Product Overview
This rabbit polyclonal antibody targets rho guanine nucleotide exchange factor 12 (gene ARHGEF12) in human and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 173.2 kDa, and the supplier reports an observed band at about 220 kDa.
Rho guanine nucleotide exchange factor 12 (ARHGEF12, also called LARG) activates RhoA by promoting the exchange of GDP for GTP. Like related RGS-domain RhoGEFs, it links Gα12/13-coupled receptors to Rho signaling and is studied in cytoskeletal regulation and smooth muscle contraction.

Samples with a confirmed band (WB): human HEL cells, human K562 cells, rat brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with a confirmed signal (flow cytometry): HL-60 cells.
Immunogen
Recombinant human LARG/ARHGEF12 fragment (Thr4–Ser254), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places rho guanine nucleotide exchange factor 12 in the cytoplasm and membrane. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
