Analysis of Residual Solvents in Hemp Extract by Headspace SPME-GC/MS
The use of solid phase microextraction (SPME) allowed for the straightforward, fast, sensitive, and accurate GC/MS determination of the residual solvent content of spiked and unspiked samples of hemp extract.
Improved Recoveries and Lower Background for GC/MS/MS and LC/MS/MS Analysis of Pesticides in Green Tea
A procedure for cleanup of green tea extracts provides low background and allowed for the analysis of more pesticides at lower levels than QuEChERS. Uses less solvents and no toluene.
SPME-GC-MS Determination of Phthalate Esters in Ramen Noodle Flavor Packets
A sensitive, quantitative, and reproducible SPME-GC/MS procedure was developed by Supelco for the extraction of phthalate esters from oily food matrices, such as the flavored oils included with ramen noodle kits.
Analysis of Pesticide Residues in Pistachios Using QuEChERS Extraction and Cleanup with Supel™ QuE Z-Sep+
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.
Use of PEPscreen® Peptides to Investigate CTL Class I MHC and Th Class II Responses to AAV-hF.IX Gene Therapy
Recombinant adeno-associated virus (AAV)-mediated gene therapy expressing human coagulant factor IX (hF.IX) is a promising gene transfer strategy due to the long-term expression of hF.IX in the liver and weak immune response using a liver-specific promoter. However, in humans and...

The Extraction of Amphetamine and Related Drugs using Molecularly Imprinted Polymer SPE
What is the Extracellular Matrix?
The extracellular matrix (ECM) is secreted by cells and surrounds them in tissues.
Boc Resin Cleavage and Deprotection
The most popular reagent for cleavage of peptides from Boc-based resins is anhydrous HF. Of all the cleavage procedures HF appears to be the most versatile and least harmful to a wide variety of peptides synthesized on Boc-based resins.
Calcium in Cell Culture
Calcium is an ionically stable divalent cation with important beneficial and toxic properties in cell culture. It is a component of a wide range of cell culture media.
2D Materials Matter: A Perspective on Biosensing Applications
Professor Ebrahimi and Professor Robinson (Pennsylvania State University, USA) summarize recent advances in the synthesis of these 2D materials, resulting material properties, and related applications in biosensing of neurotransmitters, metabolites, proteins, nucleic acids, bacterial cells, and heavy metals.
Vitamin B12, Cobalamin, in Cell Culture
Importance and uses of Vitamin B12 in serum-free eukaryotic, including hybridoma and Chinese Hamster Ovary (CHO) cell cultures
Alkyne Hydrosilylation
Vinyl-metal reagents play a pivotal role in organic synthesis. Among the vinyl-metal reagents available, silicon-based reagents are of increasing importance. This is largely due to their low cost, minimal toxicity, ease of handling, and the simplicity of byproduct removal.
