The SPR (Surface Plasmon Resonance) binding assay is a powerful technique used to study molecular interactions in real-time without the need for labeling. It is commonly employed to analyze the kinetics, affinity, and specificity of interactions between biomolecules, such as protein-protein, protein-DNA, or protein-small molecule interactions. Principle of SPR Binding Assay In an SPR assay, …

Primary cells refer to cells that are isolated or harvested directly from living tissue or organs. Primary cells closely mimic the physiological state of cells in vivo and are expected to maintain their in vivo functions under optimal conditions for a short period of time. The primary cells present several advantages over cell lines, including a …
OX40 (CD134), a key costimulatory molecule in the tumor necrosis factor receptor superfamily, is crucial for enhancing T cell function and driving anti-tumor immunity, making it a significant focus in cancer immunotherapy research. Structure and Costimulatory Mechanism (i) Expression Pattern OX40 is a transmembrane glycoprotein expressed on activated T cells (peaking 48-72 hours post-activation), but …
