Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to a residues surrounding Met371 of human DLK1. Antibodies are purified by protein A and peptide affinity chromatography.

Background

DLK1 (delta-like-1), also known as fetal antigen 1 (FA1) and preadipocyte factor 1 (pref-1), is a member of the epidermal growth factor (EGF)-like family of proteins, containing six tandem EGF-like repeats (1,2). DLK1 is a paternally expressed, imprinted gene that plays an important role in normal development and in the maintenence of homeostasis of adipose tissue mass (3). DLK1 deficient mice display growth retardation, obesity, skeletal malformation, and increased serum lipid metabolites (4). It has been reported that the ectodomain of DLK1 is shredded from the cell surface and inhibits adipocyte differentiation ( 5-7).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
