Fluorescent Nickel sensor. A group from University of California, Berkeley, headed by Christopher J. Chang has developed a turn-on fluorescent senor for detecting nickel in living cells. The sensor was constructed starting with BODIPY, or boron dipyrromethene fluorescent dye combined with a nickel cation receptor, creating the sensor NS1. Absorption is at 495 nm and emission at 507 nm. See BioPhotonics, page 12-13, March 2010.

A flow cytometer for detecting somatic cells in milk. Advanced Instruments' new Delta Instruments SomaScope(TM) Smart has received approval for sale in the U.S. from the Lab Committee of the National Conference on Interstate Milk Shipments (NCIMS) as the industry's first somatic cell counter to feature a Light Emitting Diode (LED)as its light source. The new SomaScope Smart uses an LED instead of an HBO lamp to illuminate the stained cells in a sample and detect them with dual photomultiplier tubes. The SomaScope Smart somatic cell counter is for use by dairy processors, payment laboratories, veterinary laboratories, and dairy herd improvement (DHI) laboratories, providing analysis for somatic cells in cow, sheep, goat, buffalo, and camel milk.
