Agglutination is the clumping of particles. The word agglutination comes from the Latin agglutinare (glueing to). Agglutination is a reaction in which particles (as red blood cells or bacteria) suspended in a liquid collect into clumps usually as a response to a specific antibody.
Even the most fanatical fitness lover among us has "one of those days." You know, the kind of day that feels like it would be best spent under the covers 50 best workout songs for motivation ...
Red cell agglutination in a patient with cold agglutinin disease. In hematology, red cell agglutination or autoagglutination is a phenomenon in which red blood cells clump together, forming aggregates. It is caused by the surface of the red cells being coated with antibodies.
A typical HIIT session uses a 2:1 work-to-rest ratio, for example, 30–40 seconds of hard sprinting alternated with 15–20 seconds of jogging or walking, repeated to failure. The entire HIIT session may last between four and 30 minutes, meaning that it is considered to be an excellent way to maximize a workout limited by time constraints. [14]
Loud, high tempo music positively correlates with increased running rate and heart rate. [18] Higher tempo music, specifically music greater than 120 BPM, leads to what is called an ergogenic effect on physical performance; an ergogenic effect is any substance or mechanical device that leads to greater physical performance.
Since agglutination is not linked to infectivity, attenuated viruses can therefore be used in assays while an additional assay such as a plaque assay must be used to determine infectivity. By serially diluting a virus suspension into an assay tray (a series of wells of uniform volume) and adding a standard amount of blood cells, an estimation ...
As a result, the blood of a host applied to a diagnostic kit causes the aggregation of the pathogenic particles due to the antigen-agglutinin interaction. Conversely, agglutination can also be used to identify new bacteria or cells with a specific antigen by exposing them to serum containing known agglutinins. [3]
One example of the powerful biological attributes of lectins is the biochemical warfare agent ricin. The protein ricin is isolated from seeds of the castor oil plant and comprises two protein domains. Abrin from the jequirity pea is similar: One domain is a lectin that binds cell surface galactosyl residues and enables the protein to enter cells.
