Protocol describes a safe and convenient method of extracting DNA from Coccidioides immitis fungi in which the culture is killed by steaming, allowing removal from the containment facilities, as soon as possible. The method was first developed with the non-pathogen Neurospora crassa, has worked well for both C. immitis and H. capsulatum, and should be useful for extracting DNA from any pathogenic fungus. - [Read A Safe Method of Extracting DNA from Coccidioides immitis Protocol]
Cajal Body Isolation Protocol. Protocol includes: Sonication, Removal Nucleoi, Gradient One, Gradient two, Concentration and final enrichment of cajal bodies. Also includes: Making 2.55M sucrose stock and Analysis of the enriched Cajal body fraction. - [Read Cajal Body Isolation Protocol]
Protocol describes the application of peroxidase or alkaline phosphatase conjugates in the immunohistochemical labeling of formalin-fixed, paraffin-embedded tissue sections. Includes: Removal of Paraffin and Rehydration; Antigen Retrieval - Unmasking of Antigen; Enzyme retrieval; Microwave retrieval; Inactivation of Endogenous Peroxidase; etc.. - [Read Immunohistochemistry Protocol]
Protocol was developed to isolate Wolbachia from adult Drosophila, but it can be adapted for other insects. In some insects leg removal prior to isolation facilitates hemolymph extrusion. - [Read Isolation of Live Bacteria from Adult Insects Protocol]
Protocol describes how to remove the gonads, determine the sex ofmouse embryos 13.5 days post coitum and visualize the germ cells, through use of an alkaline phosphatase staining. - [Read Mouse Gonad Removal and Germ Cell Staining Protocol]
Protocol describes a method for removal of mouse ovaries in combination with the administration of progesterone, which causes the arrest of blastocyst development. This procedure is performed during the afternoon of the third day of pregnancy to ensure that the morulae have moved sufficiently into the oviducts and will be less likely to be damaged during the ovariectomy. - [Read Ovariectomy for Induction of Blastocyst Implantation Delay Protocol]
Details a placenta specific gene manipulation by transducing blastocysts with lentiviral vectors1. After a removal of zona pellucida which functions as a physical barrier, trophoblast cells lying outermost layer of blastocyst were transduced from outside with high-titer lentiviral vectors. As most placental cells descend from trophoblast cells while fetus originated from inner cell mass, transgene expression can be observed in trophoblast cells from preimplantation stages and in placenta... - [Read Placenta Specific Gene Manipulation by Transducing Zona-Free Blastocyst using Lentiviral Vector]
Protocol for the production of completely ES cell-derived fetuses by aggregation with tetraploid embryos. Includes: Recovery of 2-cell stage embryos; Production of tetraploid embryos; Preparation of aggregation plate; Removal of Zona Pellucida; ES cells/ tetraploid embryo "SANDWICH" aggregation;
Transfer of embryos. - [Read Production of Completely ES Cell-Derived Fetuses by Aggregation with Tetraploid Embryos]
Laboratory sample cleanup is a necessary part for analytical preparation analysis. The removal of Contaminants such as proteins, cell debris and other materials is an important step. Typically this has been done by using Acetonitrile and then Centrifugation to pellet the debris leaving the clean supernant. After this process supernatant can be used for further analysis by HPLC, GC, MS and other analysis tandem methods. HTS Labs. - [Read Protein Precipitation Microplate]
Removal of CCR5 ligands and induction of pro-resolving lipid mediators by apoptotic neutrophils during resolution. Application of lipid extraction from peritoneal exudates, in tandem with lipid mediator informatics can be used to determine the role of apoptotic neutrophils in the generation of resolution phase lipid mediators. This neutrophil transfer system allows the determination of the direct impact of apoptotic leukocytes in the resolution of inflammation. - [Read Removal of CCR5 Ligands and Induction of Pro-Resolving Lipid Mediators by Apoptotic Neutrophils]
Protocol is the second in a set of three, describing fluorescent mRNA differential display (FDD or FDDRT-PCR). For the purposes of FDD gene expression analysis, as well as any other RNA-based gene expression technologies, contaminating genomic DNA must be removed before reverse transcription and subsequent PCR. - [Read Removal of Genomic DNA from Total RNA for Use in Fluorescent mRNA Differential Display Protocol]
This method is advantageous for saving the occasional cultures that become contaminated. Yeast contaminated cultures will appear cloudy when slightly shaken and lymphocytes will not cluster together as much as normal. If cultures are suspect, a drop of culture can be streaked on a YPD media plate to check for growth of yeast colonies, or a 5 ml sample can be taken to Barnes Diagnostic Center for identification of yeast strain. - [Read Removal of Yeast Contamination from Lymphoblast Cultures Protocol]
Protocol describes a simple method for removal of the zona pellucida of preimplantation mouse embryos using an acidified Tyrode’s solution. - [Read Removal of Zona Pellucida Protocol]
The protocol gives general considerations for the design of targeting vectors for transgenic mice. The protocol shares tips in the design of knock-out and knock-in vectors and some of their strategies for producing homologously recombined embryonic stem cells.
