It must be used in conjunction with our company's receptor microspheres to form a complete homogeneous chemiluminescent detection system, enabling wash-free, high-sensitivity, rapid quantitative analysis, suitable for immunoassays, protein–protein interactions, small-molecule detection, and the development of in vitro diagnostic reagents.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Particle size: 200 nm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Surface functional group: Streptavidin (SA)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Appearance: Uniform suspension\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Matching excitation: 680 nm laser\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e• Signal mechanism: Generates singlet oxygen, activating the receptor microspheres to emit light at 610 nm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e.
