Protein Synthesis Initiation Factor 2 alpha (Eukaryotic Translation Initiation Factor 2 alpha, Eukaryotic Translation Initiation Factor 2 Subunit 1 alpha 35kDa, eIF2 alpha, eIF2alpha, eIF-2-alpha, eIF-2alpha, eIF 2a, eIF2a, eIF-2a, CDA02, eIF2S1)

May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
