A Method Suitable for Total Protein Extraction from Wood Forming Tissue of Pinus koraiensis
Total protein extraction method should be adjusted for get higher quality product for special material. We optimized the protocols and extracted total proteins from P. koraiensis adopt TCA-acetone, TCA-acetone contains β-mercaptoethanol, methanol and protein extraction kit respectively. Then we compared extracts from these methods using SDS-PAGE. The results show that there are no obvious differences between TCA, TCA-2ME and Methanol, which all have better bands. In contrast, extracts from protein extraction kit had ambiguous bands. We also found that it should take about eight hours at least for precipitate of mixtures of samples and extraction solutions. We think optimized TCA-acetone is an idea method for protein extraction from P. koraiensis.
