Anti-DLK1 Antibody

Raised in rabbit against Delta Like Non-Canonical Notch Ligand 1 (DLK1), this polyclonal antibody is supplied by Antibodies.com as an unconjugated primary reagent optimized for western blot workflows. The preparation is provided at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, shipped as 100 µl of ready-to-use stock in a single vial.

DLK1 is an EGF-like repeat-containing transmembrane protein and paternally imprinted gene with documented roles in preadipocyte differentiation, fetal liver hematopoiesis, and several solid tumor contexts including hepatocellular carcinoma and neuroendocrine tumors, where it is frequently tracked as a marker of progenitor or stem-like populations. Confirmed reactivity spans human, mouse, and rat samples, supporting comparative work across cell line panels and primary tissue.

The unconjugated rabbit IgG format lets researchers pair this reagent with their preferred anti-rabbit secondary antibody for chemiluminescent or fluorescent western blot detection of endogenous DLK1 in cell lysates and tissue homogenates. Storage at -20 °C in the supplied glycerol buffer is recommended; the 50% glycerol content protects against freeze-thaw cycling, so aliquoting is not strictly required for short-term use. Thaw on ice and mix gently before each use, and protect from light is not required since the antibody is unconjugated.
