The data sheets for Products SDS7B2 and B2787do not provide a specific recommendation on how long the solutions of these molecular weight marker mixtures can be kept frozen at -20°C. What information can you provide?
Our R&D group recommends that after reconstitution, the solutions should be divided into aliquots and immediately frozen; avoid repeated freeze / thaw cycles. The aliquots should last at least a year at -20°C. Storage at -80°C would even be better, if it is convenient.
