We develop a strategy for haplotype analysis of PCR products that contained two adjacent heterozygous loci using sequencing with specific primers, allele-specific primers, and ddNTP-blocked primers. To validate its feasibility, two sets of PCR products, including two adjacent heterozygous SNPs, UGT1A1⁎6 (rs4148323) and UGT1A1⁎28 (rs8175347), and two adjacent heterozygous SNPs, K1637K (rs1117601...

genetic diversity of 36 genotypes of dwarf and semi-dwarf apple rootstocks along with seven iranian dwarf rootstocks were investigated by use of rapd dna markers. a set of 100 random primers was utilized in pcr reaction from which 10 primers resulted in good amplification with high polymorphism. among primers, 10 selected rapd primers produced 160 bands, in which, 136 were polymorphic. cluster ...

introduction: htlv-1 , the first known human retrovirus belongs to oncovirus subfamily of retroviruses. the major characteristic of htlv-1 is its highly restricted geographic prevalence. northern part of khorasan is an endemic region of htlv-1 infection. epidemiological studies can help in designing preventive programs for htlv-1 infection. the aim of this study was the establishment of a pcr t...

abstract- desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. a pcr-based method was developed for the identification of 3 major desert truffles of iran: terfezia claveryi, tirmania pinoyi and tirmania nivea based on internal transcribed spacers of rdna. two specific pcr primers were designed for t. claveryi, 4 for t. pinoyi, and 2 for ...

RAPD is a simple dominant marker system widely used in biology. Effectiveness of RAPD can be improved by selecting and redesigning primers whose priming sites occur in target sequence(s) of gene or organism at optimum distance. We developed software that uses sequences of random decamer primers and nucleotide sequence(s) as two input files. It locates the priming sites in input sequences and ge...

Studies have been carried out on the use of octamer oligonucleotides tailed with different base analogues as primers in cycle sequencing reactions. 5-Nitroindole tails improved the performance as primers of a number of octamers. A tail length of three or four 5-nitroindole residues significantly increased the sequencing signal intensity for almost all primers. The use of incomplete libraries of...
