Upgrading SELEX Technology by Using Lambda Exonuclease Digestion for Single-Stranded DNA Generation
Molecules, 2009 The generation of single-stranded DNA (ssDNA) molecules plays a key role in the SELEX (Systematic Evolution of Ligands by EXponential enrichment) combinatorial chemistry process and numerous molecular biology techniques and applications, such as DNA ...

Elasticity of strongly stretched ssDNA [PDF]
Physica A: Statistical Mechanics and its Applications, 2007 We present a simple model which describes elastic response of single-stranded DNA (ssDNA) to stretching, including the regime of very high force (up to 1000 pN). ssDNA is modelled as a discreet persistent chain, whose ground state is a zigzag rather than a straight line configuration.

DNA Nanoarray for Multiplexed RNA Detection With Single‐Molecule Readout
Advanced Science, EarlyView.A carrier‐based DNA nanoarray integrates programmable nucleic acid hybridization with solid‐state nanopore readout for direct RNA detection at single‐molecule resolution. A ternary encoding system enables 27 carriers with 81 addressable sensing sites, allowing the simultaneous identification of targets spanning a wide size range, from short microRNAs ...

Recombination in Eukaryotic Single Stranded DNA Viruses
Viruses, 2011 Although single stranded (ss) DNA viruses that infect humans and their domesticated animals do not generally cause major diseases, the arthropod borne ssDNA viruses of plants do, and as a result seriously constrain food production in most temperate ...

A Phage Single-Stranded DNA (ssDNA) Binding Protein Complements ssDNA Accumulation of a Geminivirus and Interferes with Viral Movement [PDF]
Journal of Virology, 1999 ABSTRACT Geminiviruses are plant viruses with circular single-stranded DNA (ssDNA) genomes encapsidated in double icosahedral particles. Tomato leaf curl geminivirus (ToLCV) requires coat protein (CP) for the accumulation of ssDNA in protoplasts and in plants but not for systemic infection and symptom development in plants.

Optimization of SWCNT‐FET Biosensors by Aptamer Engineering and Toehold‐Mediated Strand Displacement
Advanced Science, EarlyView.Aptamer‐based single‐walled carbon nanotube (SWCNT) field‐effect transistor (FET) biosensors are developed for label‐free, real‐time biomarker detection. Truncated DNA aptamers enhance sensitivity through improved conformational switching. A toehold‐mediated strand displacement (TMSD) strategy optimizes functionalization and simplifies fabrication. The

Advanced Science, EarlyView.ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

Advanced Science, EarlyView.The aptamer WHY‐3E identifies PrPC as a CRC driver. Stabilized by USP18, endocytosed PrPC forms a LYN/STAT3 complex, upregulating MSN transcription to promote metastasis. Crucially, WHY‐3E sensitively detects PrPC‐positive circulating exosomes, establishing a robust theoretical foundation for non‐invasive clinical diagnostics.
