Product Overview
This rabbit polyclonal antibody targets transcription factor HLF in human samples and is validated for flow cytometry, ICC/IF and Western blot. The predicted molecular weight is 33.2 kDa, and the supplier reports an observed band at about 35 kDa.
HLF (hepatic leukemia factor) is a PAR bZIP transcription factor, related to DBP and TEF, that shows circadian expression. It helps keep hematopoietic stem cells quiescent and regulates genes in liver and other tissues, and it became known through the E2A-HLF fusion found in a form of childhood acute lymphoblastic leukemia.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human) |
|---|---|
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
Samples with a confirmed band (WB): human HepG2 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% 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 (ICC/IF): HepG2 cells.
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Synthetic peptide from the C-terminal region of human HLF. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human. UniProt places transcription factor HLF in the nucleus. Tissue expression noted by UniProt (human): Highly expressed in liver. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
