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.
Myokine analysis with multiplex immunoassays, such as the MILLIPLEX® Human Myokine Panel, allow researchers to simultaneously measure multiple muscle-secreted factors, providing more insights into related diseases.
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
The Novabiochem® product line has one of the most extensive ranges of polymer-supports for solid phase peptide synthesis. They range from high-loaded, lows welling for the large-scale production of relatively short peptides to high-swelling, low-loaded for the synthesis of long
1 Introduction of a guanidinyl group can be achieved by the reaction of substituted amines with various guanylation reagents.2,3,4 One such guanylating reagent is bis(tert-butoxycarbonyl)thiopseudourea, polymer-bound.
Reliable identification and quantification of unknown extractables of a single-use system (SUS) with a 21 component CRM mix for liquid chromatography (LC-UV/MS) methods using Ascentis® C18 column.
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.
Samples for chromatographic purification should be clear and free from particulate matter. Simple steps to clarify a sample before beginning purification will avoid clogging the column, can reduce the need for stringent washing procedures, and can extend the life of
Use the calculator to determine the boiling point or pressure of solvents based on the Antoine Equation and see solvent attributes. View a list of products based on the solvent CAS number.
Selenium is an essential trace element. It is a necessary dietary constituent of at least 25 human selenoproteins and enzymes containing selenocysteine. Additionally, as selenium is a semiconductor and photoelectrically active, it has more advanced applications such as xerography and
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
Ionic Liquids have experienced a comet-like boost in the last few years. In this edition of ChemFiles, we highlight some current applications of this fascinating class of new materials. We present over 50 new additions to our portfolio of 130+
Check the solubility of 128 common inorganic compounds (salts and acids) in water at different temperatures from 0 degrees Celsius to 100 C. Compound formulas are also given in this table of solubility in relation to temperature.
Silica is a very popular inorganic nanomaterial used in a wide range of applications including fillers for rubber, catalyst supports, separation media, carriers in food and agriculture, and abrasive/anticaking agents in cosmetics. It is also widely believed to be an
Magnetic materials permeate numerous daily activities in our lives. They are essential components of a diversity of products including hard drives that reliably store information on our computers, decorative magnets that keep the shopping list attached to the refrigerator door
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.
Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.
Colorectal cancer is the third most common cancer in both men and women. An estimated 136,000 cases of colorectal cancer are expected to occur in 2016.
Highlighting new synthetic modifications of PEG to improve the mechanical properties and degradation of resulting hydrogels in tissue engineering applications.
