Factor Xa Chromogenic Substrate by Molecular Depot is a high purity chromogenic substrate for factor Xa protease assays. Cleavage releases para-nitroaniline, which absorbs at 405 nm, so activity is read as absorbance over time. It is used to measure factor Xa activity, to assay heparin and direct factor Xa inhibitors and in coagulation research. Each unit contains 5 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
