The following are some of the serological methods used for HLA Typing: Microcytotoxicity assay: This is done by exposing the unknown lymphocyte to a battery of antisera of known HLA specificities.

HLA Typing Methods, Techniques and Results. HLA typing stands for Human Leukocyte Antigen typing. The HLA antigen is present on the surface of white blood cells. White blood cells form one of the key agents of the human immune system. There are various types given to different individuals.

2021-03-14 · Methods for HLA typing have evolved significantly since the first initial observations of anti-leukocyte antibodies over 50 years ago. Scientists now have a better understanding of the incredible genetic diversity of the HLA region which currently consists of over 28,000 different alleles.

The process is critical for identifying which people can safely donate bone marrow, cord blood, or an organ to a person who needs a transplant. HLA stands for human leukocyte antigen, but it is almost always referred to as HLA. The methods most widely used for HLA typing and clinical histocompatibility testing are based on the recognition of locus-specific polymorphisms in genomic DNA by sequence-specific primers (SSP) or by hybridization of sequence-specific oligonucleotide probes (SSOP) with DNA that has been selectively amplified by the PCR. Abstract.

This volume explores the rapidly evolving field of HLA typing and its use in both the laboratory setting and in silico methods. The chapters in this book discuss high-throughput methods for HLA typing; wet lab protocols; microarray data and its uses; in silico tools for the identification of HLA alleles from DNA and RNA next-generation-sequencing data, as well as HLA haplotype frequency Abstract. Histocompatibility testing is a specialized area of clinical laboratory science with particular relevance to transplant pro– grams. Although entailing several different specific functions, histocompatibility testing is most often equated with the deter– mination of the human leukocyte antigen (HLA) phenotype or genotype of an individual (referred to as HLA typing). In addition, full gene sequencing for HLA-DR, DQ and DP antigens is currently under validation.

Methods for HLA typing are described, including serological methods, molecular techniques of sequence-specific priming (SSP), sequence-specific oligonucleotide probing (SSOP), Sequence based Luminex-based technology has been applied to discriminate between the different Human Leukocyte Antigens (HLA) alleles. The typing method consists in a reverse-SSO assay: Target DNA is PCR-amplified using biotinylated group-specific primers. A single PCR reaction is used for each HLA locus.
