Amplification of fluorescent signals can be easily achieved with our biotinylated secondary antibodies followed by our highly purified fluorochrome-labeled streptavidin or avidin. Using a biotin/avidin or biotin/streptavidin detection system results in an additional layer of amplification over a directly conjugated secondary antibody.

Kit Contents:

250 µg of three fluorescent streptavidin products: Fluorescein Streptavidin, Texas Red® Streptavidin and AMCA Streptavidin.  

The kit supplies enough of each derivative to label 250-500 sections or cell suspensions.

  • Fluorescein Streptavidin is yellow-green (excites at 495 nm and emits at 515 nm)
  • Texas Red® Streptavidin is deep red (excites at 595 nm and emits at 615 nm)
  • AMCA Streptavidin is blue (excites at 350 nm and emits at 450 nm)

Technical Information

Vector Laboratories fluorochrome-conjugated streptavidin and avidin reagents are highly purified and possess very low non-specific binding properties. They have extremely high affinity for biotin. These fluorescent conjugates can be used to detect biotinylated secondary antibodies and other macromolecules in applications such as immunofluorescence, in situ hybridization, or flow cytometry.
