The heparinized blood from each animal was divided into two parts. A volume of 150 µl was designated for blood count and measured using an ABX Pentra 60 C+ hemoanalyzer (Horiba, Kyoto, Japan). The rest of the blood (200–300 µl) was lysed using EasyLyse™ (Dako, Glostrup, Denmark). The amount of cells in suspension was as determined by Turk’s solution (2% acetic acid; Sigma-Aldrich) using a hemocytometer chamber. Cells (5 × 105/100 µl) were marked with two panels of monoclonal antibodies. The first panel was delineated to detect T, B, and NK lymphocytes (CD3ϵ, CD4, CD8, CD19, and NK1.1). The second panel was designed for determination of monocytes and neutrophils (CD11b, F4/80, Ly6C, and Ly6G). The following monoclonal antibodies with fluorochromes for flow cytometry analysis were purchased from BioLegend (San Diego, CA, United States): anti-mouse CD3ϵ–FITC, CD4–BV421, CD19–PE, CD11c–BV421, CD45–APC/Fire™750, F4/80–PE, and from BD Bioscience: CD8–PECy7, CD11b–BV510, Ly6C–FITC, Ly6G–PECy7, and NK1.1–APC.

Flow cytometry was performed on primary cells obtained from explanted organs. Spleens, lungs, primary tumors, and livers were minced and enzyme digested with Liberase TL or TM (Roche), then filtered through a 70 μm cell strainer (Corning) to obtain a cell suspension. Whole blood was collected by cardiac puncture using a 23 guage needle (BD) attached to a 1 mL BD Luer-Lok syringe and mixed with 10 v/v% 25 mM EDTA (Life Technologies). Red blood cell lysis of whole blood, spleens, and lungs was performed with ACK Lysing Buffer (Life Technologies). Cells were pelleted by centrifugation at 400 × g for 5 minutes and resuspended in MACS buffer. NP+ cells were identified by Cy5.5 fluorescence signal. Nonspecific staining was blocked with anti-CD16/32 (Biolegend) and samples were stained for innate immune markers with anti-mouse CD45 AF700, F4/80 PE-Cy7, Ly6G PacBlue, Ly6C FITC (Biologend), and CD11b BV510 (BD Biosciences). For adaptive immune markers, samples were stained with anti-mouse CD45 AF700, CD4 V500, CD8 FITC, CD19 PacBlue, and CD49b PE-Cy7 (Biolegend). Stained samples were analyzed using the MoFlo Astrios Flow Cytometer or CytoFLEX (Beckman Coulter), and data were processed using FlowJo (BD) with the gating strategies shown in Figure S1.

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.
