Assay of cytokines in tissue culture supernatants describes a liquid suspension array for quantification of cytokines in tissue culture supernatants or serum. With this assay, it is possible to profile the level of multiple cytokines in a single well. The principle of this cytokine assay is similar to a capture sandwich immunoassay. Includes: Preparation for the Assay, Cytokine Assay, Reagents and Materials. - [Read Assay of Cytokines in Tissue Culture Supernatants]

This protocol describes the first step in constructing an array: amplification of the predicted ORFs that are to be included in the array. Gene-specific primers containing vector-specific flanking sequences that facilitate recombinational cloning are used to amplify each ORF. A secondary amplification can be used to extend the length of the homologous vector sequence flanking the ORF. - [Read Genome-Wide Analysis of Protein-Protein Interactions Using a Two-Hybrid Array: Amplification of ORFs]
Protocol details the preparation of biotin-labeled target samples and hybridization of these samples to an Affymetrix in situ synthesized oligonucleotide GeneChip array. The procedure requires a minimum of 5 µg of purified total RNA as starting material. - [Read Microarray Protocol for Affymetrix In Situ Synthesized Oligo Arrays]
Protocol details the preparation of fluorescently labeled target samples and hybridization of these samples to a microarray of Agilent inkjet-deposited presynthesized oligonucleotides. The procedure requires a minimum of 3 µg of purified total RNA as starting material. - [Read Microarray Protocol for Agilent Inkjet-Deposited Presynthesized Oligo Array]
Protocol describes how to test whether a transcription factor disrupts the chromatin of a promoter of a gene of interest. First, chromatin is assembled in vitro on the gene of interest in the presence and absence of a transcriptional activator (see Protocol on Assembly of Chromatin with Drosophila S-190 Chromatin Assembly Extract and Transcriptional Activators). - [Read Nucleosomal Array Disruption Assay Protocol]

DNA microarrays are an ordered arrangement of DNA molecules complementary to genes of interest that are "spotted" by robotic equipment onto a glass slide substrate. The expression of genes in cells can be monitored with microarrays by preparing cDNA from the mRNA of cells of interest and measuring the hybridization to the microarray. This protocol describes the labeling of genomic DNA for use as a probe for hybridization to the cDNA spotted on the array.
This Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA protocol describes the production of probes labeled with the fluorescent dyes, Cy3 and Cy5, following the synthesis of cDNA from human mRNA and the hybridization of the probes to DNA microarrays.
