EasySep™ Mouse CD8+ T Cell Isolation Kit
17.5-Minute cell isolation kit using immunomagnetic negative selection
New format, same high quality! You may notice that your kit contents and packaging look slightly different from previous orders. We are currently updating the format of select EasySep™ Mouse kits to include a Mouse FcR blocker instead of Normal Rat Serum. With this change, all components will now be shipped in a single package, while providing the same cell isolation performance as before.

Detecting Tumor Antigen-Specific T Cells via Interaction-Dependent Fucosyl-Biotinylation.
Cell 2020 nov
Abstract
Re-activation and clonal expansion of tumor-specific antigen (TSA)-reactive T cells are critical to the success of checkpoint blockade and adoptive transfer of tumor-infiltrating lymphocyte (TIL)-based therapies. There are no reliable markers to specifically identify the repertoire of TSA-reactive T cells due to their heterogeneous composition. We introduce FucoID as a general platform to detect endogenous antigen-specific T cells for studying their biology. Through this interaction-dependent labeling approach, intratumoral TSA-reactive CD4+, CD8+ T cells, and TSA-suppressive CD4+ T cells can be detected and separated from bystander T cells based on their cell-surface enzymatic fucosyl-biotinylation. Compared to bystander TILs, TSA-reactive TILs possess a distinct T cell receptor (TCR) repertoire and unique gene features. Although exhibiting a dysfunctional phenotype, TSA-reactive CD8+ TILs possess substantial capabilities of proliferation and tumor-specific killing. Featuring genetic manipulation-free procedures and a quick turnover cycle, FucoID should have the potential of accelerating the pace of personalized cancer treatment.
Pharmacokinetic tuning of protein-antigen fusions enhances the immunogenicity of T-cell vaccines.
Nature biomedical engineering 2020 jun
Abstract
The formulations of peptide-based antitumour vaccines being tested in clinical studies are generally associated with weak potency. Here, we show that pharmacokinetically tuning the responses of peptide vaccines by fusing the peptide epitopes to carrier proteins optimizes vaccine immunogenicity in mice. In particular, we show in immunized mice that the carrier protein transthyretin simultaneously optimizes three factors: efficient antigen uptake in draining lymphatics from the site of injection, protection of antigen payloads from proteolytic degradation and reduction of antigen presentation in uninflamed distal lymphoid organs. Optimizing these factors increases vaccine immunogenicity by up to 90-fold and maximizes the responses to viral antigens, tumour-associated antigens, oncofetal antigens and shared neoantigens. Protein-peptide epitope fusions represent a facile and generalizable strategy for enhancing the T-cell responses elicited by subunit vaccines.
Lymphatic endothelial cells prime na\ive CD8+ T cells into memory cells under steady-state conditions."
Nature communications 2020 jan
Abstract
Lymphatic endothelial cells (LECs) chemoattract na{\{i}}ve T cells and promote their survival in the lymph nodes and can cross-present antigens to na{\"{i}}ve CD8+ T cells to drive their proliferation despite lacking key costimulatory molecules. However the functional consequence of LEC priming of CD8+ T cells is unknown. Here we show that while many proliferating LEC-educated T cells enter early apoptosis the remainders comprise a long-lived memory subset with transcriptional metabolic and phenotypic features of central memory and stem cell-like memory T cells. In vivo these memory cells preferentially home to lymph nodes and display rapid proliferation and effector differentiation following memory recall and can protect mice against a subsequent bacterial infection. These findings introduce a new immunomodulatory role for LECs in directly generating a memory-like subset of quiescent yet antigen-experienced CD8+ T cells that are long-lived and can rapidly differentiate into effector cells upon inflammatory antigenic challenge."""
