Profile: G W C Technology, Inc. offers label-free analysis systems for researchers in proteomics, drug discovery, genomics, protein array development and materials science research. SPRimager®II is designed for analysis of molecular interactions in an array format. The entire array is exposed to the same analyte in the 1-cm flow cell, eliminating the channel-to-channel variability inherent in multichannel systems and allowing for simultaneous capture of data for all probes on the array. It uses surface plasmon resonance imaging (SPRi) to detect molecules as they bind to probes on the surface of the array. Fourier-transform surface plasmon resonance systems perform wavelength scanning SPR detection in the near infra-red.
