The filter wheels can fit to either the excitation or emission side of the imaging device. Magnetic covers over the filter load position on both sides of the filter wheel give easy access to allow filters to be changed quickly. Visible filter allocation numbers allow easy identification of filter positions, and a wide range of adapters for both illuminators and microscopes are available. In addition, Prior’s shutters can be…
Our industry leading bioanalytical solutions have helped our clients develop new peptide therapeutics to improve the quality of life. Combining our experience and cutting-edge technology, we have has developed and validated methods using LC-MS/MS to quantify levels of peptides in plasma at levels as low as 10 pg/mL.
Application: The 35% phenyl equivalent phase provides a higher polarity option compared to columns containing a lower phenyl content, resulting in a greater retention of polar analytes relative to non-polar compounds. Its selectivity is complementary when paired with SLB-5ms for applications that require dual-column confirmatory analysis, such as for environmental analytes (such as pesticides, PCBs, and herbicides). The low…
The SupelMIP SPE line consist s of highly cross-linked polymers that are engineered to extract a single analyte of interest or a class of structurally related analytes with an extremely high degree of selectivity. This is possible because selectivity is introduced during MIP synthesis in which a template molecule, designed to mimic the analyte, guides the formation of specific cavities or imprints that are sterically and chemi…
Dispersive SPE (dSPE), often referred to as the "QuEChERS" method (Quick, Easy, Cheap, Effective, Rugged, and Safe), is modern sample prep technique that is becoming increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products. Using the QuEChERS method, food/agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amoun…
Introducing the Supel-Select SCX SPE Tube from Sigma Aldrich
The SilverQuest™ Silver Staining Kit provides a rapid and easy method to silver stain proteins and DNA in polyacrylamide gels. Silver staining allows detection of most proteins since it is 30-fold more sensitive than staining with colloidal Coomassie® G-250. The SilverQuest™ Silver Staining Kit is specifically designed to provide sensitive silver staining compatible with mass spectrometry analysis. Ideal for rapid preparati…
