  2. Zeta potential - Wikipedia

    en.wikipedia.org/wiki/Zeta_potential

    The zeta potential is an important and readily measurable indicator of the stability of colloidal dispersions. The magnitude of the zeta potential indicates the degree of electrostatic repulsion between adjacent, similarly charged particles in a dispersion. For molecules and particles that are small enough, a high zeta potential will confer ...

  3. Red blood cell - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell

    The zeta potential is an electrochemical property of cell surfaces that is determined by the net electrical charge of molecules exposed at the surface of cell membranes of the cell. The normal zeta potential of the red blood cell is −15.7 millivolts (mV). [35]

  4. Potentiator - Wikipedia

    en.wikipedia.org/wiki/Potentiator

    Albumin acts as a potentiator by reducing the zeta potential around the suspended red blood cells, thus dispersing the repulsive negative charges and enhancing agglutination. Low ionic strength saline (LISS) is a potentiator that acts by not only reducing the zeta potential , but also by increasing the amount of antibody taken up by the red ...

  5. Double layer (surface science) - Wikipedia

    en.wikipedia.org/wiki/Double_layer_(surface_science)

    Electric potential difference between the fluid bulk and the surface is called the electric surface potential. Usually zeta potential is used for estimating the degree of DL charge. A characteristic value of this electric potential in the DL is 25 mV with a maximum value around 100 mV (up to several volts on electrodes [22] [27]).

  6. Coombs test - Wikipedia

    en.wikipedia.org/wiki/Coombs_test

    The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent").

  7. Erythrocyte sedimentation rate - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_sedimentation_rate

    The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation .

  8. Electrokinetic phenomena - Wikipedia

    en.wikipedia.org/wiki/Electrokinetic_phenomena

    capillary osmosis, as motion of liquid in porous body under influence of the chemical potential gradient; sedimentation potential, as electric field generated by sedimenting colloid particles; streaming potential/current, as either electric potential or current generated by fluid moving through porous body, or relative to flat surface;

  9. Erythropoietin - Wikipedia

    en.wikipedia.org/wiki/Erythropoietin

    Erythropoietin (/ ɪ ˌ r ɪ θ r oʊ ˈ p ɔɪ. ɪ t ɪ n,-r ə-,-p ɔɪ ˈ ɛ t ɪ n,-ˈ iː t ɪ n /; [1] [2] [3] EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow.
