Both methods are very useful for clinical and research purposes and can provide generic (low resolution) to allelic (high resolution) typing results. This chapter provides an overview of the SSO and SSP methods in relation to HLA typing.
HLA typing is done by serological typing methods or molecular typing methods. The serologic HLA typing methods detect the epitopes of the HLA molecules, whereas the molecular methods detect the nucleotide sequences. i. HLA typing that defines groups of alleles (usually approximating serologic specificities) is referred to as low-resolution or generic typing (For example, HLA- DRBl-04). ii.
Control sequences representing known allelic polymorphisms at the locus in question are subjected to the labelled probe along with the sample. Human leukocyte antigen (HLA) typing, utilising the sequence-specific oligonucleotide (SSO) and sequence-specific primer (SSP) technologies, has been in routine use in many tissue typing laboratories worldwide for more than 20 years since the development of the polymerase chain reaction. Both methods are very useful for clinical and research purposes and can provide generic (low resolution) to Se hela listan på itl.ucsf.edu Why BGI for HLA typing. High resolution: Employs the international gold standard method to provide HLA typing at 4-digit resolution.; Accurate: 100% accuracy achieved in 25 consecutive external quality assessments from the UCLA International HLA DNA Exchange program. workup, one of the tests performed is HLA typing to determine the patient’s HLA antigens (flags).

Methods in molecular biology Human leukocyte antigen (HLA) typing, utilising the sequence-specific oligonucleotide (SSO) and sequence-specific primer (SSP) technologies, has been in routine use in many tissue typing laboratories worldwide for more than 20 years … Overview on HLA and DNA typing methods. The term HLA refers to the Human Leukocyte Antigen System, which is controlled by genes on the short arm of chromosome six. The HLA loci are part of the genetic region known as the major histocompatibility complex (MHC).
Transplant rejection is one of the most common causes for the failure of a transplant procedure. 2010-09-09 2010-05-01 2004-09-13 2019-03-01 HLA testing is challenging due to its high polymorphic nature and high levels of sequence homology between the loci; Using conventional typing methods, Serology, SSP, SSO, and SBT, are laborious and time-consuming which may not resolve ambiguities between homologous regions at allelic resolutions Novel HLA Typing Method Identifies HLA Alleles Associated with Pediatric ITP Taylor Olmsted Kim, MD, Taylor Olmsted Kim, MD 1 Baylor College of Medicine, Department of Pediatrics, Section of Hematology/Oncology, Houston, TX .
An HLA typing with less ambiguity produces fewer high-probability haplotypes and a more reliable prediction. We estimated ambiguity for several HLA typing methods across four continental populations using an information theory-based measure, Shannon's entropy.
2 Texas Children's Cancer and Hematology Centers, Houston, TX . We estimated ambiguity for several HLA typing methods across four continental populations using an information theory-based measure, Shannon's entropy. We used allele and haplotype frequencies to calculate entropy for different sets of 1,000 subjects with simulated HLA typing.
RT-PCR is another approach to HLA typing that is fast and versatile, but it is expensive. Reference strand-mediated conformational analysis (RSCA) is yet another method used for HLA typing. In this method, an unknown HLA sample is mixed with a reference allele and run in a gel by electrophoresis.

The LABType(®) SSO (One Lambda, Inc) and Gen-Probe LIFECODES HLA-SSO HLA Typing tests are rapid and efficient assays for determining human leukocyte antigens (HLAs). The principle of these assays involves the hybridization of reverse sequence-specific oligonucleotide probes each attached to a unique colour coded microsphere to identify HLA class I and class II alleles. The clinical applications of HLA typing most commonly inlcude (1) typing for renal transplantation as one component in the scheme to allocate deceased donor kidneys to individuals on the renal transplant waiting list because of the long-term benefit of using HLA-matched kidneys, (2) typing for hematopoeitic stem cell transplantation (HSC) as it is well known that the degree of HLA match between donor and …
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. 2017-11-28

2012-04-26 2020-08-13 RT-PCR is another approach to HLA typing that is fast and versatile, but it is expensive. Reference strand-mediated conformational analysis (RSCA) is yet another method used for HLA typing. In this method, an unknown HLA sample is mixed with a reference allele and run in a gel by electrophoresis. The HLA typing methods are used to determine whether an individual's body will accept or reject foreign tissue. The human body uses the HLA typing of the tissue to determine whether it is foreign tissue or not. Transplant rejection is one of the most common causes for the failure of a transplant procedure.
