Gene Expression Array Service 4*44K
Gene Expression Array Service 8*60K

Gene expression profiling is a technology that utilizes microarrays to analyze genome-wide profiling of gene expression. Arraystar's gene expression profiling service is based on the most powerful platform in this field, Agilent. The availability of the array services from the platform offers our customers variety of choices in array content, density and analysis tools. The gene expression arrays that are most often selected by our customers include:

Agilent Whole Genome Expression Arrays

Microarray Species Format Probe length Coverage Probes /target gene
Whole Human Genome Human 4 * 44K 60-mer 27,958 1
Whole Mouse Genome Mouse 4 * 44K 60-mer 39,430 1
Whole Rat Genome Rat 4 * 44K 60-mer 26,930 1

• RNA isolation (Optional)


• cDNA synthesis

• Target preparation by labeling with Cy3

• Array hybridization, washing, and scanning

• Data extraction, analysis and summarization

Arraystar's bioinformatics team has extensive experience in analyzing gene expression array data. We provide two levels of analysis: standard and advanced.

Standard Data Analysis

• Raw Data Files

• Summary Report

• Box Plot, Scatter Plot and Hierarchical Clustering

• Differentially Expressed Gene Screening

• GO Analysis (Fig.1) and Pathway Analysis

Fig.1 GO Analysis (Standard Data Analysis).  Significant GO terms of differentially expressed gene. A bar plot is generated from the top 10 GO terms containing the largest fold enrichment of differentially expressed genes. The plot gives a more intuitive view of the significant GO terms.
