"The principle of the MAIEA technique depends on the binding of two antibodies made in different species to different determinants on the same membrane component to form of a tri-molecular complex [4]. Briefly, a murine monoclonal antibody (MAb) and human antibody are incubated simultaneously with red cells. Excess antibody is removed, the sensitized cells are solubilised with Triton, so the tri-molecular complex is released into solution. The complex is detected by an ELISA type assay. The tri-molecular complex is captured by an anti-mouse globulin precoated onto a microtitre plate. The human antibody is then detected by a peroxidase-conjugated anti-human IgG. A positive reaction gives a high absorbance value and a negative reaction gives a low absorbance value. A negative result is obtained when the antibodies used bind to different membrane components, so no tri-molecular complex is formed. A negative result is also obtained when the monoclonal antibody and human antibody compete for the same epitope. Results can be represented as ratios of absorbances for antigen positive to antigen negative cells or as bar charts. In these studies a murine anti-CR1 (E11) and human anti-Kna and other Knops system antibodies were used against antigen positive and antigen negative cells. Absorbances for antigen positive cells with anti-Kna, anti-McCa anti-Sla and anti-Yka were high and results for the antigen-negative cells were low [8]. Comparison of chymotrypsin treated Kn(a+) cells with Kn(a-) cells showed that chymotrypsin did indeed destroy Kna antigen; chymotrypsin treated cells, therefore, were suitable cells to use as antigen negative cells when cells of rare phenotype were not available [8]. These reactions gave significantly positive ratios (Table I). In contrast, low absorbances were recorded for Cs(a+) and Cs(a-) cells with anti-Csa, the 1:1 ratio indicating a negative result (Table I). Serologically the Helgeson phenotype cells have a Knops null phenotype, all 4 antigens are negative but the antigens could be detected by flow cytometry and in immune precipitation [6,7]. Moulds and colleagues provided an explanation for this when they found that such cells did not completely lack CR1 but had a low copy number of CR1 molecules per cell [9]. Had it not been known already, the presence of Knops system antigens on Helgeson phenotype cells could have been deduced from the MAIEA results. The absorbance values for Helgeson phenotype cells were significantly higher than for antigen negative cells for Kna, McCa and Yka [8]. MAIEA has confirmed that Kna, McCa, Sla and Yka but not Csa are associated with the CR1 molecule in the red cell membrane and can detect weak expression of CR1 antigens on Helgeson phenotype cells [8]. MAIEA is useful for investigating problem antibodies suspected to be Knops system antibodies and can also be used to Knops phenotype cells with poor expression of Knops system antigens."

"roles of carrier proteins. The identification and usefulness of blood group antigens as markers will be described and possible explanations for their variation in expression will be discussed. Most red cell antigens have been investigated because they are clinically important [1]. The antibodies to some antigens have caused haemolytic disease of the newborn and/or transfusion reactions. Other antigens are involved in haemolytic anaemia and some are important in transplantation. Red cell antigens provided a tool for investigation of the red cell surface and for use as genetic, immunological and biochemical markers. More than 500 red cell antigens are serologically defined, about half of which have been officially recognised and have been numbered by the International Society of Blood Transfusion Working Party on Terminology for Red Cell Surface Antigens [2,3]. Antigens are divided into systems (antigens controlled by a locus or closely linked loci) and three holding files: collections (related antigens whose genetic relationship is unknown), antigens of high incidence or antigens of low incidence. THE MAIEA TECHNIQUE Sometimes if an antigen has a very high or a very low incidence it is hard to relate it to other antigens or to assign it to a system. Immunochemical studies and in the case of high incidence antigens, use of cells of rare phenotype can be informative and recently the MAIEA technique, monoclonal antibody specific immobilisation of erythrocyte antigens, has proved useful. MAIEA was an adaptation of a technique, MAIPA, frequently used for studying platelets. MAIEA can be used to assign red cells antigens, as recognised by human alloantisera, to particular components of the red cell membrane [4]. Location of antigens on specific red cell membrane components The Knops system consists of 4 high incidence antigens Kna, McCa, Sla and Yka with frequencies greater than 90% in populations tested. There is also a low incidence antigen Knb found in Whites [3]. The antibodies to these public antigens are difficult to identify serologically. The antigens show a wide variation of strength on different donor’s cells. There is a null phenotype, the Helgeson phenotype, which appears from serological tests to lack all 4 antigens [5]. Cells which lack one Knops antigen may have weakened expression of other Knops antigens. The mists about these serologically difficult antigens were cleared when Moulds et al [6] and Rao et al [7] independently showed that these antigens were carried on the CR1 (complement receptor 1, CD35) protein. The related antigen Csa was not located on CR1, so Csa and Csb were left in the Cost collection [3]." In Transfusion Immunology and Medicine.
