Table 1 Rate of degradation of 28S and 18S rRNA in bovine skeletal muscle, adipose tissue and liver and the statistics of the slope from the exponential regression model

From: Long-term stability of RNA in post-mortem bovine skeletal muscle, liver and subcutaneous adipose tissues

  Half-life R 2 P < Slope SE
28S rRNA      
Skeletal muscle (48) 141 h (5.9 d) 0.91 0.001 -0.00491 0.00023
Adipose tissue (48) 125 h (5.2 d) 0.66 0.001 -0.00557 0.00060
Liver (32) 21 h (0.9 d) 0.75 0.001 -0.03309 0.00347
18S rRNA      
Skeletal muscle* - - - - -
Adipose tissue (48) 216 h (9.0 d) 0.45 0.001 -0.00321 0.00053
Liver (32) 69 h (2.9 d) 0.19 0.05 -0.01009 0.00376
  1. (numbers in parenthesis is the n = number of observation used for half-life calculation, *due to the non-significant (P > 0.05) change in the intensity of 18S rRNA of the skeletal muscle after 22 days post-mortem, exponential model failed to fit the 18S data)
