Studies on the Preparation of a Novel Supermix Dna Ladder by Restriction Digestion
نویسنده
چکیده
Modern biological tools of recombinant technology have tremendous potential to characterize DNA molecules with the choice of DNA ladders. Determination of molecular weight of linear and double stranded DNA fragments either on agarose or polyacrylamide gel is done extensively with the DNA ladders. The most popular DNA ladders available in the market range from less than 25bp to 40 kb or more. Amalgamation of predetermined or definite size Polymerase Chain Reaction products to achieve novel DNA marker is the most common practice. In this study, we have described a method by which two novel supermix DNA ladders were prepared based on restriction digestion. The strategy was based on single, double and triple restriction digestion of plasmid and genomic DNA from various sources. The samples were run on 1% agarose gel, and the obtained pattern was analysed against available commercial ladders. The supermix DNA ladder constructed can be used in laboratory for analytical and diagnostic purposes in the field of molecular biology.

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 ...

Background: Molecular DNA markers are one of the most important tools in molecular biology labs. The size of DNA molecules is determined by comparing them with known bands of markers during gel electrophoresis. There are many different protocols to produce these kinds of molecular markers. In this study we have suggested an efficient strategy to produce molecular weight markers in industrial pr...

Background: Aspergillus species are occasionally associated with human infections. It is essential to find a rapid and reliable method to identify these fungi and can be useful for screening the disease and also epidemiological aims. Materials and Methods: Our subjects included Aspergillus species isolated from clinical and environmental sources of four Iranian educational hospitals. Aspergilli...

In an extensive analysis, using a range of restriction endonucleases, HinfI and TaqI were found to differentiate satellites I, II and III & IV. Satellite I is resistant to digestion by TaqI, but is cleaved by HinfI to yield three major fragments of approximate size 770, 850 and 950bp, associated in a single length of DNA. The 770bp fragment contains recognition sites for a number of other enzym...

Background and aim: Dermatophytosis (tinea, ringworm) is the infection of skin, hair or nail that is caused by various keratinophilic fungi (dermatophytes). Dermatophytosis is a common infection throughout the world including all parts of Iran. As conventional laboratory procedures for identification of different dermatophytes are slow or lack specificity, more rapid and reliable methods are st...
