SYTO9 and SYBR green1 with high resolution melting analysis for molecular confirmatory testing of the common Southeast Asian β0- thalassemia mutations
Gel electrophoresis and ethidium bromide staining are routine methods in molecular laboratories. However, they are not ideally suited to large scale analyses in clinical laboratories. We used SYTO9 and high resolution melting (HRM) analyses for identification of the common β0-thalassemia (β0-thal) i...

Gel electrophoresis and ethidium bromide staining are routine methods in molecular laboratories. However, they are not ideally suited to large scale analyses in clinical laboratories. We used SYTO9 and high resolution melting (HRM) analyses for identification of the common β0-thalassemia (β0-thal) in Southeast Asia including the codons 17 (A>T), 4142 (-TCTT) and 7172 (A) mutations. Multiplex amplification refractory mutation system-polymerase chain reaction (MARMS-PCR) was performed on 102 blood samples that had Hb A2 levels between 3.1 and 9.9. The SYTO9 HRM analysis showed specific characteristic peaks of each investigated type of β0- thal mutation. Results of MARMS-PCR followed by SYTO9 HRM analyses were completely consistent with results of those analyzed by gel electrophoresis. Moreover, the β0-thal 3.5 kb gene deletion could be identified in two samples with Hb A2 levels of >4 by GREEN1 HRM analysis. The SYTO9 and SYBR GREEN1 HRM analysis is simple and rapid.
