Thanks for your inquiry. Since this protein is a futures contract at present, we do not detect the protein activity, so there is no guarantee that the protein is 100% active. What we do for this protein is the full length of mature protein, which is purified under mild conditions and is theoretically active. In theory the protein is dimer.
