R spondin 1/RSPO1, His, Mouse
目录号 : GC27276The R-spondins are members of a superfamily of thrombospondin type 1 repeat (TSR-1)-containing proteins. The prototype member (discovered in 1971) was isolated from platelets that had been stimulated with thrombin, and was therefore designated 'thrombin-sensitive protein.
Sample solution is provided at 25 µL, 10mM.
