Optimization of a Reversed-Phase Liquid Chromatographic (RP-LC) method for the intact analysis of a therapeutic monoclonal antibody, trastuzumab, using a BIOshell™ A400 Protein C4 column.
Quantitative PCR (qPCR) and qRT-PCR reagents and kits that are designed to deliver maximum efficiency and reliable results from a variety of genetic materials.
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.
High-throughput qPCR using SYBR® Green is a demanding application that requires consistent and reproducible results from low-volume, high-speed assays.
This application note describes the LC-MS-based quantitative analysis of known nitrosamine impurities following procedures 1 and 3 as given in USP general chapter .
Polyethylene glycol (PEG) reagents offer numerous favorable characteristics, including high water solubility, high mobility in solution, lack of toxicity and immunogenicity, and ready clearance from the body.
Asymmetric hydrogenation reactions represent the ideal process for the commercial manufacture of single-enantiomer compounds, because of the ease by which these robust procedures can be scaled up and because of the low levels of byproducts generated in these asymmetric hydrogenations.
HILIC mode chromatography using an Ascentis® Express OH5 resolved the majority of the acyl-L-carnitines tested. It may be possible to use MS/MS and particular fragment ions to resolve the two coeluting pairs.
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.
We are proud to offer the isothiourea organocatalyst homobenzotetramisole (HBTM) as part of our asymmetric catalysis portfolio in both (R) and (S) enantiomeric forms.
High sensitivity multiplex panels allow researchers to detect low-level cytokines and study multiple cytokines at once to dive deeper into low-level inflammation processes. See a performance comparison of the 384-well assay and the 96-well assay formats for the MILLIPLEX® Human
Data was compiled to assist the researcher in selecting references most likely to contain relevant information regarding use of Percoll for a particular cell or tissue type.
