It is released from damaged cells and is a biomarker for cellular cytotoxicity and cytolysis. The released LDH is measured with a …
Cytolysis, also known as osmotic lysis, occurs when a cell bursts and releases its contents into the extracellular environment due to a great influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume. This is a concern particularly for cells that do not have a tough … See more Cytolysis can be caused by many factors, from the tonicity of the extracellular fluid to the activity of other cells affecting the structure of the cell membrane. See more Cytolysis is often used as a tool of survival by various cells. While single celled organisms and pathogens use it to repel attack or gain access to new hosts, multicellular … See more In spite of its many uses, it is important for an organism to control when and how cytolysis occurs. Plants have a natural defense mechanism against cytolysis because they contain … See more WebMay 13, 2007 · ADCC activity and complement-dependent cytolysis activity were analyzed using the CytoTox 96 assay. ADCC activities correlated with the EGFR expression value ( R = 0.924). ADCC activities were detected against all tumor cell lines, except K562 cells in a manner dependent on the cellular EGFR expression level, whereas complement-dependent …
