Phytohaemagglutinin (PHA, or phytohemagglutinin) is a lectin found in plants, especially certain legumes. PHA actually consists of two closely related proteins, called leucoagglutinin (PHA-L) and PHA-E. These proteins cause blood cells to clump together. PHA-E cause erythrocytes (red blood cells) to clump.

Some of the glycolipids and glycoproteins on an individual's red blood cells can be identified by lectins. A lectin from Dolichos biflorus is used to identify cells that belong to the A1 blood group. A lectin from Ulex europaeus is used to identify the H blood group antigen. A lectin from Vicia graminea is used to identify the N blood group ...
Blood tests are common, but can cause fear or anxiety for some. Fox News Digital spoke with a doctor about what you can do to be prepared and comfortable before your next blood draw.
Illustration showing influenza virus attaching to cell membrane via the surface protein hemagglutinin. Hemagglutinins (alternatively spelt haemagglutinin, from the Greek haima, 'blood' + Latin gluten, 'glue') are homotrimeric glycoproteins present on the protein capsids of viruses in the Paramyxoviridae and Orthomyxoviridae families.
Mitogens can be either endogenous or exogenous factors. Endogenous mitogens function to control cell division is a normal and necessary part of the life cycle of multicellular organisms.
This image explains agglutination in the blood. 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.
