For tissue samples. Must it be fresh samples? Can frozen samples be tested?

Source: Elabscience®Published: Mar 04,2024

It is recommended to use fresh samples as far as possible. If the samples are frozen, the results may be low or undetectable.The longer the frozen storage time, the greater the impact on the results. Generally, the sample should not be stored at -80℃ for more than one month. If the frozen storage time is more than one month, it is not recommended to use.
