Used in biomedical research to quantitatively detect hnRNPA1 protein levels in cell lysates, tissue extracts, and biological fluids. Enables studies on RNA metabolism, gene expression regulation, and splicing mechanisms. Widely applied in neuroscience research to investigate roles of hnRNPA1 in neurodegenerative diseases such as ALS and frontotemporal dementia. Supports biomarker discovery and validation in cancer research due to hnRNPA1's involvement in tumor progression and cellular stress responses. Facilitates high-throughput screening in drug development targeting RNA-binding proteins.
