Virus Transport Medium is for the preservation and transportation of virus, chlamydia, mycoplasma and ureaplasma. 

The standard VTM is mainly composed of Hank's solution, gentamicin, fungal antibiotics, cryoprotectants, biological buffers, and amino acids. It can maintain the integrity of the virus in the temperature range from 2℃-30℃, and also reduce the speed of virus decomposition and increase the positive rate of virus isolation.
