New insights on single-stranded versus double-stranded DNA library preparation for ancient DNA.
An innovative single-stranded DNA (ssDNA) library preparation method has sparked great interest among ancient DNA (aDNA) researchers, especially after reports of endogenous DNA content increases >20-fold in some samples. To investigate the behavior of this method, we generated ssDNA and conventional double-stranded DNA (dsDNA) libraries from 23 ancient and historic plant and animal specimens. W...
متن کاملIntroducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA
Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...
متن کاملSingle-stranded DNA library preparation from highly degraded DNA using T4 DNA ligase
DNA library preparation for high-throughput sequencing of genomic DNA usually involves ligation of adapters to double-stranded DNA fragments. However, for highly degraded DNA, especially ancient DNA, library preparation has been found to be more efficient if each of the two DNA strands are converted into library molecules separately. We present a new method for single-stranded library preparati...
متن کاملChallenges to Design and Develop of DNA Aptamers for Protein Targets. I. Optimization of Asymmetric PCR for Generation of a Single Stranded DNA Library
Aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as SELEX. In the amplification and regeneration step of SELEX technique, dsDNA is conversed to ssDNA. Asymmetric PCR is one of the methods used for the generation of ssDNA. The purpose of this study was to design a random DNA library for selection of aptamers wit...
متن کاملPreparation of single-stranded phagemid DNA without chromosomal DNA contamination.
During the culture of phagemidcontaining bacteria infected with M13KO7 helper phage, many host strains such as JM109 and XL1-Blue release their chromosomal DNA into the medium because of lysis of bacteria. This results in chromosomal DNA contamination of the preparation of single-stranded DNA (ssDNA) (2,5). A certain strain of E. coli, DH11S, has been engineered to overcome this problem (2). Ho...
