Fig. 5.
Correlation between protein level and quality parameters for five different proteins: GAPDH (G), Munc-18 (M), Syt1 (St), Rab3a (R), and Syntaxin (Sn). Only the correlation bars are shown for the tested proteins (dotted lines). (a) protein level and RIN; (b) protein level and pH; (c) protein level and PMI. No correlation develops in any case (R2<0.2) (see following table).
Prot level (r.u.) | GAPDH (G) | Munc-18 (M) | Syt-1 (St) | Rab 3A (R) | Synt (Sn)a |
---|---|---|---|---|---|
RIN | R2 = 0.0052 | R2 = 0.1743 | R2 = 0.0431 | R2 = 0.0026 | R2 = 0.04 |
pH | R2 = 0.0068 | R2 = 0.0193 | R2 = 0.1341 | R2 = 0.0413 | R2 = 0.0216 |
PMI | R2 = 0.0828 | R2 = 0.0834 | R2 = 0.1037 | R2 = 0.0334 | R2 = 0.0002 |
