Effect, dosage, and preservation method of dipotassium edta anticoagulant

    Ethylenediaminetetraacetic acid dipotassium CAS is 25102-12-9, which is a recommended treatment reagent by the International Committee on Hematology. It not only has good anticoagulant effects, but also has little impact on blood cell composition, ensuring that the morphology of red blood cells, white blood cells, and platelets does not change, and has strong stability. Based on these obvious advantages, it has become an indispensable processing reagent in clinical medicine. Below, we will introduce it in detail.

    1、 The effect of potassium ethylenediaminetetraacetic acid anticoagulant

As a calcium chelating agent, due to the presence of calcium ions in the blood, it can chelate with calcium ions. This decrease in calcium ion content will prevent endogenous or exogenous coagulation processes, thereby achieving the goal of anti blood coagulation. It is suitable for various biochemical tests. But precisely because of its anticoagulant effect, it cannot be used for the determination of metal substances in plasma and coagulation experiments, otherwise the accuracy of the experimental results cannot be guaranteed.

    2、 Concentration addition of potassium ethylenediaminetetraacetic acid anticoagulant

    Although blood collection vessels containing potassium ethylenediaminetetraacetate are currently widely used, the amount of concentration added remains a problem. It is generally recommended to collect 0.5-2ml of blood in test tubes, but in the actual blood collection process in hospitals, it may sometimes exceed the standard blood collection range, which may lead to an imbalance in the ratio of blood samples to potassium ethylenediamine tetraacetate anticoagulant, leading to slight coagulation of the sample, instrument blockage, or inaccurate analysis results. Therefore, in response to this phenomenon, relevant researchers have provided the most appropriate standard concentration range of potassium ethylenediaminetetraacetate at 2.24mg/mL.

    3、 Preservation of potassium ethylenediaminetetraacetic acid anticoagulant

    The finished product of potassium ethylenediaminetetraacetic acid sold as powder is easily affected by moisture when dissolved in water, so its storage method and quality are closely related. If it is necessary to prepare it into a solution, be sure to immediately remove and seal it, and do not place it in an excessively humid environment. If the solution is in a prepared state, it needs to be stored in a high-density glass bottle to ensure that the storage device is free of impurities, reduce the possibility of reaction between potassium ethylenediaminetetraacetate and other substances, and pay attention to the surrounding environment being dry and the temperature not being too high.

    As an advantageous manufacturer of potassium ethylenediaminetetraacetic acid anticoagulant, Desheng has clear specifications for its key indicators such as pH value, solubility, molecular weight, and stable quality, which can be used by customers to complete different experiments.
