Denaturing high-performance liquid chromatography (DHPLC) is an accurate and efficient screening technique used for detecting deoxyribonucleic acid sequence changes by heteroduplex analysis. It can also be used for genotyping of single-nucleotide polymorphisms. The high-sensitivity of DHPLC has made this technique one of the most reliable approaches to mutation analysis and is used in various areas of genetics, both in the research and clinical arena. This chapter describes the methods used for mutation detection analysis and the genotyping of single-nucleotide polymorphisms by DHPLC on the WAVETM system from Transgenomic Inc.

This review describes mass spectrometry (MS)-based approaches for the absolute quantification of therapeutic monoclonal antibodies (mAbs), focusing on technical challenges in sample treatment and calibration. Therapeutic mAbs are crucial for treating cancer and inflammatory, infectious, and autoimmune diseases. We trace their development from hybridoma technology and the first murine mAbs in 1975 to today's chimeric and fully human mAbs.

Bovine serum albumin (BSA) plays a crucial role as a carrier protein in plasma, binding various ligands, including drugs. Understanding the interaction between BSA and saquinavir, an antiretroviral drug, is essential for predicting its pharmacokinetics and pharmacodynamics. We employed spectroscopic approaches, including circular dichroism spectrometry and fluorescence spectroscopy, to investigate the binding of saquinavir to BSA.

Functional nanomaterials with enzyme-mimicking activities, termed as nanozymes, have found wide applications in various fields. However, the deviation between the working and optimal pHs of nanozymes has been limiting their practical applications. Here we develop a strategy to modulate the microenvironmental pHs of metal-organic framework (MOF) nanozymes by confining polyacids or polybases (serving as Brønsted acids or bases).

Objective: To explore the protective effect and mechanism of acetate on sepsis-induced acute kidney injury (AKI) in rats.
Methods: Male Sprague-Dawley (SD) rats were divided into sham operation group (Sham group), sepsis group caused by cecal ligation and puncture (CLP group), and acetate pretreatment group [NaA group, gavage sodium acetate (NaA) 300 mg/kg twice a day for 7 consecutive days before CLP] using a random number table method, with 7 rats in each group. The blood was taken from the main abdominal artery 24 hours after modeling, and renal tissue was collected from the rats.
A Novel Platform Featuring Nanomagnetic Ligand Fishing Based on Fixed-Orientation Immobilized Magnetic Beads for Screening Potential Cyclooxygenase-2 Inhibitors from Leaves.

A novel screening platform based on an FeO@C@PDA-Ni@COX-2 ligand fishing combination with high-performance liquid chromatography-mass spectrometry was first designed, synthesized, and employed to screen and identify COX-2 inhibitors from leaves. The obtained magnetic nanoparticles exhibit outstanding preconcentration ability that allows for controlling the enzyme orientation to avoid enzyme active site blocking, conformational changes, or denaturing during immobilization. The as-prepared FeO@C@PDA-Ni@COX-2 composite was carefully characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectrometry (FT-IR), Xray powder diffraction (XRD), thermal gravimetric analyzer (TGA), vibrating sample magnetometer (VSM), and Zeta potential analysis.
