ABO system

All the common blood types, such as the ABO system, are genetic polymorphisms.

Each type of blood in the ABO system also has a positive or negative Rh factor.

Efficacy of chemo and immunochemistry in neuro-oncological patients with different ABO system blood group.

The most important blood type classification systems are the ABO system and the Rh system.

These antigens were an early discovery and are some of the oldest blood antigens known after the ABO system.

Regular antibodies usually refer to the isohemagglutinins, directed against antigens of the ABO system.

The ABO system is the most important blood-group system in human-blood transfusion.

In addition to the ABO system, the Rh blood group system can affect transfusion compatibility.

For example, if you have "A+ blood," it means your blood is type A in the ABO system and your Rh factor is positive.

Histo-blood group ABO system transferase is an enzyme with glycosyltransferase activity which in humans is encoded by the ABO gene.

Unlike the ABO system, in which the antibodies to other blood types develop from birth, Rh- people do not make an antibody to the Rh antigen unless they are first sensitized.

The H gene of the ABO system encodes a fucosyl transferase that adds fucose to type 2 precursor substances on the surface of RBCs to make H antigen.

A. The most basic classification of the hundreds of ways to type human blood, the ABO system, is important because incompatible types of blood react with each other to form sticky globs of red blood cells that can cause serious and sometimes fatal blockages.

In the Lewis System there are two possible antigens that can be produced, called Lewis a and Lewis b (not to be confused with the A and B of the ABO system), and their interplay determines your secretor status.
