PA28, alpha, CT (Proteasome Activator 28-alpha subunit)-PE

May be stored at 4 degree C for short-term only. For long-term storage, store at -20 degree C. Aliquots are stable for at least 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Reacts with the C-terminal region of mouse, rat, human, crab-eating macaque (monkey) and pig PA28a. On Western blots, it identifies the target band at ~28kD. Faint bands of unknown origin may be observed in some homogenate or lysate preparations. Reactivity has been confirmed with mouse spleen, liver and lung homogenates, as well as with human BC-1 B-lymphocyte lymphoma lysates. Based on amino acid sequence homology, cross-reactivity with rat is expected.
