Activin receptor IIA and activin receptor IIB both belong to the transforming growth factor-β receptor family. They are highly similar in amino acid sequence and overall structure, and both can recognize and bind multiple ligands such as activin, growth differentiation factor 11, and myostatin.

Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) is a highly sensitive biophysical technique that combines time-resolved fluorescence detection with the principle of Förster resonance energy transfer.

The CyQuantiFluor™ Cell Viability Assay Kit is a homogeneous detection kit based on DNA-specific fluorescent dyes. Its core principle is: DNA-binding dyes can penetrate the membranes of live cells and bind to nuclear DNA to produce strong fluorescence, with fluorescence intensity proportional to the number of viable cells; background-shielding dyes cannot enter live cells but can block fluorescence signals from DNA released by dead cells and extracellular DNA, ensuring detection specificity. This method does not rely on cellular metabolic state and directly quantifies the DNA content of live cells, offering advantages such as simple operation (one-step addition), high signal-to-noise ratio, and excellent stability. It is suitable for tumor cell proliferation assays and high-throughput compound screening.

Cell viability and proliferation assays are among the most fundamental and essential experimental techniques in cell biology, drug screening, and toxicology research. Traditional methods such as MTT and CCK-8 rely on the activity of intracellular metabolic enzymes to convert substrates into colored or fluorescent products, thereby indirectly reflecting the number of viable cells.
