All bio analyses; such as, gene typing, gene expression analysis, biological protein analysis, screening of useful biomarkers, etc. need sample preparation, that is, extraction and purification of targeted substances from samples or removal of unneeded substances. PSS has automated sample pretreatment by using a "Column Tip" containing various commercially available carriers sealed in a uniquely-shaped pipetting tip.
Protein purification with open column, which has been used to carry out by manual operation, can be processed easily by using the Column Tip. Specifically, high level of automated protein purification is possible by simple and convenient operation in combination of prepackaged reagents needed for purification and "Purelumn" system.
