Mitochondrial outer membrane permeabilization (MOMP), also known as the mitochondrial outer membrane permeability, is one of two ways apoptosis (a type of programmed cell death) can be activated. [1] It is part of the intrinsic pathway of apoptosis, also known as the mitochondrial pathway. MOMP is known as the point of no return in apoptosis.
Cuvettes for in-vitro electroporation. These are plastic with aluminium electrodes and a blue lid. They hold a maximum of 400 μl.. Electroporation, or electropermeabilization, is a technique in which an electrical field is applied to cells in order to increase the permeability of the cell membrane.
Intracellular delivery is the process of introducing external materials into living cells. Materials that are delivered into cells include nucleic acids (DNA and RNA), proteins, peptides, impermeable small molecules, synthetic nanomaterials, organelles, and micron-scale tracers, devices and objects.
In these cases, a 'quick fix' method using cold formalin for around 24 hours is typically used. Methanol (100%) can also be used for quick fixation, and that time can vary depending on the biological material. For example, MDA-MB 231 human breast cancer cells can be fixed for only 3 minutes with cold methanol (-20 °C). For enzyme localization ...
Lithium acetate is also used to permeabilize the cell wall of yeast for use in DNA transformation. It is believed that the beneficial effect of LiOAc is caused by its chaotropic effect; denaturing DNA, RNA and proteins. [2]
The glycocalyx (pl.: glycocalyces or glycocalyxes), also known as the pericellular matrix and cell coat, is a layer of glycoproteins and glycolipids which surround the cell membranes of bacteria, epithelial cells, and other cells. [1] Animal epithelial cells have a fuzz-like coating on the external surface of their plasma membranes.
Buoyed by promised pardons of their brethren for their Jan. 6 crimes and by Trump’s embrace of popular extremist far-right figures, those groups will likely see a resurgence after January ...
Pulsed electric fields were used to temporarily permeabilize cell membranes to deliver foreign DNA into cells. In the following decade, the combination of high-voltage pulsed electric fields with the chemotherapeutic drug bleomycin and with DNA yielded novel clinical applications: electrochemotherapy and gene electrotransfer , respectively.
