1. Western blotting: Wash with PBS, add electrophoresis sample buffer directly to the stretch chamber, then collect the cell lysate with a cell scraper.


2. Immunoprecipitation: Wash with PBS, add cell solubilizer directly to the stretch chamber, then collect the cell lysate with a cell scraper.

3. mRNA:Wash with PBS suitable for RNA, add cell solubilizer directly to the stretch chamber, then collect the cell lysate with a cell scraper.
