Absolute Quantification (Protein-AQUA™™) is a targeted quantitative proteomics technique that exhibits robust efficacy and is being increasingly utilized for a wide variety of quantitative proteomics studies.
We have developed Certified Reference Materials (CRMs) of fully intact milk proteins that allow accurate testing of the most critical proteins in infant formula; help labs to develop and test infant formula products with high accuracy, while ensuring legal and
Clinical laboratories are beginning to reap the benefits of LC-MS in terms of its sensitivity, specificity, throughput, and potential to reduce cost per sample. The purpose of this study was to demonstrate the LC-MS analysis of Warfarin in plasma samples
Various plastics used as barriers to the production of off-flavors in light exposed milk were examined using HS-SPME with a new Carboxen®/PDMS coated Nitinol fiber followed by GC-MS analysis allowing detection of low MW analytes at levels <1 ng/mL.
Bisphenol A (BPA) plastic is controversial in food and beverage containers. This study demonstrates SPME of BPA from an energy drink using an overcoated PDMS/DVB fiber, followed by GC/MS/MS analysis using SLB-PAHms GC Column.
The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the
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.
Innovative solid phase extraction (SPE) technology from Supelco, utilizes phospholipid retention mechanism based on highly selective interaction between proprietary zirconia ions (bonded to the stationary phase) and the phosphate moiety consistent with phospholipids and proteins.
Cannabis testing regulations include analysis of purity, potency, and contaminants. Learn more about analysis of cannabis for pesticides, mycotoxins, and pyrethrins registered in California by LC-MS/MS and GC-MS/MS Using Ascentis® Express Biphenyl and SLB®-5ms Columns
