-
Background: Sar1 belongs to a small GTPase superfamily and GTP binging activity. This protein is involved in intracellular protein transport. There are two different non-clathrin-coated vesicles that are responsible for transport between ER and the Golgi. Coat protein complexes involving membrane-associated GTP binging proteins – Arf1 and Sar1p for COPI and COPII are needed for formation of COP-coated vesicles. Sar1p is a cytosolic protein. It is temporarily recruited onto the membranes of the ER.

| 2009-07-21This antibody was able to detect Sar1 in the fern Pteris vittata. I used the recommended dilution of 1:500 and incubated the antibody for at least 8 hours at room temp (22 deg). It worked very well!
