GB1-mCRT(P), GB1-mCRT(C) and mCRT(1-351 ΔP)-mediated inhibition of mCRT(WT) interactions with live and apoptotic MEFs and murine peritoneal macrophages. With live MEFs, the data represent the mean ± SEM of 7 (for GB1-mCRT(P) and GB1-mCRT(C)) or 4 (for GB1-mCRT(1-351 ΔP)) independent measurements. With apoptotic MEFs, the data represent the mean ± SEM of 7 (for GB1-mCRT(C), 6 (GB1-mCRT(P)) or 3 (for GB1-mCRT(1-351 ΔP)) independent measurements. With macrophages, the data represent mean ± SEM of 5 (for GB1-mCRT(P)), 3 (for GB1-mCRT(C)) or 2 (mCRT(1-351 ΔP)) independent measurements, and inhibition by GB1-mCRT(C) in 2 of 5 measurements was insufficient for accurate IC50 estimates. All inhibition studies were undertaken in the presence of 5 mM CaCl2.
