Single cell suspensions from spleens and lymph nodes were prepared as described.6 (link) TIL were isolated from pooled tumors as described.26 (link) All flow cytometry experiments were performed at least 3 times. Single cell suspensions were incubated with mouse Fc receptor binding inhibitor for 10 minutes before staining with antibodies to CD45 (clone 30-F11), CD3 (clone 145-2C11), CD4 (clone GK1.5), CD8 (clone 53-6.7), CD19 (clone eBio1D3), CD86 (clone GL1), CD11b (clone M1/70), Gr-1 (clone RB6-8C5), CD69 (clone H1.2F3), CD44 (clone IM9), CD62L (clone MEL-14), and CD11c (clone N418; all from eBioscience, San Diego, CA) for 30 minutes. Flow cytometry was performed using FACS Calibur (BD Biosciences) and the lymphocyte population was selected by gating CD45+ cells. The data were analyzed using Flow Jo software (Tree Star, Ashland, OR). For tetramer staining, 10 μL of PE labeled HLA-A*02:01 Human HPV16 E7 tetramer (NIH Tetramer Core Facility) was added to 200 μL mouse lymphocyte suspension (1×106 cells per tube). After incubation for 30 minutes, cells were centrifuged and resuspended in phosphate-buffered saline with 1% paraformaldehyde and then analyzed by flow cytometry. PE labeled HLA-A*02:01 human mesothelin tetramer (NIH Tetramer Core Facility) was used as control.

Cells were surface-stained in PEB buffer (PBS supplemented with 0.5% BSA and 2mM EDTA) for 20–30 min on ice. Multiparametric flow cytometric analyses were performed on a LSRII equipped with FACS Diva 6.1 software (BD Biosciences) and analysed with FlowJo software (Tree Star). Dead cells were excluded by FSC, SSC and 4’,6-diamino-2-phenylindole (DAPI, Sigma) staining. Cell sorting experiments were performed on Aria Cell Sorter (BD Biosciences). HSCs measured by flow cytometry were defined as: Lineage Sca1+ cKit+ Flt3. Antibodies used: anti-mouse mABs Sca1/Ly-6A/E (clone D7, ebioscience), CD117/cKit (clone ZB8, Biolegend), CD135/Flt3 (clone AZF10, ebioscience), lineage cocktail (BD Pharmingen cat# 559971), CD41 (clone RMV-7, ebiosicence), CD45 (clone 30-F11, ebioscience), Ter119 (clone TER-119, ebioscience), CD31 (clone MEC13.3, ebioscience), Gr-1 (clone RB6-8C5, ebioscience), CD11b (M1/70, ebioscience), CD115/c-fms (clone AFS98, ebioscience), F4/80 (BM8, ebioscience), and BrdU (clone BU20A, BD Pharmingen with BrdU flow kit reagents for fixation and permeabilization).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
