Agilent Technologies, Bioident

Premium
Agilent Technologies this week launched its Human 244K CpG Island Microarrays for studying epigenetics.
 
Specifically, the arrays can be used for studying DNA methylation changes that can be correlated to cancer formation, organism development, genomic imprinting, gene silencing, and chromatin stability, Agilent said.
 
The company added that it plans to add other organisms to its CpG array line in coming months. 
 

 
Bioident, a subsidiary of Nanoident, this week launched its PhotonicLab Platform, a disposable lab-on-a-chip system that the firm claims can enable mobile, real-time and multi-parameter detection of chemical and biological substances.
 
According to Wasiq Bokhari, Bioident’s CEO, PhotonicLab uses a 900-site microfluidics array, as well as a hand-held detector that can wirelessly transfer the data from the chip to a PC or laptop.
 
Bokhair told BioArray News last week that the company is looking to partner with other companies to co-develop and market applications for water analytics, multi-analyte detection, and multiplexed molecular diagnostic assays as possible applications based on the PhotoLab Platform.
