    L-xylulose reductase Antibody (18-Q) is a mouse monoclonal IgG1 kappa light chain antibody that detects L-xylulose reductase of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Anti-L-xylulose reductase antibody (18-Q) is available as the non-conjugated monoclonal isotype antibody. L-xylulose reductase (XR), also known as kidney dicarbonyl reductase (kiDCR) or sperm surface protein P34H, is a 244 amino acid protein belonging to the short-chain dehydrogenases/reductases family. This enzyme plays a crucial role in the renal tubules by catalyzing the NADPH-dependent reduction of various sugars, including L-xylulose, to the osmolyte xylitol, which is vital for preventing osmotic stress in kidney cells. L-xylulose reductase functions as a homotetramer to enhance enzymatic efficiency and is predominantly expressed in the kidney, liver, and epididymis. A partial deficiency in L-xylulose reductase can lead to essential pentosuria, characterized by the presence of L-xylulose in the urine. Normal red blood cells contain two isozymes of L-xylulose reductase, while those from patients with pentosuria exhibit only one isozyme. Given L-xylulose reductase′s involvement in the uronate cycle of glucose metabolism, this enzyme has been implicated in managing long-term complications associated with diabetes, making L-xylulose reductase a significant target for research and therapeutic interventions.
