Anti-Synapsin I pS9 (Rabbit) antibody is suitable for use in Western Blotting and IHC. Specific conditions for reactivity should be optimized by the end user. Expect a band of approximately 78 kDa in size corresponding to synapsin I doublet protein phosphorylated at Ser9 in the appropriate cell lysate or extract. This antibody also weakly labels the approximately 55 kDa synapsin II protein which has a similar phosporylation site to that of Ser9 on synapsin I. Researchers should determine optimal titers for applications that are not stated below.
