Product Overview
This rabbit polyclonal antibody targets ras GTPase-activating-like protein IQGAP1 in human, mouse and rat samples and is validated for ELISA, flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 189.3 kDa, and the supplier reports an observed band at about 189 kDa.
IQGAP1 is a large scaffold protein that binds actin, calmodulin, active CDC42 and RAC1 and many signaling partners. It organizes the actin cytoskeleton, supports cell–cell adhesion and migration, and brings together components of the MAPK pathway. It is widely studied in cell motility, signaling and cancer.

Samples with a confirmed band (WB): human placenta tissue, human U-87MG cells.
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, 50 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 1:10000, ECL detection.
Samples with confirmed staining (IHC): human intestinal cancer tissue, human mammary cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Samples with confirmed staining (ICC/IF): U2OS cells.
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
E. coli-derived human IQGAP1 recombinant protein (D1374-K1657).
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places ras GTPase-activating-like protein IQGAP1 in the cell membrane, nucleus, cytoplasm and apical cell membrane. Tissue expression noted by UniProt (human): Expressed in the placenta, lung, and kidney. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
