S1P ELISA kits can refer to multiple targets, such as sphingosine-1-phosphate and site-1-protease. Spingosine-1-phosphate is a bioactive metabolite of sphingosine involved in cell signaling, regulation of vascular and immune systems and regulation of disease progression. It associates with high density lipoproteins (HDL) and can also act as a ligand for the G-coupled protein receptor S1PR1. Site-1-protease is also known as membrane-bound transcription factor site-1 protease (MBTPS-1). It is an enzyme that mediates proteolytic activation and cleavage.
