Creatinine is commonly measured in urine and is a key benchmark for the normalization of a variety of urinary biomarkers. Serum creatinine levels, however, are a useful indicator of renal function and abnormal levels have been implicated in diabetes, cardiovascular, and circulatory diseases.…

Catalase is an ubiquitous antioxidant enzyme that is present in most aerobic cells. It is involved in the detoxification of H2O2, a ROS that is a toxic product of both normal aerobic metabolism and pathogenic ROS production. Cayman’s Catalase Assay utilizes the peroxidatic function of…

Cayman’s GSH Assay utilizes a carefully optimized enzymatic recycling method for the quantification of GSH in a 96-well microplate format. It measures both GSH and GSSG to reflect total glutathione in a sample. The kit can also be used to measure only GSSG by following an alternative…

11-KT is a second key androgenic steroid found in fish. It occurs in males together with testosterone in amounts which vary from less than 1 ng/ml to as much as 50-100 ng/ml, depending on the species and the stage of the reproductive cycle.
