Abstract Two-dimensional electrophoresis (2-DE) is an important technique in proteomics research. The 2-DE system for proteome of Monascus ruber was established by comparing and analyzing the infection caused by different kinds of mediums, lysis buffer and the condition of rehydration. By cultivating the Monascus ruber with YES for 6 days, extracting total protein by TCA-acetone, lysis buffer with 8 mol/L urea, 2 mol/L thiourea, 4 % CHAPS, 1 % DTT and 2 % Bio-lyte, an ideal 2-DE map with higher resolution and better legibility was obtained, which laid a foundation for the further studies on proteome of Monascus ruber.
