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.
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.
Phytohaemagglutinin, a toxic lectin, is present in many varieties of common bean but is especially concentrated in red kidney beans. The lectin has several effects on cell metabolism; it induces mitosis and affects the cell membrane regarding transport and permeability to proteins. It agglutinates most mammalian red blood cell types ...
Steak is also a good source of vitamin B12, "which is crucial for energy levels, brain health, and red blood cell production," says Alex Larson, a registered dietitian, endurance athlete ...
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 ...
Pokeweed mitogen has the ability to play a role in immunology.It can test for immunodeficiency by inducing cell proliferation and test for abnormal counts of lymphocytes. [2]
The Jurkat cell line (originally called JM) was established in the mid-1970s from the peripheral blood of a 14-year-old boy with T cell leukemia. [2] [3] Different derivatives of the Jurkat cell line that have been mutated to lack certain genes can now be obtained from cell culture banks.
In blood grouping, the patient's serum is tested against RBCs of known blood groups and also the patient's RBCs are tested against known serum types. In this way the patient's blood group is confirmed from both RBCs and serum. A direct Coombs test is also done on the patient's blood sample in case there are any confounding antibodies.
