The Quick Western Kit provides a universal detection reagent that can be combined with the primary antibody incubation step, eliminating the need for a secondary antibody incubation step.

IRDye 680RD is the near-infrared fluorescent dye of choice for applications in the 700 nm wavelength, especially Western blots, cell-based assays such as the In-Cell Western assay, and small animal imaging experiments.

IRDye QC-1 is the first non-fluorescent (dark) quencher, compatible with a wide range of visible and near-infrared fluorophores (~500 – 800 nm).

IRDye® Click Chemistry reagents (DBCO, Alkyne, and Azide) offer convenient, versatile and reliable methods for biomolecule labeling. With a variety of in vitro and in vivo applications, from biomarker isolation to assay development.

IRDye Infrared Dyes and near-infrared (NIR) fluorescent imaging deliver enhanced sensitivity due to low background autofluorescence in the near-infrared region, therefore, giving a higher signal to noise ratios.

IRDye Labeling Kits come in 3 forms and allow you to label your own peptides, antibodies, or proteins.

IRDye 800CW secondary antibodies are the antibodies of choice for a wide variety of applications in the 800 channel of Odyssey ® Imaging Systems.

IRDye 680LT dye is highly soluble in water and is significantly brighter and more photostable than many other 700 nm near-infrared dyes.

SupraSolv ® solvents are developed specially for sample preparation in gas chromatography. Ideally suited for all GC applications including sensitive detection tasks in residue and environmental analysis, SupraSolv ® solvents offer you the security and reliability needed for today’s gas chromatography applications.

Indispensable for NMR spectroscopy Unlocking the molecular structure of organic molecules is central to understanding how they interact with other molecules. This is especially critical in genomics, proteomics and drug discovery research. The Nuclear Magnetic Resonance (NMR) technique allows scientists to “see” molecular structure and dynamics. MagniSolv™ deuterated solvents are a key tool for the NMR technique. MagniSolv™ deu…

Containers Make Sense EMD Millipore ReCycler™ Containers guarantee solvent purity and meet the needs of the scientific community by eliminating the need to dispose of large volumes of glass bottles, styrofoam packaging inserts and corrugated cartons. Today, EMD Millipore ReCycler™ containers are available in sizes from 18.9L (5 gallon) to 1250L for the many diverse scientific applications from laboratory to small-scale manufac…

SiliCycle is a pioneer in metal and organic scavenging solutions. We have nearly two decades of know-how in silica-grafting and scavenging technologies, and the broadest portfolio of scavengers.The removal of post-reaction residues has become a major issue in the pharmaceutical industry, among others. Purification of APIs by traditional methods (chromatography, activated carbon, distillation, etc.) often leads to problems such…

Corning® PuraMatrix™ Peptide Hydrogel is a synthetic matrix used to create defined three dimensional (3D) micro-environments for a variety of cell culture experiments. To achieve optimal cell growth and differentiation, it is necessary to determine the appropriate mixture of this material and bioactive molecules (e.g., growth factors, extracellular matrix (ECM) proteins, and/or other molecules). Corning PuraMatrix Peptide Hydr…
