30-color full spectrum flow cytometry panel for deep immunophenotyping of T cell subsets in murine tumor tissue.

This 30-color full spectrum flow cytometry panel was developed and optimized for in-depth analysis T cells immunophenotype in tumor microenvironment and peripheral lymphoid organs. The panel presented here first identify the main cell subsets including myeloid cells, B cells, NKT cells, γδ T cells, CD4+ T cells and CD8+ T cells. For CD4+ T cells or CD8+ T cells, the panel includes markers for further characterization by including a selection of activation status(CD44, CD62L, CD69, Ki67, CD127, KLRG1 and CXCR3), costimulatory/co-inhibitory molecules (ICOS, OX-40, PD-1, LAG3, TIM-3, CTLA-4 and TIGIT), pro-inflammatory/anti-inflammatory cytokines (IFN-γ, TNF-α and IL-10) and cytotoxic molecules (Perforin, Granzymes B and CD107a). The panel has been tested on the tumor infiltrating T cells and corresponding spleen T cells in B16-F10 murine melanoma models.

Nondestructive Transfer Strategy for High-Efficiency Flexible Perovskite Solar Cells.

Flexible perovskite solar cells (F-PSCs) have been developing fast with the power conversion efficiency (PCE) exceeding 19%. However, aiming at the high-efficiency F-PSCs, to get a desired perovskite morphology before and after glass-supportive device transfer is still a challenge. Herein, we thoroughly investigated the effect of adhesive materials of substrates on the perovskite film and the solar cell performance and developed a nondestructive F-PSC transfer method by introducing a double-side tape/protective film/epoxy binder. This nondestructive transfer strategy leads to a uniform morphology of perovskites, even after transfer process, yielding an enhanced PCE up to 16.55%.
