A LIBS microscope combines visual and qualitative chemical inspection in a single work step allowing you to save 90% of your time to determine microstructure composition compared to inspection with conventional SEM/EDS. Integrated Laser Induced Breakdown Spectroscopy (LIBS) delivers the exact chemical fingerprint of the material’s structure that you see in the microscope image - within seconds.

The Cytek® Aurora offers unprecedented assay flexibility and panel complexity thanks to our unique, full-spectrum optical design. With up to 5 lasers and 64 fluorescent detectors, the Cytek® Aurora can capture the entire emission spectrum from each fluorochrome. This makes it possible to now run 40 colors in one tube, a first for 40 fluorescence-based flow cytometry.

Whole IgG antibodies are isolated as intact molecules from antisera by affinity chromatography.

Normal serum can be used as a blocking agent to reduce background. Normal serums are lipid extracted to improve clarity, dialyzed against phosphate buffered saline (PBS) containing sodium azide, and freeze-dried. Normal serum diluted to 5% (v/v) in PBS is strongly recommended as a blocking agent to reduce background from non-specific, conserved-sequence, and/or Fc-receptor binding. Best results are obtained with diluted nor…

Using biotinylated secondary antibodies along with conjugated streptavidin is a robust means of signal amplification. Conjugates of streptavidin are recommended for use with Biotin-SP-conjugated affinity-purified secondary antibodies and Biotin-SP-conjugated ChromPure proteins. We offer a comprehensive list of fluorophores and enzymes conjugated to streptavidin for use in enzyme immunoassays, immunohistochemistry, flow c…

The 1515 Isocratic HPLC Pump is an isocratic pump that offers the same performance as the 1525 Binary HPLC Pump. It features and integrated, high-pressure binary pump with on-board pulse dampening and efficient mixing. Its pulse-free solvent flow with analytical to semi-preparative flow rates are well suited for high sensitivity detectors Designed for use with 2 to 4.6 mm I.D. columns in routine HPLC applications, the pump has…

The patented RapiGest™ SF Surfactant is a reagent used to enhance enzymatic digestion of proteins, both in-gel and in-solution. RapiGest SF helps solubilize proteins, making them more susceptible to enzymatic cleavage without inhibiting enzyme activity.Unlike other commonly used denaturants, such as SDS or urea, RapiGest SF does not modify peptides or suppress protease activity. It is compatible with enzymes such as Trypsin,…

Protein/Peptide Columns

LC/GC Certified vials are tested by LC/UV for residues of chemicals used in processing and packaging vials. The septa are tested by headspace GC to ensure low levels of low molecular weight polymer. These vials are suited for analyte concentration in the µg/mL concentration; typically detectors like UV and RI.

Most chromatographers have experienced problems retaining and separating polar compounds using conventional reversed-phase chromatography.  These difficult-to-analyze compounds either pass through the column unretained or, if retained at all, co-elute at the beginning of the chromatogram.  Waters AtlantisTM columns are designed for these types of challenging separations and are available in two chemistries: dC18 and HILIC sili…
