(PRLEAP.COM) November 9, 2007 – San Jose, CA This week AnaSpec announced the release of the HiLytePlus™ series of fluorescent dyes. Demonstrating even greater brightness than AnaSpec’s HiLyte Fluor™ line, this series represents the next generation in AnaSpec’s line of high performance fluorescent dyes. With excitation wavelengths of 555, 647 and 750 nm, the HiLytePlus™ series is optimized for long wavelength biomarker labeling.

R&D Manager, Dr. Rich Meyer noted, “Our original HiLyte Fluor™ series was already returning superior performance results in comparison to Cy® and similar dyes. With the introduction of our HiLytePlus™ series, we are looking to distance ourselves even further in terms of performance. By maintaining a price point that is significantly more cost effective than our major competitors, we believe that our HiLytePlus™ series will prove to be extremely competitive in the high performance biomarker labeling market.”

The HiLytePlus™ series dyes are available individually and in AnaTag™ Labeling Kits, labeled secondary antibodies, and labeled streptavidin. The individual dyes are available in different reactive forms – acid, amine, C2 maleimide, hydrazide, and succinimidyl esters (SE).

Goat anti-rabbit antibody was labeled with a mole ratio of 8:1 of each of the indicated dyes in to give a degree of substitution of 3 (+/- 8%). Solutions of rabbit IgG were added to the wells of high-binding 96-well plates, which were then blocked with BSA. A solution of the labeled antibodies was added and the plates, after incubation and washing, were read at the optimal excitation and emission wavelengths.
