DLK1 (Protein delta homolog 1; Preadipocyte factor 1; Pref-1) is a regulator of adipocyte differentiation found in serum and urine. DLK1 might be a decoy ligand. Serum or plasma levels of soluble DLK1 affect negatively or positively adipogenesis and control mesenchymal cell fate. DLK1 is frequently upregulated in myelodysplastic syndrome (MDS) patients compared to non-leukemic individuals.
Sequence:
Signal peptide and extracellular domain of human DLK1 (aa 1-303) are fused at the C-terminus to a FLAG(R)-tag.
Storage and Stability:
Short-term Storage: +4 degrees C
Long-term Storage: -20 degrees C
Working aliquots are stable for up to 3 months when stored at -20 degrees C.
