Nondestructive DNA extraction method for mitochondrial DNA analyses of museum specimens

Nondestructive DNA extraction method for mitochondrial DNA analyses of museum specimens.

Museum specimens have provided the material for a large proportion of ancient DNA studies conducted during the last 20 years. However, a major drawback of the genetic analyses is that the specimens investigated are usually damaged, as parts of skin, bone, or a tooth have to be removed for DNA extraction. To get around these limitations, we have developed a nondestructive extraction method for b...

DNA Extraction from Museum Specimens of Parasitic Hymenoptera

At the same time that molecular researchers are improving techniques to extract DNA from museum specimens, this increased demand for access to museum specimens has created tension between the need to preserve specimens for maintaining collections and morphological research and the desire to conduct molecular analyses. To address these concerns, we examined the suitability of non-invasive DNA ex...

A REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA

Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...

Enhanced DNA extraction and PCR amplification of mitochondrial genes from formalin-fixed museum specimens.

A RAPID AND SIMPLE METHOD OF DNA EXTRACTION FROM CLINICAL SPECIMENS CONTAINING MYCOBACTERIUM LEPRAE FOR PCR ASSAYS

We describe a rapid, simple, and reliable procedure for routine isolation of Mycobacterium leprae DNA from slit-skin swab specimens. This one-step DNA extraction method is based on the utilization of ChelexR 100, a chelating ion exchange resin. Slit-skin swab specimens from seven untreated leprosy patients at Baba Baghi Leprosy Hospital in Iran were processed by this procedure. The polymer...
