Proteasome 20S (human), (purified)

As indicated on product label or CoA when stored as recommended. 20S Proteasome remains relatively stable and active so long as repetitive freeze-thaw cycles are avoided. It has been demonstrated that 20S proteasome undergoes only slow loss of activity when stored at 4°C for up to six months. If it is to be used on a regular basis, it is recommended that the material should be stored between 0°C-4°C during the duration of use. For longer term storage the material may be dispensed as single use aliquots and stored at -80°C.
