Phage are streaked onto a medium to obtain an independent isolate prior to preparing a new lysate. This is done to reduce the likelihood of working with lysates which have become contaminated, and/or have accumulated mutations. - [Read Streaking Lambda Phages Protocol]
Protocol describes the preparation of subtracted cDNA probes by hybridization to an mRNA driver, followed by purification of the single-stranded radiolabeled cDNA by hydroxyapatite chromatography. Before preparing the probe, it is a good idea to have filters (which contain the cDNA library to be screened) ready to hybridize. - [Read Synthesis of Radiolabeled, Subtracted cDNA Probes Using Oligo(dT) as a Primer Protocol]
The following procedure is for simultaneous transfection and plating of RAW 264.7 cells. This protocol results in approximately 50% to 70% cell viability, and of those viable cells, 20% to 40% are transfected when using pEYFP-N1
from Clontech. Include: Procedure for Splitting Cells before Transfection; Procedure for Preparing Lipofectamine 2000 and DNA; Preparation of RAW 264.7 Cells for Transfection. - [Read Transfecting and Plating RAW 264.7 Cells with Lipofectamine 2000 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.
