This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human Pref-1 / DLK1 / FA1. The suggested diluent is suitable for the analysis of most cell culture supernate samples. Diluents for complex matrices, such as serum and plasma, should be evaluated prior to use in this DuoSet ELISA.
Optimized capture and detection antibody pairings with recommended concentrations save lengthy development time
Development protocols are provided to guide further assay optimization
Assay can be customized to your specific needs
Economical alternative to complete kits
Streptavidin conjugated to horseradish-peroxidase (Streptavidin-HRP)

Pref-1 (preadipocyte factor 1), also known as deltalike 1 (DLK1) and fetal antigen 1 (FA1), is a member of the Notch/Delta/Serrate protein family. It is a transmembrane protein that can be proteolyically
cleaved to generate soluble forms. Pref-1 is believed to be a co-ligand for Notch signaling, enhancing or inhibiting Notch activation following binding of a ligand. It is expressed in numerous endocrine cells,
and is highly expressed in preadipocytes, but not in mature adipocytes. In adipose tissue, Pref-1 inhibits adipogenesis and is often used as a preadipocyte marker.
