Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
A simplified LC-MS/MS method to determine glyphosate and related compounds using a Supel™ Carbon LC U/HPLC column for stability under higher pH conditions and sufficient retention for the polar analytes in the presence of methanol as an extraction solvent.
Exploring genotoxicity and DNA damage through multiplexing with MILLIPLEX® multiplex genotoxicity assays using Luminex® xMAP® technology enables the high-throughput measurement of phosphorylation levels of multiple proteins simultaneously and reduces sample volume, time, and cost.
Silica monoliths with larger mesopores are a powerful tool for the fast separation of biomolecules including mAbs. The immobilization of protein A on epoxy-modified widepore (WP) silica rods enabled highly reproducible and fast, one minute, separations of mAbs. The Chromolith®
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer
Mesoporous silica with uniform and tailorable pore dimensions with high surface areas are used many applications such as wastewater remediation, indoor air cleaning, catalysis, bio-catalysis, and drug delivery.
Learn about the history of the polymerase chain reaction (PCR), from the basic principles that proceeded its discovery to the awarding of a Nobel Prize for Chemistry and more recent developments such as real-time PCR (qPCR) and digital PCR.
In many technologies, performance requirements drive device dimensions below the scale of electron mean free paths (λe). This trend has increased scientific interest and technological importance of electrical resistivities at the nanoscale.
Native DPPIV is a ubiquitous type II transmembrane glycoprotein and a serine protease of the S9 prolyl-oligopeptidase family. In vivo, it is synthesized with a signal peptide which functions as the membrane anchoring domain.
A comprehensive workflow for the analysis of 12 heavy metals, including the “big four”, in five hemp containing food samples by inductively coupled plasma-mass spectrometry (ICP-MS) utilizing the standard addition calibration method.
Lipopolysaccharides (LPS) are characteristic components of the cell wall of Gram negative bacteria; they are not found in Gram positive bacteria. They are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell
Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to
Immunohistochemistry (IHC) techniques and applications have greatly improved, dermatopathology is still largely based on H&E stained slides.This paper outlines ways in which IHC antibodies can be utilized for dermatopathology.
