Fluorescence analysis of HSP27 by flow cytometry. a L02 cells. b MCF-7 cells. The test group was incubated with N-PAMAM-IgG and QDs-IgG, PAMAM group as the control, which was only incubated with N-PAMAM-IgG to form a pseudocell for micromolecule protein detected by FCM. When the two curves almost overlap, it can be determined that there is no HSP27 in the sample; therefore, whether QDs-IgG is added or not, the fluorescence intensity will not change
