Anti A1 Lectin

Anti-A1 lectin is a laboratory reagent used to determine blood type and detect the presence of the A1 antigen on red blood cells. The ABO blood typing system classifies blood into four major types: A, B, AB, and O, based on the presence or absence of specific antigens on the surface of red blood cells. The A1 antigen is a subtype of the A antigen, and is present in approximately 80% of people with type A blood. Anti-A1 lectin is a plant-derived lectin that binds specifically to the A1 antigen, and is used in blood typing procedures to distinguish between A1 and non-A1 blood types.

The use of anti-A1 lectin can be important in certain clinical situations, such as when a patient with a non-A1 blood type needs a blood transfusion from a donor with type A blood. In this case, it is important to ensure that the donor blood does not contain the A1 antigen, as this can cause a potentially life-threatening immune reaction in the recipient. While anti-A1 lectin is generally considered safe and effective when used by a trained laboratory professional, it is important to follow appropriate safety precautions and to properly dispose of any biohazardous waste generated during the blood typing process.
