Ovarian cancer BRCA1 mutation detection: Protein truncation test (PTT) outperforms single strand conformation polymorphism analysis (SSCP)

Mutation Detection by Single Strand Conformation Polymorphism and Heteroduplex Analysis

Single strand conformation polymorphism (SSCP) and heteroduplex analysis (HDA) are two of the most popular electrophoresis-based mutation detection methods. Coupled to DNA amplification of the sequence to be analyzed, these techniques have become the methods of choice for a number of molecular diagnostic laboratories. This can be explained mainly by the numerous advantages, namely their technic...

F-SSCP: fluorescence-based polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) analysis.

A fluorescence-based method for polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) analysis, F-SSCP, was developed in which the target sequence is amplified by the PCR using fluorescent primers. The amplified products are then heat-denatured and applied to a water-jacket controlled gel in an automated DNA sequencer. The separated strands are detected as laser-excited f...

جهش های ژنتیکی جدید در ژن های اصلی سرطان پستان (BRCA1/BRCA2) در زنان ایرانی مبتلا به سرطان پستان زودرس

Background: Breast cancer is the most common female malignancy and the main cause of death in  mid-aged women. Genetic germ line mutations in BRCAI/BRCA2 in Iranian women with breast or  ovarian cancer have not been yet reported. Materials and methods: Clinical data, family history and blood samples were obtained from 83  females aged less than 45 years with primary breast cancer in order to su...

Carrier Determination in a Hemophilia B Family Using Single Strand Conformation Polymorphism (SSCP) and Sequencing

non-radioactive single-strand conformation polymorphism (sscp) analysis of relatively long pcr products

the sscp technique is based on the appearance of new “refolding” conformations during electro-phoresis due to mutation. in order to develop a simple, non-radioactive sscp analysis method so that it can reliably detect single nucleotide changes in pcr products up to 500 bp in length, extensive optimisation trials were performed . the best separation of sscp bands of pcr products up to 500 bp in ...
