● Purpose: it is applicable to the collection, transportation and storage of venous blood samples for nucleic acid detection, as well as sample processing before analysis. It is mainly used for nucleic acid amplification detection in clinic.

● This kind of blood collection additive is edta.k2 and separating gel. Adopt edta K2 will not affect the activity of Taq enzyme in the nucleic acid detection experiment, and the separation gel can effectively eliminate the interference . of hemoglobin in red blood cells to the nucleic acid detection experiment. The separated samples can be frozen at -70 °C.
