Category: Primary Cell Isolation and Culture Protocols: Laser Capture Microdissection Protocols: Tissue Preparation for LCM Protocols

LCM isolates specific cells or tissues from samples mounted on microscope slides. The samples are viewed through a thermoplastic film that is attached to a microcentrifuge tube lid. Localized heat, caused by the application of a laser pulse, fuses the membrane to the cells of interest, which can then be harvested for further analysis. RNA and proteins can be purified from the isolated cells, allowing detailed analysis of gene expression. This protocol is divided into three stages. - [Read (LCM): Preparation and Sectioning of Frozen Tissue Blocks and Purification of RNA from Isolated Cel]

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols: Peroxisome Isolation Protocols

Peroxisomes of higher eukaryotes, glycosomes of kinetoplastids, & glyoxysomes of plants are related microbody organelles that perform differing metabolic functions tailored to their cellular environments. The close evolutionary relationship of these organelles is most clearly evidenced by the conservation of proteins involved in matrix protein import and biogenesis. glycosome can be viewed as an offshoot of the peroxisomal lineage with additional metabolic functions, specifically glycolysi - [Read Biogenesis and Function of Peroxisomes and Glycosomes]

Category: Transfection Protocols

Protocol should be viewed as a starting point for systematic optimization of transfection mediated by lipofecting agents. Once a positive signal has been obtained from a transfected plasmid carrying a standard reporter gene, optimal conditions for transfection can be established by systematic variation of parameters such as the initial cell density, the amount and purity of DNA, the media and serum, and the time of exposure of the cells to the cationic-lipid-DNA complex. - [Read DNA Transfection Mediated by Lipofection Protocol]

Category: Cell Biology and Cell Culture: Apoptosis Protocols: Apoptosis Analysis

Leukostat Staining of Cytospin Preparations to Detect Apoptosis. Shailaja Kasibhatla et al. Leukostat staining is used to visualize nuclear changes and apoptotic body formation that are characteristic of apoptosis. Cells are viewed under a light microscope and counted to quantify apoptosis. This protocol can be used both for cells that grow in suspension and for adherent cells. - [Read Leukostat Staining of Cytospin Preparations to Detect Apoptosis]
