Streptavidin Coating (HS)

The NEXTERION® Streptavidin coating is specifically developed for binding all types of biotinylated molecules. Biotin-tagged molecules are immobilized in a directional way to the streptavidin molecules and applied onto the glass substrate.

The proprietary thin-film deposition coating process produces a very high density, as well as an extremely uniform coating of streptavidin molecules. The resulting surface has a very high binding capacity combined with a low signal variance across a single slide as well as different slides and batches.

Produced in ISO class 5 clean room conditions using a standardized process and running a stringent quality control system, streptavidin coated substrates are available in standard and custom formats.
  • Coating Chemistry
  • Shelf Life
    Six months for sealed packages when stored at –20°C.
    To protect the activity of the streptavidin layer, a protective coating is added on top of the reactive coating prior to packaging. This layer must be removed prior to use by a washing step. The streptavidin layer on Slide HS is very sensitive to elevated temperatures. It is therefore necessary to ship the product in a frozen state with dry ice. The product must immediately be put into a freezer upon arrival. Repeated freeze and thaw cycles should be avoided.

  • Immobilization Method
    Binding via biotin.

  • Probe Types
    • All molecules that can be biotinylated
