This protocol decribes derivation of TS cell lines from 3.5-days post coitum (dpc) mouse blastocysts. The procedure is similar to the derivation of embryonic stem (ES) cell lines. However, the success rate is considerably higher, and less expertise is required to recognize pluripotent TS cell colonies. - [Read Derivation of Trophoblast Stem (TS) Cell Lines from Blastocysts Protocol]
Three Ambion kits were used to quantitate specific miRNAs and to detect differential miRNA expression in various mouse brain regions and cell types isolated by laser capture microdissection (LCM). These techniques can be applied to studying miRNA in other species, tissues, and cell types. Includes: Obtain Laser Capture Microdissected Samples; Isolate miRNA from LCM Samples; Quantitate miRNA by qRT-PCR. - [Read Detect and Quantitate MicroRNA in Laser Capture Microdissection Samples]

Protocol for Detection (FISH). TRITC, or Avidin Cy-5. For the probes labeled with digoxigenin, we usually first incubate with mouse-anti-digoxigenin, followed by incubation with sheep anti-mouse Cy5.5, or other fluorochrome conjugated antibodies. - [Read Detection FISH Protocol]
In vitro differentiation of ES cells occurs when the cells are allowed to aggregate in suspension culture in the absence of mouse embryonic fibroblast (MEF) feeders and leukemia inhibitory factor (LIF). Hanging drops provide a uniform aggregate size, which is then expanded by continued growth in suspension culture. The embryoid bodies are then plated and allowed to differentiate further in culture. - [Read Differentiation of Embryonic Stem (ES) Cells Using the Hanging Drop Method]
Direct sequencing from amplified bacterial and large insert cloned human or mouse genomic DNA via an improved MultiPlex PCR-based method. Includes: Preparing primers for MP-PCR; Amplification; PCR Product Clean-up; Sequencing. - [Read Direct Sequencing Using MultiPlex PCR-Based Method]
Protocol describes a method for electroporating DNA into ES cells, as well as selection methods. Pilot studies should be performed to optimize the conditions for each DNA construct. The selection method described here is one of the most complex. It involves targeting constructs in which the bacterial neomycin-resistance gene disrupts the coding sequence of the mouse gene. - [Read Electroporating DNA into Embryonic Stem (ES) Cells and Selection Methods Protocol]
Mice fed with the cytohesin inhibitor SecinH3 for two days develop hepatic insulin resistance that can be identified by reduced liver glycogen levels, increased serum insulin and ketone body levels and decreased serum non-esterified fatty acid. To confirm the presence and identity of SecinH3 in mouse liver, we extracted the compound from liver homogenates with chloroform and identified it by LC/MS. - [Read Extraction of the SecinH3 from Mouse Liver Protocol]
Protocol describes the purification of mouse T cells, B cells, and T cell subsets using magnetic bead separation. Isolation of cell subsets using magnetic beads is quick, simple, and reliable and can result in high yields of very pure cells. - [Read Fractionation of T and B Cells Using Magnetic Beads 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.
