Used in biomedical research to quantify levels of cystathionine β-synthase (CBS) in human samples such as plasma, serum, or tissue homogenates. This assay helps investigate conditions related to sulfur metabolism, including homocystinuria, cardiovascular diseases, and neurodegenerative disorders. It is also employed in studies exploring the role of CBS in hydrogen sulfide production, a key gasotransmitter involved in inflammation, vascular regulation, and cellular signaling. The kit supports high-throughput analysis in clinical labs and research settings for accurate, sensitive detection of CBS protein expression.
