Lipopolysaccharides (LPS) are characteristic components of the cell wall of Gram negative bacteria; they are not found in Gram positive bacteria. They are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell
Potency testing in marijuana-infused edibles is an important problem that analytical labs are facing due to the complexity of the involved matrices. Concentration of active ingredients in these edibles can range from a few parts per million to 3.5 parts
Ligand used to prepare a palladium dichloride catalyst on treatment with PdCl2(COD). The catalyst effectively cross-couples aryl boronic acids with heteroaryl chlorides.
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.

Multiplex like never before with the MILLIPLEX® Non-Human Primate Cytokine/Chemokine/Growth Factor Panel A that offers researchers the ability to profile the largest selection of immune factors available for non-human primates on one 96-well plate.
Supel Tox AflaZea SPE produced exceptional analyte recoveries with good reproducibility for all aflatoxins while requiring less than half the sample volume required by competing products.HPLC analysis of all spiked samples after SPE cleanup showed that all compared SPE cartridges
The table was compiled to assist the researcher in selecting references most likely to contain relevant information regarding use of Percoll in various cell types.
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
Proline analogues are promising candidates for tuning the biological, pharmaceutical, or physicochemical properties of naturally occuring, as well as de novo designed, linear, and, cyclic peptides.
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.
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
Research evaluating immune checkpoints may help identify those likely to benefit from PD-1/PD-L1 immunotherapy and reveal new immunotherapy targets for future investigation. See how the MILLIPLEX® Human Immuno-Oncology Checkpoint Protein Panel 2 was used to multiplex immune checkpoint molecules for
Tissue engineering has become a key therapeutic tool in the treatment of damaged or diseased organs and tissues, such as blood vessels and urinary bladders.
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
