Streptavidin, AMCA, 1 mg

Description

AMCA Streptavidin is produced by conjugating streptavidin with a coumarin fluorescent dye, 7-amino-4-methylcoumarin-3-acetic acid. This derivative excites in the ultraviolet (350 nm) and emits in the visible (450 nm) producing an intense blue fluorescence.

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.

Features:

  • Recommended for routine immunofluorescence applications
  • Highly purified and possesses very low non-specific binding properties
  • Extremely high affinity for biotin
  • Has a high fluorochrome to protein ratio
  • Compared to conventional primary and secondary fluorescent techniques, can provide greater sensitivity and lower background staining
