Request InfoWyatt Technology Corp.SANTA BARBARA, Calif., Sept. 8, 2011 — Wyatt Technology Corp. has released the Calypso, a composition-gradient multiangle light-scattering (CG-MALS) system that achieves accurate measurements of biomolecular interactions. It can determine both the affinity and binding stoichiometry for macromolecules in solution, with no need for sample tagging or immobilization that could influence the interaction. Antibody-antigen binding, hormone-receptor interactions and many other common biomolecular interactions occur at stoichiometries other than 1:1. Conventional separation techniques, such as size exclusion chromatography MALS and...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...BioPhotonics.com April 2024 IssueSurface-Mount MiniLEDsThe VLMB2332T1U2-08 and VLMTG2332ABCA-08 from Vishay Intertechnology are blue and true green, respectively, surface-mount LEDs in a miniLED package for medical light treatment, heart rate monitoring,...Photonics.com 9/14/2022Multi-sensor Coordinate Measuring MachineThe FlexPoint® 12-Series of large-format multi-sensor coordinate measuring machines from Optical Gaging Products is designed for large, heavy parts with complex dimensions and tolerances. ...Photonics.com 8/24/2022Ethylene Oxide Monitoring SystemThe Ambient Air Monitoring System for Ethylene Oxide (EtO) has been announced by Picarro Inc., providing a continuous, automated solution for community monitoring stations and industrial fencelines....ARTICLESPhotonics.com 4/7/2023Ams OSRAM Wraps Digital Systems Business Divestiture: Week in Brief: 04/07/23Electro Optic Systems (EOS) secured a conditional contract to supply remote weapon systems (RWS) to Ukraine valued at up to $80 million.
