At ambient temperature. Upon receipt, store the product at the temperature recommended below.
Store the lyophilized protein at –20 to –70 °C. Lyophilized protein remains stable until the expiry date when stored at-20 to –70 °C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at -20 to –70 °C, the protein is stable for 3 months at –20 to –70 °C under sterile conditions after reconstitution. Reconstituted protein can be stored at 4 °C for 1 month under sterile conditions after reconstitution
Quality Control Test
Quantification is done by A280, using the calculated extinction coefficient (14,420 M-1 cm-1).
SDS-PAGE to determine purity of the protein.
LAL TEST to determine endotoxin level.
