Antigen Specific T Cell Activation Assay Service

Antigen specific T cell activation is a central event in adaptive immunity, playing a pivotal role in infectious diseases, oncology, autoimmune disorders, and vaccine development. Creative Biolabs' Antigen Specific T Cell Activation Assay Service utilizes advanced technologies to deliver precise and reliable T cell functional analysis. Our service offers comprehensive characterization of T cell response dynamics with high sensitivity, high specificity, and customizable options, thereby aiding in-depth mechanistic insights, therapeutic efficacy evaluation, and accelerated drug and vaccine development.

Introduction

Antigen specific T cell priming denotes the cardinal immunological process in which naive T lymphocytes, upon ligation of their clonotypic T cell receptor (TCR) to cognate peptide–major histocompatibility complex (pMHC) ligands displayed on antigen-presenting cells, undergo co-stimulation–dependent clonal expansion, lineage specification and acquisition of effector competence. pMHC multimer–based strategies and indirect readouts, infer antigen specificity by quantifying surrogate activation signatures, including cytokine release, up-regulation of activation-induced surface molecules or proliferation are main assays to detect antigen specific T cell response.
