Summary
This study introduces DNA and RNA oligonucleotides as reference standards for measuring biomolecular interactions. These standards facilitate data comparison and instrument calibration across various experimental techniques.
Area of Science:
- Biochemistry and Molecular Biology
- Biophysical Chemistry
Background:
- Accurate measurement of biomolecular interactions is crucial for research and pharmaceutical development.
- Comparing data across different techniques and laboratories can be challenging due to variability.
Purpose of the Study:
- To evaluate complementary DNA and RNA oligonucleotides as reference standards for biomolecular interaction studies.
- To establish a reliable method for validating and comparing experimental data.
Main Methods:
- Thermodynamic analysis of duplex formation using complementary DNA and RNA.
- Isothermal titration calorimetry (ITC)
- Differential scanning calorimetry (DSC)
- UV-visible (UV-vis) monitored denaturation/renaturation.
Main Results:
- DNA and RNA oligonucleotides demonstrate potential as reference standards for biomolecular interactions.
- Established methods for thermodynamic characterization of duplex formation.
Conclusions:
- These oligonucleotide standards offer a cost-effective, high-purity solution for validating experimental results.
- They can serve as teaching tools and aid in instrument calibration for biophysical measurements.

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

02:54Evolutionary Relationships through Genome Comparisons
5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

17.0K
Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

02:26Comparing Copy Number Variations and SNPs
11.4K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

11.5K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...
