Western blot shows lysates of 3T3-L1 mouse embryonic fibroblast adipose-like cell line and mouse embryo tissue. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Mouse Pref-1/DLK1/FA1 Monoclonal Antibody (Catalog # MAB8634) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Pref-1/DLK1/FA1 at approximately 45-50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Pref‑1/DLK1/FA1 in 3T3‑L1 Mouse Cell Line by Flow Cytometry.

3T3-L1 mouse embryonic fibroblast adipose-like cell line was stained with Rabbit Anti-Mouse Pref-1/DLK1/FA1 Monoclonal Antibody (Catalog # MAB8634, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Allophycocyanin-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # F0111).

Pref‑1/DLK1/FA1 in Mouse Embryonic Liver Tissue.

Pref-1/DLK1/FA1 was detected in immersion fixed frozen sections of mouse embryonic liver tissue (13 d.p.c.) using Rabbit Anti-Mouse Pref-1/DLK1/FA1 Monoclonal Antibody (Catalog # MAB8634) at 1 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC003). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membrane.

Background: Pref-1/DLK1/FA1

Pref-1 (Preadipocyte factor 1), also known as Protein delta homolog 1, DLK1, FA1 and Fetal antigen 1, is a 45-60 kDa transmembrane glycoprotein that is highly expressed in fetal liver, placenta, adult adrenal gland, brain, testis and ovary. Expression of Pref-1 is elevated in liver after birth but starts to decline around postnatal day 16. Mature mouse Pref-1 is a 362 amino acid (aa) type I transmembrane N- and O-linked glycoprotein. It contains a 282 aa extracellular region (aa 24-305), a 24 aa transmembrane segment (aa 306-329), and a 56 aa cytoplasmic domain (aa 330-385). It contains 6 EGF-like domains and is involved in embryonic skeletal system development. Pref-1 inhibits preadipocyte proliferation by regulating their entry into G1/S-phase and represses preadipocyte differentiation. It is a master regulator of preadipocyte homeostasis and adipose tissue expansion. Pref-1 manipulation may, therefore, be utilized in obesity treatments. Mouse Pref-1 shares 85% and 94% aa identity with human and rat Pref-1, respectively
