Abstract | Human leukocyte antigen class I (HLA-I) molecules are a group of structurally-related cell surface proteins with a high degree of variability within the population. While only up to six variants are expressed in an individual person, the whole population contains thousands of different variants. The ability to distinguish specific variants is important in the clinic to determine compatibility during organ and bone marrow transplantation and in the laboratory to study the biological properties of individual variants. Solid phase bead arrays contain purified, individually identifiable HLA-I molecules that can be used to determine antibody specificity for individual HLA-I proteins. This method is high-throughput, highly specific, and allows for simultaneous screening of antibodies against multiple HLA-I allotypes. The beads are particularly useful for screening patient sera for the presence of donor-specific antibodies against individual HLA-I variants (which can arise during pregnancy, blood transfusion, or organ transplantation). Alternate approaches, such as the use of individual HLA-I-expressing cell lines, are more time consuming, and such cell lines are difficult to procure and standardize. The HLA-I beads are also useful to study HLA-I specificity and selectivity for other receptors and binding partners. |
