Used in biomedical research to detect and quantify levels of signal regulatory protein alpha (SIRPA) in rat samples. Commonly applied in immunology and cancer research to study immune cell signaling, macrophage activity, and tumor microenvironment interactions. Enables researchers to assess SIRPA expression in experimental models, supporting studies on immune checkpoint pathways and therapeutic development. Suitable for use with serum, plasma, and cell lysates. Provides a reliable, sensitive, and high-throughput method for protein measurement in preclinical studies.
