appropriate cut off value.
The control spots of non-human origin in cDNA microarray slide include the U2 RNA gene, Hepatitis C Virus coat protein gene and spotting solution alone without DNA.
Data processing of the scanned microarray slide included signal intensity measurement with the ImaGene software program, followed by median pin-tip (c.q. sub array) normalization.
Microarray chips of the size of histology slides including all known human genes are currently manufactured with high precision.
Slides included internal controls to ensure staining reproducibility between slides.
Therefore, the microarray slides comprised 45,220 features including 1417 Agilent internal controls and 800 internal controls that represented 80 randomly chosen A. nidulans ORFs (each 10-times replicated).
Methods: Immunohistochemical analysis of EMMPRIN and EGFR was performed in tissue microarray slides of 90 surgical specimens including 32 well differentiated, 35 moderately differentiated, and 23 poorly differentiated colorectal adenocarcinomas.
This particular miRNA was not included on microarray slides in the other studies.
A total of 115 endometrial cancer specimens and five normal endometrial specimens were included on the microarray slides.
This staining protocol has been validated by comparing it with the HercepTest™ kit (DAKO, Cat# K5204) using commercial tissue microarray (TMA) slides, which included tissue slides from 70 breast cancer cases (BR701, US Biomax Inc).
