Product Overview
This rabbit polyclonal antibody recognizes left-right determination factor (gene lft1) in zebrafish samples and is validated for Western blot.
In zebrafish, lft1 encodes Lefty1, a secreted TGF-β superfamily protein that antagonizes Nodal signaling. It limits the range of Nodal activity during early embryogenesis, helping pattern the mesoderm and endoderm and establish left–right asymmetry, and zebrafish is a key model for studying this role.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Zebrafish) |
|---|
Samples with a confirmed band (WB): zebrafish head tissue, whole female zebrafish tissue, whole male zebrafish tissue.
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.
Immunogen
Recombinant zebrafish LFT1 fragment (Arg19–Lys312), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with zebrafish. UniProt describes left-right determination factor as a secreted protein. 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).
