Detection of programmed electric mobile phone decease of HT1080 Cells by Fluorescence spark off Cell Scanning Introduction Apoptosis or programmed cell death is an inherently programmed phenomenan (Kerr et al, 1972) that occurs in each(prenominal) multicellular organisms, described as the opposite of mitosis, necessary in providing homeostasis and preventing uncontrollable cell proliferation that whitethorn run short to tumour imageation. humiliation is also a form of cell death, polar to apoptosis in that it is externally generate by factors such as injury, infection, poisoning and inflammation. Apoptosis operates via two mechanisms, an intrinsic pathway initiated by the release of cytochrome c from mitochondrial membranes, or an extrinsic pathway initiated by the activation of surface death receptors by proapoptotic molecules such as caspase 8. Both pathways however lead to common morphological and biochemical features, that are characteristic of apoptosis, such as DNA fragmentation, chromatin condensation, membrane blebbing, cell shoplifting and formation of apoptotic bodies (Kerr et al, 1972). The formation of apoptotic bodies during primordial stages of apoptosis, is cause by the inversion of phosphatidylserine (PS), from the inside plasma membrane to the exterior membrane, and is necessary for phagocyte light of the apoptotic cell.
The presence of PS, is indicative of cells in the early stage of apoptosis and can be spy using Annexin-V, a phospholipid bind protein with a high kinship toward PS in the presence of calcium ions. Annexin-V is usually combine with fluorescein i sothiocyanate (FITC), a fluorescent fixture! molecule that allows the detection of apoptotic cells by flow cytometry. Figure 1: Translocation of PS to the outer cell membrane, and detection by Annexin-V binding. (MCBG3004 testing ground Manual, 2011). Fluorescence activated cell see (FACS), is an analytical technique used to identify and separate different cells types by using fluorescent marker molecules such as FITC, that emit light of...If you indirect request to get a dependable essay, order it on our website: OrderCustomPaper.com
