Identify lectin reagents that show ABO blood group specificity. Assess the effects of disease and age on production of ABO antigens and antibodies. Classify the A and B antigens into subgroups, including serologic characteristics, number of antigen sites and frequency in the population.

Blood Group Antigen Glycan Array User Manual

The blood group antigen (BGA) glycan array is an advanced, high-throughput tool that allows screening of relatively small amounts of serum samples or other BGA-binding samples of interest to determine the reactivity of antibodies or proteins that would interact with specific blood groups.

Blood Group Changes with Aging. Blood group antigens have been found to be present in fetal tissue. At birth, blood group antigens generally exhibit a weaker expression. At about 3 years of age, blood group antigens reach the full strength of their expression. The number of antigen sites on the cell surface ranges from 120,000 up to > 1 million

Anti-P1 Antibody

Today, the P1 antigen belongs to the P1PK blood group system. Other members of the system include the P. k. and NOR antigens. The closely related P antigen formerly belonged to this system, but now resides in its own system called Globoside along with the PX2 antigen. 3. The following phenotypes have been reported: 2.

Anti-G is an antibody directed against the G antigen in the Rh blood group system. The G antigen is found on red cells possessing C or D antigen. Anti-G has been implicated in Transfusion Reactions and Hemolytic Disease of the Fetus and Newborn. Patients with Anti-G must receive D(Rh)- and C- blood.

Studies on the genetic basis of Pk, P and P1 blood group

A group of antigens that does not yet fulfil the requirements for a blood group system can be assigned a blood group collection number instead. There are also series for both high (the 901 series) and low (the 700 series) incidence antigens that have no association to any other antigen or blood group system.

The ABO Blood Group System. The ABO blood group is determined by the A or B antigen attached to the membrane of the red blood cell. Group A persons inherit the A antigen and make anti-B antibodies which destroy cells carrying B antigens. Group B persons inherit the B antigen and make anti-A antibodies which destroy cells carrying A antigens.
