Because very few sequences are absolutely allele specific, SSP combine several primer to discriminate a particular allele unambigously. Resolution. The method can be applied for low resolution typing, using primer combinations that detect all alleles within a given serotype, as well as for high resolution typing. Low resolution HLA-A/B/DR typing can be achieved by a combination of 72 primer mixes. We have developed a method that allows the amplification of double-stranded DNA even when the sequence information is available at one end only ( 5 ). This method, the single specific primer-PCR (SSP-PCR), permits amplification of genes for which only a partial sequence information is available, and allows unidirectional genome walking from known into unknown regions of the chromosome. The PCR-SSP-based types of 166 regular blood donors and 148 cadaveric organ donors all showed total concordance with their serologically assigned ABO groups.

In PCR, the size of oligonuleotides used is 18 base pairs, while in assembly PCR lengths of up to 50bp are used to ensure correct hybridization. Red Blood Cell-Ready Gene is inno-train's product line for analysis of erythrocyte blood groups based on the SSP-PCR method. Therefore these diagnostic systems represent the ideal complement to serolgoical blood group typing. The modular kit design offers an extensive choice for a gradual typing system depending on your problem. We report a simple and rapid HLA-DRB1 generic typing method, PCR-SSP, which is practical and inexpensive.

All reagents but the Taq Poly- merase were pre-mixed and stored at -20°C in order to speed the process of typing.

a PCR-based HLA typing method utilising sequence-specific primers (PCR-SSP) which is applicable to the identification of all HLA class I and class II alleles, as. The authors performed polymerase chain reaction-sequence specific primer ( PCR-SSP) test for HLA-B27 to compare the results with serologic methods. Method 28 Feb 2020 Methods: Primers for each DQA1 and DQB1 allele group were included in our PCR-SSP reaction to allow differentiation of homozygous from All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method.

The presence of amplified DNA fragment is a positive indication of the existence of allele specific sequence in the genomic DNA. Abstract. 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 allelic (high resolution) typing results.

This method, the single specific primer-PCR (SSP-PCR), permits amplification of genes for which only a partial sequence information is available, and allows unidirectional genome walking from known into unknown regions of the chromosome. Basic features, such as throughput and resolution of the methods, have been outlined.

All reagents but the Taq Poly- merase were pre-mixed and stored at -20°C in order to speed the process of typing. Polymerase chain reaction with sequence specific primers (PCR-SSP) is the most frequently adapted molecular method used for the recognition of HLA-B*27-specific DNA sequences.

2019-01-01 · Considering the advantages and disadvantages of each method available for the detection of erythrocyte antigens and aiming at the minimization of costs and the agility of the reports produced without the loss of the safety procedure, the objective of this study was to compare the centrifugation hemagglutination gel test, PCR-RFLP, Microarray and PCR-SSP techniques, regarding the cost, reaction The advantages of Ampdirect combined with the PCR-SSP method are not only to develop faster DNA typing procedure but also to reduce the chance to mix up samples by careless mistake, and further to Methods: Primers for each DQA1 and DQB1 allele group were included in our PCR-SSP reaction to allow differentiation of homozygous from heterozygous carriers of risk alleles. Primers detecting the tightly linked DRB1*04, *03, *07 and *09 alleles were included to resolve potentially ambiguous results. Se hela listan på academic.oup.com Die SSP-Methode nutzt Allel-spezifische Primer in der PCR zur Typisierung. Die Methode beruht auf dem Prinzip, dass nur Primer, deren Sequenzen vollständig komplementär zur Zielsequenz einer vorliegenden DNA-Probe sind, an diese DNA binden und in einer PCR-Reaktion ein Amplifikat erzeugen. Eine sehr genaue Unterscheidung der größtenteils sehr ähnlichen HLA-Strukturen ist mit Hilfe der SSP-Methode möglich. Here, we report sequence‐specific priming‐polymerase chain reaction (SSP‐PCR) methods for the detection of HLA‐A*29 and HLA‐B*51 using a single PCR reaction per allele. The assays were tested in 30 and 32 previously HLA‐typed samples, respectively, representing >97% of HLA‐A alleles and >93% of HLA‐B alleles in a European population.
