Anti-GABAB R1 (P931) Antibody

This rabbit polyclonal antibody from Antibodies.com is raised against the GABA_B receptor subunit 1, with the immunogen mapping to a region that includes serine 931 (P931), a phosphorylation site relevant to receptor desensitization and membrane trafficking studies. The reagent is supplied as 50 µl of affinity-purified IgG at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide, pH approximately 7.2, and is unconjugated for flexible downstream labeling. Validated applications include Western blot (WB) and immunofluorescence (IF) on human, mouse, and rat samples, supporting cross-species comparison of GABA_B R1 signaling in neuroscience workflows such as inhibitory synaptic transmission, agonist-driven receptor internalization, and phosphorylation dynamics downstream of cAMP/PKA. The single-use vial format is suited to nitrocellulose or PVDF membrane-based WB detection of the ~108 kDa GABAB R1 band, and to IF staining of cultured neurons or fixed brain tissue sections.
