| Abstract: | Objective]To recover less abundant protein with the MWT less than 10 000 Da with an effective electroeluting method.Methods]The improved SDS-PAGE and electroeluting methods were used to separate and purify the small molecular protein,and SELDI technology was used to detect the recovered protein.Results]The results of SELDI showed that less abundant proteins with the MWT less than 10 000 Da was effectively separated and recovered by improved SDS-PAGE and electroeluting methods.Conclusion]The improved electroeluting method is not only effective to recover the less abundant protein with the MWT less than 10 000 Da,but also favourable to identify these proteins. |
