A detailed protocol for bisulfite treatment of DNA. DNA is first digested with a restriction enzyme. DNA is denauted at 97C for 5min. Bisulfite protocol is included. Also DNA purification using the Promega Wizard DNA Cleanup kit in indicated. Fan Lab. UCL - [Read Fan Lab Bisulfite Treatment of Genomic DNA]
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. Includes: cDNA Synthesis; Fluorescent cRNA Synthesis; cRNA Precipitation and Cleanup; cRNA Quantification; Hybridization; Washing. - [Read Microarray Protocol for Agilent Inkjet-Deposited Presynthesized Oligo Arrays]
Laboratory sample cleanup is a necessary part for analytical preparation analysis. The removal of Contaminants such as proteins, cell debris and other materials is an important step. Typically this has been done by using Acetonitrile and then Centrifugation to pellet the debris leaving the clean supernant. After this process supernatant can be used for further analysis by HPLC, GC, MS and other analysis tandem methods. HTS Labs. - [Read Protein Precipitation Microplate]
Protocol details the preparation of fluorescently labeled target samples and hybridization of these samples to a microarray of Agilent inkjet-deposited cDNAs. The procedure requires a minimum of 5 mg of purified total RNA as starting material. Includes: First Strand cDNA Synthesis; Second Strand cDNA Synthesis; cDNA Cleanup and Precipitation; In vitro Transcription; Cleanup and Quantification of in vitro Transcribed RNA; Fluorescent Labeling of the Target Samples. - [Read Transcript Profiling by Microarray Analysis Protocol.]
