Used for quantifying serine palmitoyltransferase (SPT) enzyme activity in human biological samples, this ELISA kit supports research into sphingolipid metabolism. It is commonly applied in studies related to metabolic disorders, neurodegenerative diseases such as hereditary sensory and autonomic neuropathies (HSAN), and conditions linked to sphingolipid imbalances. The kit enables high-throughput screening in clinical research and drug development, allowing assessment of SPT modulation by potential therapeutics. It is also useful in biomarker discovery and validation workflows where altered SPT activity serves as an indicator of cellular stress or disease progression.
