Quinaldine Red as a fluorescent probe for determining the melting temperature () of proteins: a simple, rapid and high-throughput assay.

Proteins play an important role in biological systems and several proteins are used in diagnosis, therapy, food industry Thus, knowledge about the physical properties of the proteins is of utmost importance, which will aid in understanding their function and subsequent applications. The melting temperature () of a protein is one of the essential parameters which gives information about the stability of a protein under different conditions. In the present study, we have demonstrated a method for determining the of proteins using the supramolecular interaction between Quinaldine Red (QR) and proteins.

A phenol-chloroform free method for cfDNA isolation from cell conditioned media: development, optimization and comparative analysis.

The non-invasive invasive nature of cell-free DNA (cfDNA) as diagnostic, prognostic, and theragnostic biomarkers has gained immense popularity in recent years. The clinical utility of cfDNA biomarkers may depend on understanding their origin and biological significance. Apoptosis, necrosis, and/or active release are possible mechanisms of cellular DNA release into the cell-free milieu.

Biochemical characterization of clinically relevant mutations of human Translin.

DNA damage in all living cells is repaired with very high efficiency and nucleic acid binding proteins play crucial roles in repair associated processes. Translin is one such evolutionarily conserved nucleic acid interacting protein speculated to be a part of the DNA repair protein network. It is also involved in activation of RNA-induced silencing complex (RISC) along with Translin-associated factor X (TRAX) as the C3PO (component 3 promoter of RISC) complex.

An improved, simple and field-deployable CRISPR-Cas12a assay for the detection of SARS-CoV-2.

Aims: The RT-PCR is the most popular confirmatory test for SARS-CoV-2. It is sensitive, but high instrumentation cost makes it difficult for use outside routine clinical setup. This has necessitated the development of alternative methods such as CRISPR-based DETECTR method which uses lateral flow technology.

Cold Plasma: Clean Technology to Destroy Pathogenic Micro-organisms.

Atmospheric pressure cold plasma is a promising technology in fighting pathogenic micro-organisms. In times of Covid-19 pandemic, it was decided to modify two types of cold plasma devices to study their effectiveness in the killing of pathogenic micro-organisms. These studies have shown that both the devices are efficient in this purpose.

A miniaturized electrochemical platform with an integrated PDMS reservoir for label-free DNA hybridization detection using nanostructured Au electrodes.

We report the fabrication and characterization of a miniaturized electrochemical platform for the label-free detection of DNA hybridization. The proposed platform is fabricated using microfabrication and electrodeposition techniques. Comprising a Ti working electrode with electrodeposited Au nanostructures, and Pt/Au pseudo-reference and counter electrodes, the device accounts for a limit of detection of 0.

Development of low-density oligonucleotide microarrays for detecting mutations causing Wilson's disease.

Background & Objectives: Wilson's disease (WD) is an autosomal recessive disorder caused by mutations in ATP7B, a copper transporter gene, leading to hepatic and neuropsychiatric manifestations due to copper accumulation. If diagnosed early, WD patients can be managed by medicines reducing morbidity and mortality. Diagnosis of this disease requires a combination of tests and at times is inconclusive due to overlap of the symptoms with other disorders.
