background and objectives : dna molecular weight marker is widely used in molecular biology experiments incurring considerable costs on low-budget settings. materials and methods : here a pcr-supported procedure is described that uses 10 primer pairs targeting chromosomal dna from the harmless vaccinal bacillus anthracis sterne 34f2 strain as template. a single pcr protocol is used to reproduce...
DNA size markers are widely used to estimate the size of DNA samples on agarose or polyacrylamide gelelectrophoresis (PAGE). DNA markers can be prepared by mixing PCR products with definite sizes.Alternatively, they are prepared by restriction enzyme digestion of the genomic DNA of bacteriophages ornatural and synthetic DNA plasmids. The present study describes engineering of ...
samples from five sturgeon species including persian sturgeon (acipenser persicus), russian sturgeon (a. gueldenstaedti), great sturgeon (huso huso),ship sturgeon (a. nudi-ventris) and stellate sturgeon (a. stellatus) were collected from the south caspian sea. dna was extracted from the fins, eggs and skeleton muscle of the five species. rapd markers were used for identifying different kinds of...
DNA size markers (ladder) are essential tools in molecular biology, genetics and biotechnology. In this study, a simple and cost-effective method for laboratory production of DNA ladders is introduced. For this purpose, different sizes of 100 to 2000 bp DNA segments were designed using PCR technique. For producing 14 different gene fragments as DNA molecular weight markers, recombinant plasmid ...
objective: dna markers are one of the most important indicators for estimating molecular weight of dna samples, although it used in widespread medical and research laboratories. these markers are very divers and have been prepared in different manners and from different sources of dna. but unfortunately, dna markers haven't been made in our country and all of the markers that we use are made in...
Background and Objective: The association of EBV with Hodgkin Lymphoma (HL) has been intensely investigated over the last few years. EBV is also associated with several other malignancies. On the other hand, Ki67 molecule serves as a widely accepted proliferation marker. Several studies were previously p...
Grapevine (Vitis vinifera L.) is one of important economic fruit crops found in Salahaldin province \ Iraq. To examine the Molecular characterization and genetic relationships among nine grape varieties by using random amplified polymorphic DNA (RAPD) marker. Fifteen RAPD primers produced band (71, 56%), while two yielded monomorphic bands only. The size fragment ranged between 250-2700 bp, wit...
Background: Indirect genetic diagnosis using polymorphic DNA markers can detect carriers of hemophilia A. This technique is preferable in developing countries because of its simplicity and cost effectiveness compared to direct mutation analysis. In the present study, we examined usefulness of intragenic marker BclI restriction fragment length polymorphism (RFLP) at intron 18, for carrier detect...
DNA molecular weight standard control, also called DNA marker (ladder), has been widely used in the experiments of molecular biology. In the paper, we report a method by which DNA marker was prepared based on multiple PCR technique. 100-1000 bp DNA fragments were amplified using the primers designed according to the 6631 ~ 7630 position of lambda DNA. Target DNA fragments were amplified using T...
G-protein-coupled receptor (GPR54) is one of the known gene affecting fecundity. This gene affects the ovulation rate and litter size performance. A total of 160 animals including Sanjabi (n=100) and Ghezel (n=60) were used to identify polymorphisms of GPR54 gene and their influence on litter size. Genomic DNA was extracted by commercial DNA kit. The genotypic patterns were detected using th...
