Home Can Total RNA Extraction Miniprep System be used to extract RNA from blood sample?

This System Is Not Suitable For Samples Of Liquid Form Such As Whole Blood. However, It Can Extract RNA From Buffy Coat. This System Cannot Be Used For Liquid Samples Because Liquid In Sample Will Dilute Out RX Buffer, Thus Reducing Its Lysis And RNase Inactivating Ability. Since Only White Blood Cells Contain RNA, One Should Only Use Buffy Coat For RNA Extraction. Buffy Coat For RNA Extraction Should Be Prepared From Fresh Blood Sample.
