Product Introduction

Glutathione thiol transferase (GST, 2.5.1.18) is generally formed by the aggregation of two subunits of 25-27kDa in a homologous or heterologous manner (with an isoelectric point of pH4-5). The N-terminal of its subunit has a conserved serine/tyrosine (Ser/Tyr) residue, and its hydroxyl group forms a hydrogen bond with the thiol group of glutathione (GSH), which is a specific binding site for GSH.

GST is a group of multifunctional isoenzymes widely distributed in various organisms. It is a group of enzymes related to the detoxification function of the liver, mainly present in the liver, and in trace amounts in tissues such as the kidneys, small intestine, testes, ovaries, etc. Its main function is to catalyze the coupling of electrophilic groups of certain endogenous or foreign harmful substances with the thiol group of reduced glutathione, increasing its hydrophobicity and making it easy to cross cell membranes, And after being decomposed, it is discharged from the body to achieve the purpose of detoxification. Due to the abundance of GST in the cytoplasm of liver cells, enzymes are rapidly released into the bloodstream when liver cells are damaged, leading to an increase in serum GST activity.

GST is often used in the construction of highly efficient expression vectors in genetic engineering, so as to co express with some difficult proteins as molecular chaperones, so as to achieve a soluble expression; In addition, GST antibodies are often used for Western Blot and other experiments to detect whether gene co expression is achieved, so studying them is of great significance.




The relationship between enzyme preparations, new Trinder's reagents, and Good's buffer

There are many principles of in vitro diagnostic kits, and the most common one is a diagnostic kit based on the Trinder reaction principle (also known as enzyme method), which can be used for the detection of uric acid, creatinine, blood sugar, cholesterol, triglycerides, etc. in blood tests. This diagnostic kit typically includes important components such as enzymes, new Trinder's reagents, and Good's buffer.

By adding the new Trinder's reagent to the test substance, a color reaction occurs, and the value of the test item is calculated through absorbance measurement. For example, the values of blood sugar and uric acid in serum. The new Trinder's reagent has the advantages of high water solubility, UV absorption of color reaction products>540nm, wide pH range requirements for color reactions, and high sensitivity for color reactions.
 

The use of enzyme preparations in the Trinder reaction is due to the presence of too many substances in the serum, and the specificity of enzyme preparations. For example, adding glucose oxidase will only catalyze the oxidation of blood sugar to generate hydrogen peroxide, without catalyzing the oxidation of uric acid and other substances present in the serum, ensuring the accuracy of the detection results as much as possible. However, pH value has a significant impact on enzyme activity, and each enzyme has its own high activity pH range. At this point, Good's buffer is needed to adjust the pH value.

Different Good's buffers can provide suitable buffer intervals for different enzymes. Good's buffer has the advantages of high water solubility, bottom cell membrane permeability, stable acid-base dissociation constant, low metal chelating ability, high chemical stability, etc. In summary, enzyme preparations, new Trinder's reagents, and Good's buffer complement each other in the diagnostic kit, making corresponding contributions to the precise detection of diseases.
