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.
KitAlysis High-Throughput Screening Kits provide solution to efficiently identify or optimize suitable catalytic reaction conditions. Chemist can rapidly run 24 unique micro scale reactions in parallel with tailored conditions.
Two metabolic pathways exist for the biosynthesis of isopentenyl pyrophosphate and dimethylallyl pyrophosphate: The mevalonate pathway, predominantly used by plants and in a few insect species. The non-mevalonate pathway or methyl D-erythritol 4-phosphate (MEP) pathway, which occurs in plant chloroplasts
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.
A significantly improved HPLC-fluorescence method for DMB-NANA and -NGNA, and application of this method to compare 2 candidate biosimilar therapeutic proteins to their respective RMs.
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.
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
Learn how multiplex detection of Alzheimer’s disease biomarkers, using the MILLIPLEX®Human Amyloid Beta and Tau Magnetic Bead Panel, allows for a different perspective on neurodegenerative disease research.
The signal ratio of two different protons can be measured with tremendous precision, which enables the generation of certified reference materials for use as qNMR standards.
Learn about the five main classes of lipoproteins: chylomicrons, very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), low density lipoproteins (LDL) and lipoprotein(a), and high density lipoproteins.
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.
Mature microRNAs (miRNAs) are a class of naturally occurring, small non-coding RNA molecules, about 21-25 nucleotides in length. MicroRNAs are partially complementary to one or more messenger RNA (mRNA) molecules, and their main function is to downregulate gene expression
This page covers the use of Sepharose High Performance media for purification of proteins, peptides or oligonucleotides, when to use them, and with which systems.
Due to the adverse impact of the continued use of fossil fuels on the earth’s environment and climate, researchers have been asked to develop new approaches for producing power using renewable sources like wind and solar energy
Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
