Product Overview
This rabbit polyclonal antibody detects spartin in human and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 72.8 kDa, and the supplier reports an observed band at about 78 kDa.
Spartin (SPART) is a protein that localizes to lipid droplets and interacts with LC3 autophagy proteins, acting as a receptor that delivers lipid droplets for degradation by lipophagy. It can also transfer lipids, and loss-of-function mutations cause Troyer syndrome, a form of hereditary spastic paraplegia.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Rat) |
|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HEK293 cells, human HeLa cells, rat brain tissue, rat C6 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 a confirmed signal (flow cytometry): THP-1 cells.
Immunogen
Recombinant human SPART fragment (His205–Val631), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places spartin in the cytoplasm and midbody. Tissue expression noted by UniProt (human): Ubiquitously expressed, with highest levels of expression detected in adipose tissue. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
