General description

Sorbitol Dehydrogenase (SDH) is an enzyme that catalyzes the interconversion of sorbitol and fructose. Elevated blood serum SDH levels indicate liver damage. Thus, SDH plays an important role in the diagnosis of liver disease, especially in combination with aminotransferases. SDH levels are also measured to evaluate diabetic complications such as proliferative diabetic retinopathy.

Application

Suitable for determining sorbitol dehydrogenase (SDH) activity in a number of biological samples such as plasma, serum, urine, tissue, and culture media.

Biochem/physiol Actions

Sorbitol dehydrogenase assay is a non-radioactive, colorimetric assay. It is based on the reduction of the tetrazolium salt MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide) in a NADH-coupled enzymatic reaction. The reduced form of MTT exhibits an absorption maximum at 565 nm and the increase in absorbance at 565 nm is directly proportional to the enzyme activity. This assay is based on a kinetic reaction. Sorbitol dehydrogenase (SDH) activity can be determined in a number of biological samples (e.g., plasma, serum, urine, tissue, and culture media).

Features and Benefits

Compatible with high-throughput handling systems.

Questions

  1. What are the recommended methods for homogenizing or lysing cells in a 96-well plate for the MAK317 Sorbitol Dehydrogenase assay kit? The manual advises against using proteolytic enzymes and suggests using a rubber policeman, which is not suitable for a 96-well plate. Are there any recommendations for a mild lysing buffer with minimal impact on the assay outcome? Additionally, is it possible and recommended to run the assay in the same 96-well plate, or is transferring the samples to a new plate necessary?

    1 answer
    1. The supplier advises that they have not yet validated any lysis buffers for use with cell samples in conjunction with this kit. Additionally, they recommend using an untreated, clear, flat-bottom plate for colorimetric measurements. Therefore, it would be preferable to transfer the samples to such a plate for running the assay.
