Patent number: 11808697Abstract: Systems for protein quantitation using a Fabry-Perot interferometer. In one arrangement, a quantitation device includes an infrared source, a sample holder, and a Fabry-Perot interferometer positioned to receive infrared radiation from the source passing through a sample on the sample holder. A band pass optical filter sets the working range of the interferometer, and radiation exiting the interferometer falls on a detector that produces a signal indicating the intensity of the received radiation. A controller causes the interferometer to be tuned to a number of different resonance wavelengths and receives the intensity signals, for determination of an absorbance spectrum.Type: GrantFiled: July 29, 2022Date of Patent: November 7, 2023Assignee: Bio-Rad Laboratories, Inc.Inventors: Evan Thrush, Steven Swihart, William Strong, Trey Marlowe, Li Lu

Patent number: 10788423Abstract: Analyte arrays such as solutes in a slab-shaped gel following electrophoresis, and particularly arrays that are in excess of 3 cm square and up to 25 cm square and higher, are imaged at distances of 5 cm or less by either forming sub-images of the entire array and stitching together the sub-images by computer-based stitching technology, or by using an array of thin-film photoresponsive elements that is coextensive with the analyte array to form a single image of the array.Type: GrantFiled: March 28, 2017Date of Patent: September 29, 2020Assignee: Bio-Rad Laboratories, Inc.Inventors: John Barich, Renee Lemaire-Adkins, David Neaz, Ariel Notcovich, Paul Patt, Ryan Short, Steven Swihart, Evan Thrush, Trey Marlowe

Patent number: 10634614Abstract: Devices and methods are disclosed for the substantially uniform epi-illumination of samples such as western blots using high power lasers. The uniformity of illumination is provided by particular configurations of optical diffusers, spatial or temporal laser modalities, or numbers of lasers. The increased excitation light produced by the high power lasers can enhance fluorescence emission signal strength and reduce required imaging exposure times.Type: GrantFiled: August 23, 2018Date of Patent: April 28, 2020Assignee: Bio-Rad Laboratories, Inc.Inventors: Evan Thrush, Steven Swihart
