From: The lyophilized chloroplasts store synthetic DARPin G3 as bioactive encapsulated organelles
Characterization of HER2 binding of chloroplast-made DARPin G3 from fresh and lyophilized leaves and chloroplasts of tobacco transplastomic plants by flow cytometry in human HER2-positive (SKBR3) and human HER2-negative breast cancer cells (MDA-MB-231). Cells incubated with PBS or anti-His-tag antibody followed by FITC-conjugated antibody were used as unstained and omission controls, respectively. Data from representative experiments are shown
