Table 1 Comparison of blood samples collected in PAXgene and in Tempus tubes

From: Human blood RNA stabilization in samples collected and transported for a large biobank

A) Adult blood
Storage at RT (days) RIN value OD 260/280 ratio OD 260/230 ratio Number of tubes
PAXgenes tube
0 8.0 ± 0.3 2.12 ± 0.02 1.56 ± 0.31 5
2 8.0 ± 0.3 2.10 ± 0.03 1.56 ± 0.62 5

7 8.2 ± 0.3 2.09 ± 0.03 1.42 ± 0.70 5
Average 8.10 ± 0.3 2.11 ± 0.02 1.48 ± 0.61* 20
Tempus tubes

B) Cord blood
  PAXgene (n = 8)   Tempus (n = 7)  
RIN value 8.1 ± 0.2   8.0 ± 0.2  
OD 260/280 ratio 2.1 ± 0.1   2.0 ± 0.3  
OD 260/230 ratio 1.6 ± 0.5*   2.0 ± 0.8  
  1. Notes. * RNA from PAXgene tube-collected samples have significantly lower OD 260/230 ratio compared to RNA from Tempus tube-collected samples, p < 0.05. The cord blood samples were transported to NIPH (lab) within one day. n = number of tubes.
