Affymetrix this week released version 1.1 of its ChAS Chromsome Analysis Suite software,
The the new software includes improved allele peaks algorithm and loss of heterozygosity detection algorithm. Additionally, the minimum and default values of the median-smooth-marker-count algorithm have been changed.
Zoiray Technologies recently launched its Spectral Reflectance Imaging Biosensor system, a multiplexed immunoassay platform for life science research and clinical diagnostics. The SRIB supports array-based immunoassays that identify the presence of specific protein biomarkers in blood, urine, or saliva, according to the Boston-based firm.
Designed by Wellesley, Mass.-based Bodkin Design and Engineering, the SRIB incorporates a class IIIb tunable laser, high-resolution camera, fluidics, and digital control. It automatically carries out specimen delivery, reagent introduction, optical interrogation, specimen disposal, and data analysis, the firm said.
During its operation, a biochip containing active proteins is loaded into the device. The specimen and reagents are then delivered to the reaction flow cell, where incubation takes place. The sample is optically probed with the laser and evaluated. Zoiray said that key applications of the SRIB include biomedical research, disease pathogen identification, and homeland security.
