Overview

Easily isolate highly purified mouse CD45+ tumor-infiltrating leukocytes (TILs) by immunomagnetic positive selection using the EasySep™ Mouse TIL (CD45) Positive Selection Kit. This kit has been optimized for use on single-cell suspensions of solid mouse tumors, including tumors induced by implantation of 4T1, B16-F10, and CT26.WT cell lines into syngeneic mice. Due to the heterogeneity of mouse tumors, this kit may require optimization. Widely used in published research for more than 20 years, EasySep™ combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system.

In this EasySep™ positive selection procedure, desired cells are labeled with antibody complexes recognizing CD45 and magnetic particles. Labeled cells are separated using an EasySep™ magnet and by simply pouring or pipetting off the unwanted cells. The cells of interest remain in the tube. Following magnetic cell isolation, the desired CD45+ TILs are ready for downstream applications such as flow cytometry, culture, and cell-based experiments.

Figure 1. EasySep™ Mouse TIL (CD45) Positive Selection Kit

Tumors were induced by B16-F10, 4T1, or CT26.WT cell lines and dissociated into single-cell suspensions. CD45+ TILs were isolated from single-cell suspensions at various start concentrations using the purple EasySep™ Magnet. (A) Starting with a B16-F10 tumor single-cell suspension at 1 x 10^8 cells/mL, the purities of the start and final isolated fractions are 14.8% and 95.2%, respectively. (B) Starting with a 4T1 tumor single-cell suspension at 4 x 10^7 cells/mL, the purities of the start and final isolated fractions are 37.6% and 93.0%, respectively. (C) Starting with a CT26.WT tumor single-cell suspension at 2.5 x 10^7 cells/mL, the purities of the start and final isolated fractions are 32.3% and 84.6%, respectively.
