Blood RNA/DNA tube to collect blood specimens quantified, inner of the tube with RNA/DNA special stabilizer, particularly suitable for the storage and transport of nucleic acid detection specimens. Characteristics: 1.The blood RNA/DNA tube prefilled with special reagent to quickly protect the RNA/DNA of specimens not to be degraded 2.The blood specimens can be stored for 3 days at 18-25°c, stored for 5 days at 2-8°c, keep stable for at least 50 months at -20°c to -70°c 3.Easy to use, only invert the blood RNA/DNA tube at 8 times after collection can intensive mixing of blood 4.Apply to fresh blood of humans and mammals, not suitable for timeworn blood & congealing blood as well as blood of poultry & other animals 5.Standardized collection, storage and transport of whole blood RNA/DNA detection specimens 6.Inner wall of the tube is special processing without RNase、DNase, ensure the primariness of nucleic acid detection specimens 7.Conducive to mass and rapid extraction of specimens, improve working efficiency of the laboratory
