Development and validation of an HPLC-UV method for purity determination of DNA

Medicine Science, 2023
Determination of the concentration and the purity of DNAs is crucial for measuring the DNA copy number since it will influence further DNA analysis such as digital PCR (dPCR) and next-generation sequencing (NGS).

New HPLC method for determination of fluvastatin anti-hyperlipidemic drug in bulk and pharmaceutical dosage using simvastatin as internal standard

Drug Analytical Research, 2023
A new, and reliable RP–HPLC method has been investigated and validated for the assay of fluvastatin sodium (FVS) in pharmaceutical capsules. The chromatographic method was carried out using an ODS Hypersil C18 column (250×4.6 mm i.d., 5 µm particle size)

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
