BioLock

Biotin blocking solution for lysates and culture supernatants

€143.00*

Content
BioLock is a ready-to-use biotin blocking solution which contains the tetrameric biotin binding protein avidin. BioLock prevents biotin and biotinylated proteins from binding to Strep-Tactin® or Strep-Tactin®XT, whereas binding of the Twin-Strep-tag® and Strep-tag®II is not influenced. Biotin and/or biotinylated proteins can possibly reduce the binding capacity of Strep-Tactin® as well as Strep-Tactin®XT and are present in cell lysates and cell culture media, especially from mammalian or insect cells. Thus, if Twin-Strep-tag® and Strep-tag®II fusion proteins from biotin-containing extracts or media are intended to be purified via Strep-Tactin® or Strep-Tactin®XT affinity chromatography, biotin has to be masked by addition of BioLock prior to application onto the resin.
