る方法である。Recently, research on HLA has progressed, and the HLA gene has been identified and furthermore, the gene has been cloned. Since HLA is an antigen with a high degree of genetic winter-type characteristic, we used the cloned gene as a probe to detect HL based on the difference in the restriction enzyme cleavage pattern of the genetic DNA.
Attempts were made to differentiate type A (e.g., Japanese Patent Application Laid-open No. 1300-1983, which attempted to identify HLA class II DR antigen).

Determine the allotype of A antigen. In other words, when using each restriction enzyme, we know the size of the fragment produced by the rotaib as described above, so it can be determined from the size of the DNA fragment detected by electrophoresis. Its HLA type can be determined. As mentioned above, when a certain restriction enzyme is used, DNA fragments of the same size are often generated for multiple allotypes, but by applying multiple restriction enzymes in combination, HLA
Type determination can be performed.
