Human Delta-like protein 1 (DLL1) ELISA Kit

A sandwich ELISA kit from Assay Genie is designed for the quantitative measurement of human Delta-like protein 1 (DLL1), a key ligand of the NOTCH1, NOTCH2 and NOTCH3 receptors in the Notch signaling pathway. The assay is intended for use with human samples and is suitable for detecting DLL1 in serum, plasma, and cell culture supernatants. Because DLL1 plays a vital role in regulating cell differentiation and development, and its dysregulation has been linked to cancer, autoimmune diseases, and developmental abnormalities, the kit serves as a valuable research tool for studying these conditions.

Reported performance characteristics include a detection range of 31.2–2000 pg/mL, a sensitivity of 10 pg/mL, an intra-assay CV of 5.4%, and an inter-assay CV of 8.6%. Linearity has been demonstrated across dilution factors from 1:2 to 1:16 in serum, EDTA plasma, and heparin plasma. Recovery averages 98% in serum (range 92–104%) and 100% in plasma (range 94–106%).
