  2. Mitochondrial outer membrane permeabilization - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_outer...

    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.

  3. Electroporation - Wikipedia

    en.wikipedia.org/wiki/Electroporation

    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.

  4. Intracellular delivery - Wikipedia

    en.wikipedia.org/wiki/Intracellular_delivery

    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.

  5. Heterocyst - Wikipedia

    en.wikipedia.org/wiki/Heterocyst

    Heterocysts or heterocytes are specialized nitrogen-fixing cells formed during nitrogen starvation by some filamentous cyanobacteria, such as Nostoc, Cylindrospermum, and Anabaena. [1] They fix nitrogen from dinitrogen (N 2) in the air using the enzyme nitrogenase, in order to provide the cells in the filament with nitrogen for biosynthesis. [2]

  6. Expansion microscopy - Wikipedia

    en.wikipedia.org/wiki/Expansion_microscopy

    Linking is the process of adding a polymer gel to the cells, which permeabilize through the cell. The linking step also includes, as the name suggests, the process of linking the fluorophores to the gel. The digestion step involves adding a solution that digests the cell, removing the structure from the cell.

  7. Cell engineering - Wikipedia

    en.wikipedia.org/wiki/Cell_engineering

    Cell engineering is the purposeful process of adding, deleting, or modifying genetic sequences in living cells to achieve biological engineering goals such as altering cell production, changing cell growth and proliferation requirements, adding or removing cell functions, and many more.

  9. Fixation (histology) - Wikipedia

    en.wikipedia.org/wiki/Fixation_(histology)

    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 ...
