Used to measure levels of CXCL1, also known as CINC-1 or KC, in biological samples from rats. This chemokine is a key marker of inflammation and neutrophil activation. The kit is commonly applied in research on inflammatory diseases such as arthritis, lung injury, sepsis, and ischemia-reperfusion injury. It helps evaluate the effectiveness of anti-inflammatory drugs and study immune responses in experimental models. The assay provides a sensitive and specific way to quantify protein levels in serum, plasma, and cell culture supernatants, supporting both academic and pharmaceutical research.
