IL-2 is a 15 kDa four-α-helix cytokine, primarily secreted as a soluble molecule by activated T cells. IL-2 binds to the IL-2 receptor subunit CD25 with a dissociation constant of approximately 10⁻⁸ M.

The luciferase assay system serves as a core tool in gene regulation, cell viability, and high-throughput drug screening research, with its performance stability and sensitivity directly impacting the quality of experimental data.

Cell viability assay is a fundamental experimental technique in cell biology research, drug screening, and toxicity evaluation. Accurately, rapidly, and reproducibly assessing cell viability is crucial for understanding cellular physiological states, compound effects, and environmental influences.

Homogeneous time-resolved fluorescence technology is a novel detection platform that integrates the two core technologies of time-resolved fluorescence and fluorescence resonance energy transfer, and has wide applications in drug screening, life science research, and clinical diagnostics.

CD40 (also known as TNFRSF5) is a member of the tumor necrosis factor receptor superfamily, primarily expressed on antigen-presenting cells (such as dendritic cells and B cells). Its ligand, CD40L (also known as CD154 or TNFSF5), is mainly expressed on the surface of activated T cells. The interaction between CD40 and CD40L serves as a critical co-stimulatory signal in T cell-dependent immune responses, playing a vital role in B cell activation, antibody class switching, dendritic cell maturation, and the activation of cellular immunity.

In the fields of drug development, cancer research, and cell biology, the precise and sensitive detection of apoptosis is a critical step. As the most crucial executor proteins in the apoptosis pathway, the activation of Caspase-3/7 is a definitive marker of irreversible cell death. If you are seeking an optimal detection solution that requires no washing, is easy to operate, and is suitable for high-throughput screening, the **UA-Glo® Caspase 3/7 Assay Kit** is your ideal choice.

The core mission of fluorescent cell viability assays is to rapidly, accurately, and quantitatively determine the proportion of live and dead cells within a population.

UA-Blue SEAP Assay Kit offers doubled sensitivity and halved reaction time. This homogeneous, ready-to-use solution requires no cell lysis and is suitable for promoter studies, GPCR screening, and long-term dynamic monitoring.
