Used in biomedical research to detect and quantify levels of SPTAN1 protein in human cell lysates or tissue extracts. This ELISA kit is particularly useful in neuroscience and cancer research, as SPTAN1 (also known as alpha-II spectrin) plays a role in maintaining cell membrane integrity and is involved in apoptosis and neurodegenerative processes. It enables researchers to study protein expression changes in conditions such as traumatic brain injury, stroke, Alzheimer's disease, and various cancers. The assay provides a sensitive and specific method for monitoring SPTAN1 in experimental models, supporting biomarker validation and mechanistic studies.
