1, Dual reagent composition architecture of LDH detection kit
The LDH detection kit adopts a two-component design of independent reagent I and reagent II, both of which use HEPES as the basic biological buffer to ensure that the detection system maintains a stable pH environment during the reaction process, providing suitable conditions for enzymatic reactions.
HEPES powder
The composition of reagent I revolves around the initiation of LDH reaction and environmental optimization. In addition to HEPES, it also includes metal ion complexes, LDH reaction substrates, surfactants, LDH enzyme activators, preservatives, and water. Among them, metal ion complexes can regulate the ion environment in the reaction system, avoiding interference ions from affecting the detection results; The substrate provides a specific target for LDH to ensure directed reaction; Surfactants can enhance the solubility and dispersibility of each component in the reagent, activators can increase the catalytic activity of LDH, and preservatives can prolong the storage shelf life of the reagent.
The components of reagent II focus on the signal generation of LDH catalyzed reactions, also buffered with HEPES, supplemented with nicotinamide adenine dinucleotide oxidation state (NAD+), surfactants, and preservatives. NAD+, as a coenzyme in LDH catalyzed reactions, is converted to a reduced state (NADH) during the reaction process, and its concentration changes can be reflected in LDH activity through absorbance detection at specific wavelengths; The role of surfactants and preservatives is consistent with that of reagent I, ensuring the solubility and storage stability of the reagent, respectively.
2, Core performance advantages of dual reagent kit
The dual reagent design based on HEPES buffer system brings multiple performance improvements to LDH detection. In terms of anti-interference ability, the dual reagent mode can effectively avoid non-specific reactions caused by enzymes and small molecules in the sample through stepwise reactions. At the same time, the components in the reagent can reduce the influence of sample turbidity on absorbance detection, ensuring that the detection results are not affected by interfering factors.
In terms of detection accuracy and stability, HEPES buffer can stably maintain the pH value of the reaction system, avoiding the influence of pH fluctuations on LDH activity and reaction process. With precise substrate and coenzyme ratios, the detection results have good accuracy. At the same time, the components of the reagent kit have been optimized for stability and can maintain activity stability for a long time under specified storage conditions, ensuring the consistency of test results from different batches.
In addition, the kit also has the characteristic of a wide linear testing range, which can cover the commonly used LDH activity concentration range in clinical practice, reducing the need for repeated testing due to sample concentrations exceeding the linear range. In terms of operational convenience, there is no need to pre dilute the sample during the detection process, which can be directly applied to fully automatic biochemical analyzers, simplifying the operation process while shortening the detection time, meeting the demand for rapid clinical reporting.
3, Clinical application scenarios and value
With stable performance and convenient operation, the LDH detection kit containing HEPES is suitable for clinical testing scenarios in medical institutions at all levels, and can be used for auxiliary diagnosis and disease monitoring of various diseases such as liver function injury, myocardial disease, and hematological diseases. For example, in the diagnosis and treatment of liver disease patients, detecting serum LDH activity can assist in evaluating the degree of liver cell damage; In the monitoring of the course of myocardial infarction patients, changes in LDH activity can serve as a reference indicator for disease progression.
The application of this reagent kit not only provides reliable detection data support for clinical practice, but also reduces the workload of testing personnel by simplifying operations and improving efficiency, meeting the requirements of modern clinical testing for accuracy and efficiency, and providing strong technical support for disease diagnosis and treatment.
