Cellular biology F low cytometry protocols

Apoptotic cells are cleared in vivo by the process of phagocytosis, in which specific “phagocytes” move to the site of apoptosis, engulf the dying cells and digest them. Apoptosis has a central role in many physiological processes, for example, in the immune system. Autoreactive cells are deleted via apoptosis to prevent autoimmunity. Cell Death & Differentiation – Apoptosis Methods and Flow Cytometry ProtocolsThis book, the product of a number of contributing authors, aims to describe the basic methods for studying apoptosis. Each method is Cutting-edge and highly practical, Apoptosis Techniques and Protocols, Second Edition, offers both novice and seasoned investigators a rich panoply of the productive tools they need to unravel the molecular mechanisms of neuronal cell death.

The use of the annexin V apoptosis assay protocol is a common method for detecting apoptotic cells. The below protocols are recommended for use with the specific flow cytometry kits mentioned. Please see the Annexin V Staining page for a discussion about general experimental conditions and avoiding false positives, or to review a selection guide for all of our annexin V Detailed protocol for inducing apoptosis using camptothecin. Alternative reagents for inducing apoptosis are also noted.

Apoptosis protocol and methodsSummary: Cell death can occur by either of two distinct mechanisms, necrosis or programmed cell death (apoptosis). Necrosis is a pathological process which occurs when cells are exposed to a serious physical or chemical insult. Apoptosis is a physiological and controlled process by which unwanted or useless cells are eliminated during PI is excited by wavelengths between 400 and 600 nm and emits light between 600 and 700 nm, and is therefore compatible with lasers and photodetectors commonly available in flow cytometers. This protocol for PI staining can be used to quantitate cell death in most modern research facilities and universities. Cutting-edge and comprehensive, Flow Cytometry Protocols, Fourth Edition researchers and scientists who are interested in continuing or expanding their knowledge of flow cytometry.

This protocol provides detailed procedures for using flow cytometry to assess key cellular events such as membrane integrity, cell cycle progression, and apoptosis in cells exposed to treatments. Flow cytometry allows for the simultaneous analysis of multiple cell Staining protocols may also need to be optimized. Long incubation times may alter the apoptosis levels and intracellular staining requires fixation and permeabilization of cells. Table 1. Flow cytometry validated antibodies against receptors of the extrinsic apoptosis pathway.

Protocol for Apoptosis Assay by Flow Cytometry Using Annexin V Staining Method Imayavaramban Lakshmanan and Surinder K Batra* Biochemistry and Molecular Biology, Nebraska Medical Center, Omaha, USA *For correspondence: [email protected] [Abstract] This assay is used to count the number of cells that have undergone apoptosis. On method is Cutting edge apoptosis or necroptosis the TMRM signal is lost. The advantage of using Annexin V FITC /DAPI/TMRM is that the entire cell population is labeled, and it is easy to distinguish living (TMRM + /Annexin V FITC -/DAPI-) from dying or dead cells (apoptosis: TMRM-/Annexin V FITC + /DAPI-; necrosis: TMRM-/Annexin V FITC + /DAPI+).

Discriminating Between Apoptosis, Necrosis

Flow Cytometry of Apoptosis This unit describes the most common methods applicable to flow cytometry that make it possible to: (1) identify and quantify dead or dying cells, (2) reveal a mode of cell death (apoptosis or necrosis), and (3) study mechanisms involved in cell death. Gross changes in cell morphology and chromatin condensation, which occur during apoptosis, can be

This chapter of the Protocols and Applications Guide explains the molecular mechanisms of apoptosis, how to confirm apoptosis, and the use of multiplexed assays using a single sample. Abstract Immunohistochemistry is commonly used to show the presence of apoptotic cells in situ. In this protocol, B-cell lymphoma cells are injected into recipient mice and, on tumor formation, the mice are treated with the apoptosis inducer vorinostat (a histone deacetylase inhibitor). Tumor samples are fixed and sectioned, and fragmented DNA (a feature of apoptotic cells) is end

Death Staurosporine Induction of Apoptosis by Treatment with Staurosporine Staurosporine ( Streptomyces staurospores) is a relatively non-selective protein kinase inhibitor, which blocks many kinases to different degrees. Staurosporine is often used as a general method for inducing apoptosis 1.

Proteases in apoptosis have evolved as major drug targets in the past few decades. Development in this direction has been brought about by efficient design and refinement of the various platforms of protease assays. These can be broadly categorized into general The serious physical caspases involved in specific apoptosis scenarios can be identified using substrate-based inhibitor studies (see Protocol: Assaying Caspase Activity In Vitro and Protocol: Identification of Active Caspases Using Affinity-Based Probes [McStay and Green 2014d, e]).

This assay is used to count the number of cells that have undergone apoptosis. Apoptosis will be detected by initially staining the cells with Annexin V and propidium Iodide solution followed by flow cytometry analysis. It is based on the principle that normal cells are hydrophobic in nature as they Introduction Single-cell suspensions are required for all flow cytometry assays. Thus, peripheral blood cells or cells that grow in suspension are well suited for analysis by flow cytometry. Adherent cell lines, solid tissue samples, and tumors require processing into single-cell suspensions before they can be analyzed. Numerous protocols are available and may involve
