ABO blood group system - Wikipedia
https://en.wikipedia.org/wiki/ABO_blood_group_systemThe ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes. For human blood transfusions, it is the most important of the 43 different blood type (or group) classification systems currently recognized by the International Society of Blood Transfusions (ISBT) as of June 2021. A mismatch (very rare in modern …
Blood type - Wikipedia
https://en.wikipedia.org/wiki/Blood_typeA blood type (also known as a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.Some of these antigens are also present on the surface of other …
Rh blood group system - Wikipedia
https://en.wikipedia.org/wiki/Rh_blood_group_systemThe Rh blood group system is a human blood group system.It contains proteins on the surface of red blood cells. After the ABO blood group system, it is the most likely to be involved in transfusion reactions.The Rh blood group system consists of 49 defined blood group antigens, among which the five antigens D, C, c, E, and e are the most important. . There is no …
P1PK blood group system - Wikipedia
https://en.wikipedia.org/wiki/P1PK_blood_group_systemP1PK (formerly: P) is a human blood group system (International Society of Blood Transfusion system 003) based upon the A4GALT gene on chromosome 22.The P antigen (later renamed P1) was first described by Karl Landsteiner and Philip Levine in 1927. The P1PK blood group system consists of three glycosphingolipid antigens: P k, P1 and NOR. In addition to …
Blood - Wikipedia
https://en.wikipedia.org/wiki/BloodThe ABO blood group system was discovered in the year 1900 by Karl Landsteiner. Jan Janský is credited with the first classification of blood into the four types (A, B, AB, and O) in 1907, which remains in use today. In 1907 the first blood transfusion was performed that used the ABO system to predict compatibility.
Red blood cell - Wikipedia
https://en.wikipedia.org/wiki/Red_blood_cellA typical human red blood cell has a disk diameter of approximately 6.2–8.2 µm and a thickness at the thickest point of 2–2.5 µm and a minimum thickness in the centre of 0.8–1 µm, being much smaller than most other human cells.These cells have an average volume of about 90 fL with a surface area of about 136 μm 2, and can swell up to a sphere shape containing 150 fL, without …
ABO (gene) - Wikipedia
https://en.wikipedia.org/wiki/ABO_(gene)Histo-blood group ABO system transferase is an enzyme with glycosyltransferase activity, which is encoded by the ABO gene in humans. It is ubiquitously expressed in many tissues and cell types. ABO determines the ABO blood group of an individual by modifying the oligosaccharides on cell surface glycoproteins. Variations in the sequence of the protein between individuals …
Human blood group systems - Wikipedia
https://en.wikipedia.org/wiki/Human_blood_group_systemsThe term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", and include the …
Hemolytic disease of the newborn (ABO) - Wikipedia
https://en.wikipedia.org/wiki/Hemolytic_disease_of_the_newborn_(ABO)The ABO blood group system is the best known surface antigen system, expressed on a wide variety of human cells. For Caucasian populations about one fifth of all pregnancies have ABO incompatibility between the fetus and the mother, but only a very small minority develop symptomatic ABO HDN.
Diego antigen system - Wikipedia
https://en.wikipedia.org/wiki/Diego_antigen_systemThe Diego antigen (or blood group) system is composed of 21 blood factors or antigens carried on the Band 3 glycoprotein, also known as Anion Exchanger 1 (AE1).The antigens are inherited through various alleles of the gene SLC4A1 (Solute carrier family 4), located on human chromosome 17.The AE1 glycoprotein is expressed only in red blood cells and, in a shortened …
