Our Anti-FMRP (Ser499) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects chicken, human, mouse, and rat FMRP (Ser499) and is antigen affinity purified from pooled serum. It is great for use in WB, IHC.
Western blot of rat hippocampal lysate showing specific immunolabeling of the ~71 kDa FMRP protein phosphorylated at Ser499 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is completely eliminated by lysate treatment with lambda phosphatase (400 units/100uL lysate for 30 min).
