Table 1 Correlation between brain bank tissue quality parameters and number of detected postsynaptic density proteins

From: Human post-mortem synapse proteome integrity screening for proteomic studies of postsynaptic complexes

Parameter Spearman r p value (two-tailed)
PM Interval (n = 28) 0.01079 0.9566 (n.s.)
pH (n = 25) −0.075 0.1193 (n.s.)
RNA Integrity Number (RIN) (n = 20) 0.1193 0.6163 (n.s.)
Intensity of GluN2B Band 1/Band 2 (n = 28) 0.5905 0.0009 (***)
Intensity of GluN2B Band 1/Band 3 (n = 28) −0.01091 0.956 (n.s.)
Intensity of GluN2B Band 1/Band 2 + Band 3 (n = 28) 0.4831 0.0092 (**)
  1. Number in brackets indicates the number of tissue samples (out of 28) with a value for that particular parameter; n.s. not significant; ***p < 0.001 and **p < 0.01.
