Molecular Devices this week introduced the FLIPR Calcium 4 Assay Kit, its next-generation no-wash calcium flux assay.

Molecular Devices first introduced its no-wash, cell-based calcium assay kits for GPCR screening in 1999. The new kit includes a masking technology licensed exclusively from Bayer AG, Molecular Devices said.

The company's kits now include Calcium, Calcium 3, and Calcium 4, all of which are homogenous mix-and-read assays optimized for use with MDCC's FLIPR fluorometric imaging plate readers.


Evident Technologies this week released two new quantum dot tags for use in life science applications: T2-MP EviTag labels and EviFluor conjugates.

The T2-MP EviTags are quantum dot-based, conjugation-ready fluorescent labels with a bioactive surface that features Evident's Molecular Plating surface technology, which help provide improved brightness, photostability, flexibility, and sensitivity, Evident said, They are available with either amine or carboxyl terminal groups, or with a non-functional bioactive surface.

The EviFluors are ready-to-use activated quantum dot conjugates coupled to secondary antibodies and other proteins, Evident said. They are available conjugated to secondary antibodies, streptavidin, and biotin.

EviTag labels are available in colors from Lake Placid Blue (490 nm) to Jonamac deep reds (680 nm); while the EviFluor conjugates are available in Adirondack Green (520 nm), Fort Orange (520 nm), Maple Red-orange (620 nm), and Jonamac (680 nm), Evident said.
