Product Overview
This rabbit polyclonal antibody detects palmitoyl-protein thioesterase 1 (gene PPT1) in human, mouse and rat samples and is validated for flow cytometry, IHC, ICC/IF and Western blot. The predicted molecular weight is 34.2 kDa, and the supplier reports an observed band at about 34 kDa.
Palmitoyl-protein thioesterase 1 (PPT1) is a lysosomal enzyme that removes palmitate groups from lipid-modified proteins so they can be degraded. It acts on fatty acid thioesters of 14 to 18 carbons. PPT1 deficiency causes infantile neuronal ceroid lipofuscinosis (CLN1), and it is studied in lysosomal storage disease.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL (Human) |
| IHC (frozen sections) | 0.5–1 µg/mL (Human) |
| Immunocytochemistry / Immunofluorescence | 0.5–1 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
Samples with a confirmed band (WB): rat brain tissue, mouse brain tissue, rat liver tissue, mouse liver tissue, HepG2 cells, 293T cells, 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, 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.
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 a confirmed signal (flow cytometry): U937 cells, SiHa cells, THP-1 cells.
Immunogen
Synthetic peptide from the C-terminal region of human PPT1. It differs from the mouse and rat sequences at four residues.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes palmitoyl-protein thioesterase 1 as secreted and also located in the lysosome, Golgi apparatus and endoplasmic reticulum. 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).
