Xa Cleavage Control Protein The Xa Cleavage Control Protein is intended for conducting control digests in parallel with experimental samples, or to test cleavage under customized buffer conditions. The 53.1-kDa Xa Cleavage Control Protein is cleaved into two proteolytic fragments of 35.8 kDa and 17.3 kDa, which are easily visualized by standard SDS-PAGE followed by Coomassie blue staining. The Xa Cleavage Control Protein also features an amino terminal S•Tag™ sequence enabling sensitive detection of the 17.3 kDa proteolytic product with Western Blot reagents. 产品信息 Avoid freeze/thaw 是的 商店和运输信息 Storage -20°C Ship Shipped with Blue Ice or with Dry Ice Irritant
