DOI https://doi.org/10.1007/978-1-59745-223-6_4; Publisher Name Humana Press Most molecular HLA typing methods are based on the group-specific amplification by PCR where the PCR-SSP technique is widely used to detect HLA-B* 27 . In this study, we developed an in-house PCR-SSP test which amplifies all the HLA-B* 27 alleles (27:01–27:73) except B* 27:18 and B* 27:23, which have not been reported from Asian population. PCR-SSP for HLA Tissue Typing The PCR-SSP technique first appeared in the early 1990s and was based on the amplification of refractory mutation systems (ARMS). The principle of this method is that a perfectly matched primer is more efficient in a PCR reaction than one or more mismatched primers. Olerup O, Zetterquist H (1992) HLA-DR typing by PCR amplification with sequence-specific primers (PCR-SSP) in 2 hours: an alternative to serological DR typing in clinical practice including donor-recipient matching in cadaveric transplantation. Sequence-specific amplification (SSP) is simply a form of polymerase chain reaction (PCR) which involves designing one or both primers so that they will or will not allow amplification (the 3'-mismatch principle).
HLA-DR typing was performed using standard microcytotoxicity assay and PCR-SSP method in 28 patients referred to our Transplantation Immunology Unit for HLA typing. Comparison of results obtained by both methods revealed no discrepancies in 5 patients, in 12 patients the PCR-SSP typing showed additional DR antigens or splits of antigens. HLA Typing Technologies. Designed to address the diverse needs of HLA labs, our molecular product family includes Next Generation Sequencing (NGS), sequence-based typing (SBT), Real-Time PCR (qPCR), sequence-specific primers (SSP), and reverse sequence-specific oligonucleotides (rSSO).

Unlike other PCR- HLA typing by sequence-specific primers (PCR-SSP) is a commonly used technique in HLA typing in which multiple pairs of cis-located allele-specific primers Current DNA-based methods that are in use for HLA typing are polymerase chain reaction-sequence-specific priming (PCR-SSP). Polymerase chain reaction- PCR-SSP for HLA Tissue Typing. The PCR-SSP technique first appeared in the early 1990s and was based on the amplification of refractory mutation systems ( used in tissue typing laboratories. Various techniques are currently employed, including PCR-sequence-spe- cific primer (PCR-SSP) (Bunce et al., 1995), PCR-. Invitrogen products specifically to perform HLA typing utilizing the Sequence Specific Primer (SSP) methodology and the Sequence-Based Typing (SBT) 9 Mar 2011 Human leukocyte antigen (HLA) typing is essential to carry out HLA-class I restricted antigenic peptide-based cancer immunotherapy. Various PCR based HLA class II DNA typing methods have been developed and applied.
HLA-DR typing was performed on a random caucasian population consisting of 31 patients and 73 healthy individuals. Considering HLA-DR1-10, differences in typing results were found in 3 out of 73 healthy individuals and 8
HLA typing by sequence-specific oligonucleotides probes (PCR-SSOP) Example of hybridization specificity with SSO probes. The combination of PCR technology and hybridization with sequence-specific oligonucleotide probes was first applied to HLA class II typing because of the limitations of DR serology and of the better knowledge of allelic polymorphism at DR/DQ loci. Most molecular HLA typing methods are based on the group-specific amplification by PCR where the PCR-SSP technique is Results more widely used to detect HLA-DRb1*04 alleles. Addi- tionally, PCR-SSOP and Luminex methods are described The presence of a 259-bp specific band along with 434-bp as well for identifying the HLA alleles.

Methods. The real-time PCR method their Class II HLA antigens were all defined by the PCR-SSP method. Molecular typing was adequate for patients with low B lymphocytes quantity and quality. Qualitative SSP-PCR in vitro for diagnosis HLA class I and class II alleles typing kit with low or high resolution. Request information.
At least two PCR-SSP methods for gen- eric typing of HLA-DR specificities have been pub- lished (4, 5), as has a PCR-SSP method for the Brief communication volume of 20 pl. All reagents but the Taq Poly- merase were pre-mixed and stored at -20°C in order to speed the process of typing.

HLA DR typing by PCR-SSP: Advantages and inconveniences after six months of routine use in three laboratories Dominique Charron HLA-A locus specificities identified by Sequence Specific PCRWe have established a system for typing the HLA Class I 'A' locus from genomic DNA, by a one-step polymcrase chain reaction (PCR) based on ARMS (Amplification Refractory Mutation System l). In conclusion, we have successfully developed a simple, convenient, and cost-effective PCR-SSP technique for HLA-B* 27 typing which is a reliable diagnostic test for AS and related SpA diagnosis. This test can now be routinely applied for HLA-B* 27 genotyping in all tissue typing laboratories. HLA-Ready Gene DRDQDP plus +Taq with DQ/DP alpha and beta-chains More safety - whole system is CE certified More comfort - 1 tube of ReadyMix including Taq per typing Fast HLA typing based on sequence-specific primers is ideally suited for smaller numbers of samples and confirmatory tests.
