This sample preparation method is a direct replacement for the dried droplet technique. It produces more uniform samples than the dried-droplet technique and the crystals are better adhered to the sample stage’s surface. MALDI Sample preparation. PROWL - [Read Seeded films (Vorm-Roepstorff) MALDI Protocol]
Protocol for slide preparation for cytogenetics. Includes: Improved cell recovery by microcentrifugation; Slide storage; "Controlled" chromosome spreading; Dropping cells from a height does not improve spreading; GTG-banding. - [Read Slide Preparation for Cytogenetics Protocol]
Slide Preparation for Manual Microdissection for Subsequent DNA, RNA, and Protein Analysis. Manual microdissection and subsequent molecular analysis can be carried out on slides stained using standard hematoxylin and eosin methods. However, if cell types that are (or are not) expressing a specific protein are required for a study, then more advanced slide preparation methods such as Immuno-LCM may be utilized. - [Read Slide Preparation for Manual Microdissection Protocol]

Protocol for spore germination. This procedure is typically used for the isolation and preparation of spores from a diploid strain heterozygous for a marked disruption (e.g., yfg1::his3+) Inoculation of the spore population into minimal medium lacking the nutritional supplement corresponding to the disruption marker (e.g., minimal medium lacking histidine) allows only the disruption spores to germinate. - [Read Spore Germination 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]

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.
In Vitro Translated Xenopus Mos Kinase Assay Protocol. In response to progesterone, immature Xenopus oocytes mature to eggs that can be fertilized. The Mos protein kinase is essential for oocyte maturation, most likely due to its ability to activate the MAP kinase cascade. This MAP kinase cascade eventually leads to the activation of Cdc2/cyclin B and entry into M phase. In this protocol, tagged Mos kinase is translated in vitro, immunopurified, and used in a kinase assay.
A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.
