The Objective
SBM-DB aims to investigate mainly Human disease and other mammalian's. Analysis from comprehensive gene expression profiles may help to define out the causes of disease in molecular level.

Experimental Procedure
Experimental procedures for GeneChip were performed according to the Affymetrix GeneChip Expression Analysis Technical Manual. Briefly, each 10 mg RNA are used to synthesize biotin-labeled cRNA, which was then hybridized to the high-density oligonucleotide array (GeneChip Human U133 array; Affymetrix, Santa Crara, CA). After washing, arrays were stained with streptavidin-phycoerythrin and analyzed by a Hewlett-Packard Scanner to collect image data.

Data Analysis
GeneChip Analysis Suite software version 5.0 was used to calculate the Signal value, and Detection Call (called "Average Difference", "Absolute Call" in previous MAS4.0).

Probe Information
Each Probeset have a GenBank Accession number, and we mapped with UniGene ClusterID. (Human Unigene Build #148, 1 April, 2002)
