NAT tube is widely used in collection, transportion and storage of venous
blood samples and sample treament before analysis. Mainly used for inspection
of nucleic acid amplification (Incl DNA of HBV, RNA of HCV,HIV) in clinics.
The additive of this tube is: EDTA.K2+Gel separator, sterilized by Gamma
radiation to ensure no DNAse, RNAse or Pyrogen. EDTA.K2 won't affect the
activity of Taq enzyme in nucleic acid test,gel separator can eliminate the
interference by hemoglobin of erythrocyte in the test of nucleic acid
inspection. Samples after separation can be stored at -70℃.
