Pfizer Animal Genetics, a business unit of Pfizer Animal Health, this week launched Clarifide, a genomic test for the evaluation of dairy females.

The new test is a 3,000-marker DNA array that was developed by Pfizer in collaboration with the US Department of Agriculture's Agricultural Research Service and Illumina. It delivers genomic predicted transmitting ability values for 30 production, health, and type traits, and nine composite indexes that provide insights into animals' future genetic potential early in an animal's life, according to the firm.

Pfizer Animal Genetics said it has already implemented Clarifide in partnership with several unnamed commercial dairies from across the US to demonstrate the value of the test.


Fluidigm this week launched its reusable FR48.48 Dynamic Array integrated fluidic circuit, a reusable biochip for SNP genotyping. Each chip can be used up to five times and is able to produce results for 48 samples across 48 assays for a total of up to 11,520 genotypes over the five uses, Fluidigm said. The company initially introduced the reusable chip in June (BAN 6/8/2010).

Fluidigm has also launched the IFC Controller WX, a device that automatically performs fast loading or cleaning of its reusable IFCs. According to the firm, the reusable FR48.48 chip can be loaded in 30 minutes and the overall time for loading and thermal cycling is about one hour, compared to approximately three hours for single-use 48.48 Dynamic Array IFCs.
