The Amount of High Purity EDTA K2 Powder Reagent is Vary for Sizes of EDTA Anticoagulant Tubes
With the development of the medical industry, various test tube additives to assist blood testing have also followed, among which is the EDTA K2 anticoagulant added to the purple cap EDTA tube, compared with heparin, sodium citrate, potassium oxalate, etc. For anticoagulants, it is used more frequently, but it should be noted that the amount of EDTA is vary for sizes of EDTA tubes.
Application principle of EDTA K2 blood collection tube.
EDTA K2 is usually added to test tubes for blood routine testing, and the color of the cap is purple, but in nucleic acid test tubes, EDTA K2 is sometimes added as an anticoagulant. This is mainly because EDTA can complex calcium ions in the blood and inhibit the coagulation process. In addition, EDTA can also complex magnesium ions, which can inhibit nuclease that require the presence of magnesium ions to function, and can prevent nucleic acids from being destroyed or degradated by nuclease.

Amount of EDTA K2 in per millimeter blood
The amount of EDTA K2 added to the blood collection tube is actually determined according to the blood collection volume, and the blood collection volume is closely related to the size of the EDTA tube. The inner size of the EDTA tube is 75mm and 100mm. The amount of EDTA K2 to be added is determined according to the required blood volume. Generally, the content of EDTA K2 in each millimeter of blood is 1.5-2.2mg, and the middle value is 1.8mg/ml when preparing reagents.Since the produced EDTA K2 is in powder form, it is often required to be formulated into a solution for use.
The concentration of EDTA K2 solution
EDTA K2 is a water-soluble salt, it can be directly dissolved in water when preparing. But it should be noted that the concentration of the prepared EDTA solution should n
ot be too low or too high,the solubility may decrease when the temperature is lowered if the concentration is too high.Or lead to the precipitation of EDTA dipotassium crystals, and the high concentration of potassium ions may cause the risk of hemolysis of blood cells. Generally, 20 microliters of EDTA K2 solution is added to 2mL or 3mL of blood collection volume.
