Product Overview
This rabbit polyclonal antibody detects PH and SEC7 domain-containing protein 1 (gene PSD) in human, mouse and rat samples and is validated for ELISA and Western blot. The predicted molecular weight is 109.5 kDa, and the supplier reports an observed band at about 130 kDa.
PSD (also called EFA6A) is a guanine nucleotide exchange factor with a Sec7 domain and a pleckstrin homology domain. It activates the small GTPase ARF6 at the plasma membrane, influencing endocytic recycling and actin remodeling, and it is enriched in the brain.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): rat brain tissue, mouse 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, 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.
Immunogen
Recombinant human PSD fragment (Thr536–Lys803), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places PH and SEC7 domain-containing protein 1 in the cell membrane, cell projection and cleavage furrow. Tissue expression noted by UniProt (human): Isoform 2 is expressed in the brain. 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).
