Fluorescein Avidin D is made from highly purified Avidin D and has an optimal fluorochrome to protein ratio. Compared to conventional primary and secondary fluorescent labeling techniques, Fluorescein Avidin D can provide greater sensitivity and lower background staining. For even higher sensitivity and specific applications, see Fluorescein Avidin DCS. Fluorescein Avidin D has an excitation at 495 nm and emission at 515 nm.
Horseradish Peroxidase Avidin D (HRP Avidin D) is produced by a coupling procedure that preserves the high specific activity of the peroxidase. Using biotinylated primary or secondary intermediates and peroxidase-labeled Avidin D, antigens can be localized in histological sections, cytospin preparations, or smears. Horseradish Peroxidase Avidin D is offered as a concentrate (5 mg/ml).
Avidin is a tetrameric biotin binding protein (KD ~1 x 10-14) extracted from egg white. It prevents biotin and biotinylated proteins from binding to Strep-Tactin or Strep-TactinXT, whereas binding of the Twin-Strep-tag and Strep-tagII is not influenced. Biotin and/or biotinylated proteins can potentially reduce the binding capacity of Strep-Tactin as well as Strep-TactinXT and are present in cell lysates and cell culture media, especially from mammalian or insect cells. Thus, if Twin-Strep-tag and Strep-tagII fusion proteins from biotin-containing extracts or media are intended to be purified via Strep-Tactin or Strep-TactinXT affinity chromatography, biotin has to be masked by addition of avidin prior to application onto the resin.
