This CGH Protocol is used for DNA of good quality when available in sufficient amounts. We usually do replicate hybridizations using samples labeled "inversely" (reversing the label for test and normal DNA's). If appreciable artifact occurs, then alternative labels are tried. - [Read CGH of Direct Labeled Test DNA vs Normal DNA Protocol]
Manual measurement and manipulation of the cell surface requires access to the cells, usually in an open chamber. Temperature-controlled chambers or stage inserts are preferred for maintaining physiological activity during the experiment. For example, heated culture dishes with coverslip glass bottoms (Bioptechs) permit high-resolution fluorescence microscopy of living cells during force application. - [Read Chambers for Examination of Live Cells under Mechanical Stress Protocol]

Protocol uses specific antibodies coupled to one of four fluorochromes: fluorescein isothiocyanate (FITC), R-phycoerythrin (PE), peridinin chlorophyll-a (PcP),
and allophycocyanin (APC). These fluorochromes can be used simultaneously to stain and analyze the expression patterns of four different proteins in the same sample. The
fluorochrome stained cell populations are analyzed using a FACSCalibur dual-laser flow cytometer. - [Read Characterization of Cells by Flow Cytometry Protocol]

Immobilized metal ion affinity chromatography (IMAC) exploits a molecule’s affinity for chelated metal ions. The amino acid histidine present in many proteins forms complexes with transition metal ions such as Cu2+, Zn2+, Ni2+ and Fe3+. Chelating Sepharose™ Fast Flow with a suitable immobilized metal ion will therefore selectively retain proteins with exposed histidine. - [Read Chelating Sepharose Fast Flow Protocol]
This protocol describes how to use DIG Chem-Link to directly label any DNA [e.g. plasmids, PCR products, cDNA prepared
from mRNA] or RNA (e.g. total RNA, poly(A)+ mMRNA). The
DIG Chem-Link or Biotin Chem-Link may also be used to label oligonucleotides. Includes: Required Purity of DIG Chem-Link Templates; Direct DIG Labeling of mRNA or cDNA with DIG Chem-Link; Key Product Required for Direct Labeling of DNA or RNA; Estimating the Yield of DIG-labeled Nucleic Acids. - [Read Chem-Link Labeling of DNA or RNA with DIG or Biotin Protocol]
A Single Stranded Plasmid DNA Isolation Protocol describing the production and isolation of single-stranded DNA (ssDNA) using bacteriophagemid-containing bacteria and helper phage. Infection of the host cells with helper phage allows for packaging of ssDNA into bacteriophage. The ssDNA can then be isolated from phage particles.
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.
Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.
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.
