Vector Labs is closed to observe Independence Day (US Holiday) on Thursday, July 4th.
We will be back in the office on Friday. We will respond to emails upon our return. Have a wonderful day.

Fluorescein Avidin DCS, Cell Sorting Grade (A-2011-1)



Avidin DCS, Fluorescein labeled, is a cell sorter grade of Fluorescein Avidin D. Through the development of a new method of fluorescein labeling we are able to incorporate more fluorochrome into a protein without altering the properties of the protein. Not only does the Fluorescein Avidin DCS have an optimal F/P ratio, the efficiency of fluorescence is also increased. In addition to the improved conjugation technique, we employ a purification step to reduce nonspecific binding which can hamper resolution in cell sorting and other applications.

Technical Information

Although this product has been designed for cell sorting, it can also be used in fluorescent microscopy when higher sensitivity and lower background staining are necessary. This derivative is preferred when using the amplification procedure with Biotinylated Anti-Avidin D. 

  • Excitation maximum:  495 nm
  • Emission maximum:  515 nm
  • Color:  Green
