Application Notes: General

Statins were analyzed without using reversed phase mode separation nor ion-pairing reagents.

Shodex RSpak DE-413L is suitable for the analysis of water-soluble vitamins in a single run.

Shodex HILICpak VT-50 is suitable for the analysis of phosphorous-containing amino acids herbicids including glyphosate, glufosinate and their metabolites using ESI-MS detection.

Antibody molecular weight analysis can now be easily performed on the Shodex PROTEIN LW-803.

Essential oils have been a staple of the food, fragrance, and health markets for many years. Owing to their unique composition, essential oils can be used for a variety of applications.

µPAC™ technology has been used for analysing HCP impurities originating from recombinant expression systems used in the production of mAb based biotherapeutics.

This note describes how SEC-MALS-UV-RI analysis quantifies multiple critical quality attributes of AAV viral vectors, including concentration/titer, aggregation and empty:full ratio.

All data is a cGMP record, as regulators enforce requirements to ensure the integrity of laboratory data. Find out how LabVantage Solutions can aid in compliance.

• QuEChERS vs. a modified method with the Geno/Grinder for pesticide analysis • Stable isotope analysis for the testing of food product origins • Arsenic testing in hard ciders

• Characterizing cannabis • Terpenes analysis using headspace solid-phase microextraction and GC–MS • LC triple-quad and GCxGC-TOFMS for efficient cannabis testing.

With Antec Scientific’s new ground-breaking µ-PrepCell-SS, electrochemical reduction of disulfide bonds in peptides, proteins, mAbs, and other biopharmaceuticals becomes possible routinely in LC-MS workflows. • Fast and efficient reduction of S-S bonds • Robust on-line reduction in top-down and bottom-up Proteomics • Reagent free, no interfering DTT or TCEP, ideal for HDXMS • Superior peptide sequencing and S-S bond assignment

An effective enrichment method for glycopeptides were developed based on iSPE®-HILIC material. It opens a range of opportunities for glycoproteomics research.

Testing shows that Restek Long-Life ESI electrodes for Sciex Turbo V sources provide equivalent chromatographic performance to original equipment manufacturer electrodes over significantly longer lifetimes.
