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]
Protocol for double immunofluorescence staining for BCL-6. Any type of tissue is suitable for this technique, as long as the antigenicity for your antigen(s) is preserved. Includes: unfixed or acetone-fixed specimens; dewaxed, antigen retrieved slides. - [Read Double Immunofluorescence Staining for BCL-6 Protocol]
Glass is an excellent substrate for most tissue-culture-adapted cells and is compatible with all fixing and staining solutions. Glass coverslips in tissue-culture dishes or in 24-well multiwell plates are suitable carriers, as are multiwell slides. For high-resolution studies, choose glass coverslips of the highest available grade; #1 or #1.5 coverslips are the appropriate thickness. - [Read Growing Adherent Cells on Coverslips or Multiwell Slides 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]
Indirect method measuring immunofluorescence coupled to second antibody. Best for membrane antigens in addition to intra- and extracellular antigens, may be applied to frozen tissue sections, to cells in suspension, and to cells attached to glass slides or coverslips.

Protocol for immunohistochemistry with AP-Conjugated (NBT/BCIP). Protocol extensively blocks slides, further diluting the primary antibody, lengthening the incubation and washing time, using a simple AP-conjugated secondary at high dilution and use a slow long development with the most powerful IHC development, NBT/BCIP. Includes: Single AP stainiing and Double AP staining. - [Read Immunohistochemistry with AP-Conjugated (NBT/BCIP) Protocol]
Protocol for In situ hybridization to human metaphase chromosomes using DIG-, biotin-, or fluorochrome-labeled DNA probes and detection with fluorochrome conjugates. Includes: Pretreatment of metaphase spreads on slides; Denaturation and hybridization; Single color fluorescent detection with immunological amplification; Multicolor fluorescence in situ hybridization (Multicolor FISH); Results obtained with human metaphase chromosome spreads. - [Read In Situ Hybridization to Human Metaphase Chromosomes using DIG-, Biotin- or Fluorochrome-Labeled DNA]
Protocol for indirect peroxidase technique. Includes: Sections: Thickness-Between 5 and 10 microns. Pick up on chromic acid etched, poly-L-lysine or chrome alum/gelatine coated slides. Dry at room temperature overnight (not longer than 72 hours). - [Read Indirect Peroxidase Technique Protocol]
