  2. Lysis buffer - Wikipedia

    en.wikipedia.org/wiki/Lysis_buffer

    It may be the most widely used lysis buffer. The solubilizing agent is NP-40, which can be replaced by other detergents at different concentrations. Since NP-40 is a nonionic detergent, this lysis buffer has a milder effect than RIPA buffer. It can be used when protein functions are to be retained with minimal disruption. [9] Recipe: [9] 150 mM ...

  3. Hemolysis - Wikipedia

    en.wikipedia.org/wiki/Hemolysis

    A red blood cell in a hypotonic solution, causing water to move into the cell A red blood cell in a hypertonic solution, causing water to move out of the cell. Hemolysis or haemolysis (/ h iː ˈ m ɒ l ɪ s ɪ s /), [1] also known by several other names, is the rupturing of red blood cells (erythrocytes) and the release of their contents into surrounding fluid (e.g. blood plasma).

  4. Washed red blood cells - Wikipedia

    en.wikipedia.org/wiki/Washed_red_blood_cells

    Washed red blood cells are red blood cells that have had most of the plasma, platelets and white blood cells removed and replaced with saline or another type of preservation solution. [ 1 ] [ 2 ] The most common reason for using washed red blood cells in transfusion medicine is to prevent the recurrence of severe allergic transfusion reactions ...

    The different stages of the method are lyse, bind, wash, and elute. [1] [2] More specifically, this entails the lysis of target cells to release nucleic acids, selective binding of nucleic acid to a silica membrane, washing away particulates and inhibitors that are not bound to the silica membrane, and elution of the nucleic acid, with the end result being purified nucleic acid in an aqueous ...

  6. Hemolysis (microbiology) - Wikipedia

    en.wikipedia.org/wiki/Hemolysis_(microbiology)

    Beta-hemolysis (β-hemolysis), sometimes called complete hemolysis, is a complete lysis of red cells in the media around and under the colonies: the area appears lightened (yellow) and transparent. [1] Streptolysin, an exotoxin, is the enzyme produced by the bacteria which causes the complete lysis of red blood cells. There are two types of ...

  7. Lysis - Wikipedia

    en.wikipedia.org/wiki/Lysis

    Lysis (/ ˈ l aɪ s ɪ s / LY-sis; from Greek λῠ́σῐς lýsis 'loosening') is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, "lytic" / ˈ l ɪ t ɪ k / LIT-ik) mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate.

  8. Sucrose lysis test - Wikipedia

    en.wikipedia.org/wiki/Sucrose_lysis_test

    The sucrose lysis test is a diagnostic laboratory test used for diagnosing paroxysmal nocturnal hemoglobinuria (PNH), as well as for hypoplastic anemias and any hemolytic anemia with an unclear cause. [1] The test works by using sucrose, which creates a low ionic strength environment that allows complement to bind to red blood cells. [1]

  9. Erythrocyte fragility - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_fragility

    Erythrocyte fragility refers to the propensity of erythrocytes (red blood cells, RBC) to hemolyse (rupture) under stress. It can be thought of as the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to stress (typically physical stress, and most commonly osmotic and/or mechanical stress). Depending on ...
