This cDNA synthesis system simplifies your work dramatically. All reaction components are premixed and lyophylised. You have to add your RNA and (for Your-Prime beads) the primer. Another advantage of the system is a little number of pipetting steps required, and therefore reduced risk of Rnase contamination and RNA degradation. - [Read First strand cDNA synthesis with Ready-To-Go Beads Protocol]
After fixation, frozen sections are immunostained under RNase-free conditions using a rapid three-step streptavidin-biotin technique followed by dehydration. The immunostained sections are ready for LCM. Includes: Development of Immuno-LCM. - [Read Immuno-Laser Capture Microdissection Protocol]
In this protocol, bacterial cells are lysed by being subjected to short, intense treatments with ultrasound, which breaks the cell walls and shears the DNA into sizes that will not affect the viscosity of the samples. Note that this method causes some denaturation of the samples. The resulting lysate is ready for preclearing. - [Read Immunoprecipitation: Lysing Bacteria by Sonication Protocol]
Purified Tubulin is polymerized and then stabilized with Taxol. The resulting Microtubules are then ready for use in motility assays. Protocol use solutions such as 50 mM Mg-GTP, 50 μl 100 mM GTP, 40 μM Taxol, Taxol Stock,and PM Buffer. - [Read Protocol for Microtubule Assembly]
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]
Protocol describes a method for vasectomy in which the vas deferens is accessed through the abdominal wall. Mice are ready for mating after ~10-14 days. Vasectomized males can be bred with fertile females to obtain plugs for timed matings. The pseudopregnant females can then be used for oviduct and uterine transfers. For an alternative protocol, see Vasectomy for Generation of Sterile Males: Access via Scrotal Sac. - [Read Vasectomy for Generation of Sterile Males: Access via Abdominal Wall Protocol]
Protocol describes a method for vasectomy in which the vas deferens is accessed through the scrotal sac. Mice are ready for mating after ~10-14 days. Vasectomized males can be bred with fertile females to obtain plugs for timed matings. The pseudopregnant females can then be used for oviduct and uterine transfers. - [Read Vasectomy for Generation of Sterile Mouse Males: Access via Scrotal Sac Protocols]
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.
This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.
