What does lysis mean?

(LY-sis) In biology, lysis refers to the breakdown of a cell caused by damage to its plasma (outer) membrane. It can be caused by chemical or physical means (for example, strong detergents or high-energy sound waves) or by infection with a strain virus that can lyse cells.

What happens during lysis?

To lyse is to break apart a larger particle into smaller pieces. Lysis, or the process of lysing, can occur both inside and outside of the cell. While localized lysis can result in a tiny puncture of a cell wall or cell membrane, harsher chemical lyses result in the expulsion of all cellular contents and cell death.

What is an example of lysis?

Lysis: Destruction. Hemolysis is the destruction of red blood cells with the release of hemoglobin; bacteriolysis is the destruction of bacteria; etc. Lysis can also refer to the subsidence of one or more symptoms of an acute disease as, for example, the lysis of fever in pneumonia.

What is lysis used for?

Lysis refers to the breaking down of the cell, often by viral, enzymic, or osmotic mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a "lysate". Cell lysis is used to break open cells to avoid shear forces that would denature or degrade sensitive proteins and DNA.

What is meant by hematopoiesis?

Definition of hematopoiesis

: the formation of blood or of blood cells in the living body.

What does Pathy mean in medical terms?

pathy: A suffix derived from the Greek "pathos" meaning "suffering or disease" that serves as a suffix in many terms including myopathy (muscle disease), neuropathy (nerve disease), retinopathopathy (disease of the retina), sympathy (literally, suffering together), etc.

What do lysed cells look like?

On the contrary, you can spot lysed yeast cells without staining, they appear like empty, shrunk cell walls, called "ghosts". if you want to monitor lysis, you centrifuge your samples and analyse protein or DNA content in the supernatant after centrifugation.

What causes cellular death?

Necrosis: occurs when a cell dies due to lack of a blood supply, or due to a toxin. The cells' contents can leak out and damage neighbouring cells, and may also trigger inflammation. Necroptosis: is similar in appearance to necrosis, in that the dying cell's contents can leak out.

What can trigger the virus to go into lytic cycle?

In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to excise and enter the lytic cycle.

What is lysis in fever?

1 : the gradual decline of a disease process (such as fever) 2 : a process of disintegration or dissolution (as of cells) -lysis. noun combining form. plural -lyses.

What does it mean to crenate?

: having the margin or surface cut into rounded scallops a crenate leaf.

What does Plasmolyzed mean in biology?

Plasmolysis is a typical response of plant cells exposed to hyperosmotic stress. The loss of turgor causes the violent detachment of the living protoplast from the cell wall. The plasmolytic process is mainly driven by the vacuole. Plasmolysis is reversible (deplasmolysis) and characteristic to living plant cells.

What causes lysis?

Lysis in the laboratory may be affected by enzymes or detergents or other chaotropic agents. Mechanical disruption of cell membranes, as by repeated freezing and thawing, sonication, pressure, or filtration may also be referred to as lysis.

How do you do cell lysis?

The technique involves freezing a cell suspension in a dry ice/ethanol bath or freezer and then thawing the material at room temperature or 37°C. This method of lysis causes cells to swell and ultimately break as ice crystals form during the freezing process and then contract during thawing.
