설명

일반 설명

Digitonin, a steroidal saponin extracted from the purple foxglove plant (Digitalis purpurea), stands as a versatile non-ionic detergent crucial for cell biology and biochemical research. Its unique attributes position it as a valuable asset in the exploration of cellular membranes, membrane proteins, and intracellular components. Digitonin′s key properties and applications include its ability to solubilize membrane-bound proteins effectively while preserving their native conformation, making it an ideal tool for studying membrane protein interactions and activities.

Moreover, Digitonin selectively permeabilizes the cholesterol-rich plasma membrane, leaving organelle membranes intact. This feature facilitates the extraction and purification of specific organelles, contributing to the study of their functions and roles in cellular processes. The detergent′s capability to permeabilize diverse cell types allows the study of intracellular components and processes by introducing molecules, antibodies, or enzymes into cells. Additionally, Digitonin finds application in immunocytochemistry experiments, enabling the labeling and detection of intracellular proteins and structures.

애플리케이션

Digitonin has been used along with permeabilization buffer for cyclic guanosine monophosphate-adenosine monophosphate (cyclic GMP-AMP) stimulation in cells.

Digitonin has been used in a study to assess a procedure for isolating mitochondria from ascites tumor cells. It has also been used in a study to investigate its effect on the cytotoxicity of plant secondary metabolites in cancer cells.

생화학적/생리학적 작용

Digitonin plays a key role in permeabilizing cell membranes. It is capable of lysing eukaryotic cells but not bacterial membranes. It is also used to solubilize membrane components. It helps to create pores by interacting specifically with cholesterol in the membrane. It is preferred in biotechnology due to its mild detergency. This membrane-active compound act with doxorubicin against multi-drug resistant cancer cells.
