This has not been fully investigated, but we do not recommend use of SDS. Low concentrations, 0.1 – 0.5% of non-ionic detergents have been used with some of our products, but to what extent they alter separation performance, is unknown. If non-ionic detergents are to be used, generally we recommend that they be of no greater than 0.1% before applying to the beads. So for tissue lysates for example at higher %, dilute the sample before application.

The products have a shelf life typically 6 months to 1 year. We ship at room temperature, but recommend storage at 4°C upon receipt. Do not freeze.
