Questions

  1. Hi. I would like to know for how long I can store X-Gal (-20°C) before its degradation. Thanks

    1 answer
    1. This product is assigned a product retest date of approximately 2.5 years from the date of Quality release and is considered to be a stable compound. Products that, while considered stable, may be subject to degradation over time are assigned a periodic retest date to confirm quality.  The lot specific retest date is reported on the Certificate of Analysis.
