About CD28
The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

About NovaFluor Blue 610 / 70S
The NovaFluor family of fluorescent polymers from Thermo Fisher Scientific are a novel reagent for traditional and spectral flow cytometry. These fluorophores are comprised of a DNA backbone polymer integrated with fluorophore substituted nucleosides to create a potent donor molecule. Tandem fluophores with long Stokes' Shift enable brighter, spectrally discrete, tunable fluorescent polymers as an alternative to traditional simple organic structures, protein-based fluorophores as well as the Horizon Brilliant™ family of fluorescent polymers from BD. NovaFluor Blue 610/70S is designed to be discreetly excited by the 488 nm laser and has an excitation peak at 496 nm and an emission peak at 614 nm. NovaFluor Blue 610/ 70S is bigger and brighter than NovaFluor Blue 610/ 30S.
