The Mouse Alkaline Sphingomyelinase (ALK-SMASE) ELISA Kit is a specialized tool designed for the precise and accurate measurement of ALK-SMASE levels in mouse serum, plasma, and cell culture supernatants. This innovative kit provides exceptional sensitivity and specificity, ensuring dependable and consistent results for a variety of research applications.ALK-SMASE is a key enzyme involved in sphingomyelin metabolism, playing a critical role in various physiological processes such as lipid digestion, cell signaling, and membrane homeostasis. Dysregulation of ALK-SMASE activity has been linked to several diseases including metabolic disorders, neurodegenerative conditions, and inflammatory diseases, highlighting its importance as a potential biomarker for disease research and therapeutic development.
The Mouse Alkaline Sphingomyelinase (ALK-SMASE) ELISA Kit offers researchers a powerful tool for investigating the role of ALK-SMASE in health and disease, providing valuable insights into its physiological functions and pathological implications. With its superior performance and reliability, this kit is a valuable addition to any laboratory studying sphingolipid biology and related fields.
Matrices listed below were spiked with certain level of recombinant the index and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.

Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
