EIF2AK3 and neoplasm: A recent study showed that although the total time for fixation influenced the retention of phosphoprotein epitopes detected by immunoassays, the phosphorylated signaling proteins pAkt and pERK were relatively stable for 30 to 80 minutes post excision when formalin fixation was facilitated by thin diameter core cuts (approximately 2 mm) compared to thicker resected tumor tissues (median length = 29 mm) [73].
