Product Overview
This rabbit polyclonal antibody targets disks large-associated protein 1 (gene DLGAP1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 108.9 kDa, and the supplier reports an observed band at about 130 kDa.
DLGAP1 (also called GKAP or SAPAP1) is a postsynaptic scaffold protein that binds the guanylate kinase domain of PSD-95 family proteins. It links them to Shank proteins, helping to organize the postsynaptic density at excitatory synapses. DLGAP1 is studied in synapse structure and neuropsychiatric research.

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, 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): A549 cells.
Immunogen
Recombinant human DLGAP1 fragment (Asp17–Gln319), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places disks large-associated protein 1 in the cell membrane, postsynaptic density and synapse. Tissue expression noted by UniProt (human): Expressed in 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).
