Area of Science:

  • Immunogenetics
  • Molecular Biology
  • Computational Biology

Background:

  • Southern blotting and hybridization with locus-specific HLA class II probes are of significant interest for HLA typing.
  • Restriction fragment patterns correlate with DR, DQ, and DP serological and cellular reactivities in homozygous cell lines.

Purpose of the Study:

  • To develop an interactive computer program for HLA-DR and DQ typing.
  • To address the challenges in interpreting complex restriction fragment patterns from heterozygous samples.

Main Methods:

  • Utilized Southern blotting and hybridization with locus-specific HLA class II probes.
  • Developed an interactive computer program for visual matching of restriction fragment patterns against standards from homozygous cell lines.
  • Incorporated an algorithm to estimate fragment sizes.
