High purity SDS is dissolved in triple glass distilled/deionized, sterile water to 10% (w/v). The ability of each lot to function as an effective topoisomerase denaturant is tested and verified for each lot.
The product is shipped and stored at ambient temperature. Placement at 4°C will lead to precipitation of the detergent. Warming briefly to 37°C will re-dissolve the precipitate.
