Rat Alkaline Sphingomyelinase (Alk-Smase) ELISA Kit

Researchers studying sphingolipid metabolism in rat models can use this ELISA kit from Assay Genie to quantify Alkaline Sphingomyelinase activity in tissue homogenates and related samples. Alk-SMase operates at neutral-to-alkaline pH, hydrolyzing sphingomyelin to release ceramide and phosphorylcholine, and is distinguished from the lysosomal acid sphingomyelinase by its pH optimum and subcellular targeting. In rodent research it is associated with intestinal mucosal turnover, hepatic lipid handling, atherosclerotic plaque biology, and ceramide-driven inflammatory signaling.

The kit is configured to accept tissue homogenates as the primary input and is validated specifically for rat samples, supporting side-by-side comparisons between treatment groups, organ systems, or time points. Each kit contains a pre-coated microplate along with the standards, detection antibodies, and buffers required to generate a calibration curve and quantify endogenous enzyme levels in user-prepared lysates, removing the need to source and validate individual immunoassay components in-house. Components should be stored as directed by the package insert to preserve the integrity of the standard curve, and the kit is intended for research use only.

Typical applications include profiling Alk-SMase in intestinal mucosal scrapings, liver and brain tissue lysates, and conditioned media from cultured rat cells. Pairing this measurement with parallel determination of acid sphingomyelinase activity or downstream ceramide species helps laboratories isolate the specific contribution of the alkaline isoform to an observed phenotype, while the rat-specific reactivity makes the kit valuable for preclinical studies in which cross-species extrapolation is a concern.
