Product Overview
This rabbit polyclonal antibody detects liprin-alpha-1 (gene PPFIA1) in human samples and is validated for Western blot, IHC, ICC/IF and ELISA. The predicted molecular weight is 135.8 kDa, and the supplier reports an observed band at about 160 kDa.
Liprin-α1 (PPFIA1) is a scaffold protein that binds the LAR family of receptor tyrosine phosphatases. It helps position these phosphatases at specific sites on the plasma membrane and is involved in focal adhesion turnover and cell migration. Liprin-α1 is studied in cell motility and cancer invasion.

Samples with a confirmed band (WB): human HeLa cells, human 293T cells, human MCF-7 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, 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 confirmed staining (IHC): human gastric signet ring cells carcinoma tissue, human liver cancer tissue, human rectal differentiated adenocarcinoma 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 EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): A431 cells.
Immunogen
Recombinant human PPFIA1 fragment (Ala198–Cys1202), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places liprin-alpha-1 in the cytoplasm. Tissue expression noted by UniProt (human): Ubiquitous. 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).
