Overview

The EasySep™ Mouse CD8a Positive Selection Kit II is designed to isolate CD8a+ cells from single-cell suspensions of splenocytes or other tissues by positive selection. Desired cells are targeted with antibody complexes recognizing CD8a and dextran-coated magnetic particles. Labeled cells are separated using an EasySep™ magnet without the use of columns. Cells of interest remain in the tube while unwanted cells are poured off.

This product replaces the EasySep™ Mouse CD8a Positive Selection Kit (Catalog #18753) for even faster cell isolations and does not result in the labeling of isolated cells with PE.
Advantages:
• Fast and easy-to-use
• Up to 98% purity
• No columns required
• Isolated cells are not fluorochrome labeled

Abstract

The costimulation of immune cells using first-generation anti-4-1BB monoclonal antibodies (mAbs) has demonstrated anti-tumor activity in human trials. Further clinical development, however, is restricted by significant off-tumor toxicities associated with Fc$\gamma$R interactions. Here, we have designed an Fc-free tumor-targeted 4-1BB-agonistic trimerbody, 1D8N/CEGa1, consisting of three anti-4-1BB single-chain variable fragments and three anti-EGFR single-domain antibodies positioned in an extended hexagonal conformation around the collagen XVIII homotrimerization domain. The1D8N/CEGa1 trimerbody demonstrated high-avidity binding to 4-1BB and EGFR and a potent in vitro costimulatory capacity in the presence of EGFR. The trimerbody rapidly accumulates in EGFR-positive tumors and exhibits anti-tumor activity similar to IgG-based 4-1BB-agonistic mAbs. Importantly, treatment with 1D8N/CEGa1 does not induce systemic inflammatory cytokine production or hepatotoxicity associated with IgG-based 4-1BB agonists. These results implicate Fc$\gamma$R interactions in the 4-1BB-agonist-associated immune abnormalities, and promote the use of the non-canonical antibody presented in this work for safe and effective costimulatory strategies in cancer immunotherapy.
