VioBright™ 515 and Vio 515 (Em_max 514 nm)

VioBright 515 and Vio 515 are extremely bright dyes for the B1/FITC-channel. The proprietary VioBright multimerization technology results in a 4-fold increase in brightness over the traditional FITC dye. With a 25% reduced spill-over into the B2/PE-channel and high photo stability, these dyes are excellent choices for immunofluorescence microscopy applications.

VioBright 515 at a glance:

• Brightest Vio Dye for the blue laser
  
• Excellent choice for surface markers, in particular for low expressed antigens
  

Vio 515 at a glance:

• Brighter alternative to FITC
• Perfectly suited for intracellular markers, such as cytokines and transcription factors

VioBright™ FITC (Em_max 522 nm)

VioBright FITC is a blue laser (488 nm) excited revolutionary dye, which allows an increased number of FITC molecules per antibody, as compared to conventional FITC conjugation. With brightness similar to PE, VioBright FITC expands the dimensions of multicolor flow analysis. In addition, it provides a bright alternative for confident detection of rare cells, as well as dim and uncharacterized markers.

VioBright FITC at a glance:

• Brightness similar to PE for confident detection of low-expressed and rare markers
  
• Excellent bright alternative to PE for flexible multicolor panel design
  
• Signal detectable in standard FITC channel with peak excitation and emission wavelength of 496 nm and 522 nm, respectively
  
• Works with your standard staining protocol
