Our Anti-GABAB Receptor (Ser923), R1-Subunit rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse and rat GABAB Receptor (Ser923), R1-Subunit and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of rat synaptic membrane lysate showing specific immunolabeling of the ~102 kDa GABAB R1 protein phosphorylated at Ser923 in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 min).
