Frequently asked questions for: Sil-Select™ Plus

FAQ1: Does Sil-Select Plus contain antobiotics ?
No it doesn't.
if you want to add your own antibiotics we suggest to add 10mg of pharmaceutical grade gentamicin per liter of medium.

FAQ2: How long can I use Sil-Select Plus after opening the bottle?
2 factors limit the shelf life of a product after opening the bottle:

  • Gass exchange: influences the pH
  • Contamination with viable organisms

  • We have performed open bottle tests on our media for up to 7 days and found that the product parameters stayed within the specifications in this time period, taking into consideration that the bottle was opened under sterile conditions and the product was stored at 2-8°C after opening.

    FAQ3: Can we make our own gradients in stead of using your upper and lower layer density gradients ?
    Yes you can, for that you would need to order Sil-Select Stock in stead of Sil-Select Plus.
    Note however that we have found that our Sil-Select Plus gradients have been optimized for maximum efficiancy in selection spermatozoa.
