Our Anti-Synapsin (Ser549) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse and rat Synapsin (Ser549) and is antigen affinity purified from pooled serum. It is great for use in WB, ICC.
Western blot of rat cortical lysate showing specific immunolabeling of the ~78 kDa synapsin I phosphorylated at Ser549 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 minutes).
