Protocol for the extraction of calf brain lipids. Protocol describes a rapid method to isolate lipids from bovine brain tissue using an organic solvent mixture of Chloroform and Methanol. - [Read Extraction of Calf Brain Lipids Protocol]
Organic solvents such as alcohols and acetone remove lipids and dehydrate cells, precipitating the proteins on the cellular architecture. Be aware that different antigens may be affected differently by the various solvents. If no previous data are available for your antigen, start with the 50/50 mixture. For tissue culture dishes, concentrations of acetone higher than 50% will destroy the integrity of the plastic. - [Read Fixing Attached Cells in Organic Solvents Protocol]
In brief, the reaction mixture, is prepared in exactly the same way as if the sample is to be stained or shadowed for electron microscopy, but once the... Gold labeling technique for electron microscopic identification and location of proteins. - [Read Gold labeling of proteins for electron microscopy]
Protocol outlines the general procedure and requirements for in vitro translation of CFTR and outlines some assays using in vitro translated product. Core glycosylation of CFTR occurs in the ER. An assay for this processing step requires the
addition of microsomal membranes to the basic in vitro translation mixture. This protocol takes this into account. - [Read In vitro Translation Assays for CFTR]
A flow cytometry technique is presented, which results in the selection and isolation of two populations of cells from a complex mixture based on physical properties (e.g., size and internal granularity) and correlated expression of several surface molecules - [Read Isolation of Ly-1+/CD5+ B Cells by Cell Sorting Protocol]
Early embryos (0-17 hours or until cuticle formation) are treated with a mixture of organic solvents, formaldehyde, and alcohols, as described here. The cuticles of late-stage embryos are usually opened by sonication. Tissues from more advanced stages of development are normally dissected by hand and then fixed and stained in a standard paraformaldehyde/detergent combination - [Read Preparing Early Whole-Mount Drosophila Embryos for Immunostaining Protocol]
Early and late embryos are treated with a mixture of organic solvents, formaldehyde, and alcohols. The cuticles of late-stage embryos (17-22 hours or until hatching) are usually opened by sonication, as described here. Tissues from later stages of development are normally dissected by hand and then fixed and stained in a standard paraformaldehyde/detergent combination. - [Read Preparing Late Whole-Mount Drosophila Embryos for Immunostaining Protocol]
This protocol is employed for the purification of a population of muscle-derived cells from skeletal muscle of C57Bl/6 animals. The resulting preparation is a mixture of many cell types including satellite cells (a.k.a., muscle progenitor cells) and hematopoietically active muscle-derived cells. - [Read Protocol for the Isolation of a Heterogenous Muscle-Derived Cell Population]
PCR is used as a preparative tool for the synthesis of a high-complexity double-stranded DNA library. In the example presented here, a mixture of synthetic oligonucleotides is used to synthesize a random peptide NNK library, where K is either T or G. The exclusion of A and C nucleotides at the third position decreases the occurrence of stop codons but still allows codons for all 20 amino acids. - [Read Use of PCR to Prepare a Double-Stranded DNA Library Encoding Random Peptides Protocol]
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.
3' Rapid Amplification of cDNA Ends RACE Using PCR Protocol. This protocol contains the steps for 3' end rapid amplification of mRNA by PCR. The first-strand cDNA is synthesized from total or poly(A+) RNA by priming from the poly-A tail of the mRNA using a oligo (dT) adaptor primer. The cDNA is then amplified via PCR using a gene-specific primer and an adaptor primer.
