  • Product overview

    Succinyl-CoA Synthetase Activity Assay Kit (Colorimetric) (ab196989) is an assay where Succinyl-CoA Synthetase (SCS) converts succinate into succinyl-CoA in the presence of ATP and CoA. Succinyl-CoA reacts with the SCS Developer to form a colored product with strong absorbance at OD=450 nm. This kit is simple to use and high throughput adaptable.

    It can detect less than 0.1 mU of Succinyl-CoA Synthetase activity in a variety of samples.

  • Notes

    Succinyl-CoA Synthetase (SCS, also called Succinyl-CoA ligase, Succinate Thiokinase) (EC is a critical enzyme in the citric acid cycle (TCA) and an important metabolic intermediate for porphyrin, heme and ketone body biosynthesis. It is located in the mitochondrial matrix and is a heterodimer composed of one alpha and one beta subunit.

    In humans, Succinyl-CoA Synthetase deficiency causes the build-up of lactic acid leading to lactic acidosis, which can be fatal in infants. Measurement and analysis of SCS activity is useful for both mechanistic studies as well as for diagnostic purposes.

  • Typical NADH Standard Curve using colorimetric reading.

  • Succinyl-CoA Synthetase activity measured in mitochondria isolated from bovine heart, yeast (P. pastoris) and MCF-7 cells and in Jurkat cell lysate. The graph also shows data from the SCS Positive Control included in the kit and Blank background baseline.

  • Succinyl-CoA Synthetase specific activity in mitochondria prepared from yeast (P. pastoris, 1.14 μg), bovine heart (1.1 μg) and MCF-7cells (0.5 μg), and in Jurkat cell lysate (25 μg).
