Immuno-labelling

Using metaphase spreads from human lymphoblastoid cell lines, we previously showed how immunofluorescence microscopy could define the distribution of histone modifications across metaphase chromosomes. We showed that different histone modifications gave consistent and clearly defined immunofluorescent banding patterns.

Efforts to elucidate the cellular and molecular mechanisms of regeneration have required the application of methods to detect specific cell types and tissues in a growing cohort of experimental animal models. For example, in the planarian Schmidtea mediterranea, substantial improvements to nucleic acid hybridization and electron microscopy protocols have facilitated the visualization of regenerative events at the cellular level.

Protein function in eukaryotic cells is often controlled in a cell cycle-dependent manner. Therefore, the correct assignment of cellular phenotypes to cell cycle phases is a crucial task in cell biology research. Nuclear proteins whose localization varies during the cell cycle are valuable and frequently used markers of cell cycle progression.

Breast cancer is one of the leading causes of cancer deaths. Triple-negative breast cancer (TNBC), an immunophenotype defined by the absence of immunolabeling for estrogen receptor (ER), progesterone receptor (PR) and HER2 protein, has a highly aggressive behavior.

In conclusion, the results reported herewith show a significant relationship between epifluorescence microscopy and flow cytometry, but coefficients of variation were considerably lower for bacterial counts estimated by flow cytometry than epifluorescence microscopy. Generally, the use of flow cytometry in marine microbiology reduces the processing time of the sample and increases the number of processed samples.

Neuronal cell-surface antigens can be the target of antibodies in some patients with paraneoplastic encephalitis. A few of these antigens have been identified, including the NR1/NR2 subunits of NMDA receptors (Fig. 97-1) and voltage-gated potassium channels (VGKC). These disorders are more responsive to immunotherapy than those associated with immune responses to intracellular antigens. Figure 97-1 Antibodies to NR1/NR2 subunits of the NMDA receptor in a patient with paraneoplastic encephalitis and ovarian teratoma.
