背景 | Pref-1 (Preadipocyte factor 1; also DLK-1 and FA1) is a 58-65 kDa member of the Notch/Serrata/Delta family of proteins. It is expressed in prechondrocytes and preadipocytes and appears to block progenitor cell differentiation into mature cell lineages. Mature human Pref-1 is a 360 amino acid (aa) type I transmembrane N- and O-linked glycoprotein. It contains a 280 aa extracellular region (aa 24-303), a 24 aa transmembrane segment (aa 304-327), and a 56 aa cytoplasmic domain (aa 328-383). The extracellular region contains six EGF-like domains, and undergoes proteolytic cleavage to generate a bioactive 50 kDa fragment, plus three 25‑31 kDa fragments that show no activity. There are multiple potential splice variants. One shows a deletion of aa 229-301, a second possesses a six aa substitution for aa 1‑52, a third shows a deletion of aa 210-277, while a fourth contains a six aa substitution for aa 207-383. Over aa 24-297, human Pref-1 shares 82% aa identity with mouse Pref-1. |

Detection of Pref‑1/DLK1/FA1 in HepG2 Human Cell Line by Flow Cytometry. HepG2 human hepatocellular carcinoma cell line was stained with Mouse Anti-Human Pref‑1/DLK1/FA1 Monoclonal Antibody (Catalog # MAB1144, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). | |
Pref‑1/DLK1/FA1 in HepG2 Human Cell Line. Pref‑1/DLK1/FA1 was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line using Mouse Anti-Human Pref‑1/DLK1/FA1 Monoclonal Antibody (Catalog # MAB1144) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell membranes. View our protocol for Fluorescent ICC Staining of Cells on Coverslips. |
