Human PTDSS1 (Phosphatidylserine synthase 1) ELISA KIT (HUFI04964)

Assay Genie supplies a research-use immunoassay kit for quantifying human phosphatidylserine synthase 1 (PTDSS1), an integral endoplasmic reticulum membrane enzyme that catalyzes the calcium-dependent base-exchange conversion of phosphatidylcholine and free L-serine into phosphatidylserine and choline. This head-group exchange reaction is the major route of phosphatidylserine biosynthesis in mammalian cells and supports critical downstream processes including the maintenance of plasma membrane lipid asymmetry, propagation of the blood coagulation cascade, and the display of phosphatidylserine on the outer leaflet that marks apoptotic cells for phagocytic engulfment.

The microplate-format kit is configured as 96 Assays and is shipped with the full reagent set required to run the standard protocol. Lipid biochemists, neurobiologists, and oncology researchers apply this measurement to investigate phosphatidylserine-dependent signaling, explore membrane biogenesis in cancer cell phenotypes, and examine phospholipid remodeling linked to neurodegeneration. Reagents should be kept refrigerated upon arrival and allowed to reach room temperature before opening. The kit is intended for research use only and is not validated for diagnostic testing.
