The 2 major subgroups of blood group A are A1 and A2. Anti-A1 Lectin is used to differentiate these subgroups. Group A red blood cells which are agglutinated with Anti-A1 Lectin are said to be of the subgroup A1. Those that do not agglutinate are majorly classified as A2. Agglutination of red cells that carry the A1 antigen occurs with the addition of the Anti-A1 reagent, following centrifugation. In the absence of the A1 antigen, no agglutination is generally observed. 

Fortress Anti-A1 blood grouping reagent is prepared from a Dolichos biflorus seed extract, diluted with a sodium chloride solution containing bovine albumin. This reagent is supplied ready for use and does not require any further dilution or addition.
