| Antigen | Human ACE-2 (1-740aa, glycosylated secreted protein of MW ~120kDa, predicted MW 85 kDa) with His tag was expressed in mouse myeloma cell line NS0 and purified >90% (SDS-PGE). Human ACE-2 protein for WB +ve control, Cat # ACE22-C, is formulated in SDS-PAGE sample buffer (reduced). This preparation is biologically inactive. It is not suitable for ELISA or other applications where native protein is required. It is supplied in 100 ul/vial. For WB, heat once and load 10 ul/lane and visualize with appropriate antibodies. This preparation is intended for qualitative purpose and not to serve as standard of known concentration. Angiogenin protein is ~14 kda. Store frozen in suitable aliquots. Do not freeze, thaw, or hear repeatedly. |
