Principles
Spider Biotin Target Fishing utilizes Spider biotin (a biotin derivative with special spatial structure) as an affinity tag to achieve efficient capture and enrichment of target proteins through specific interactions with target molecules.
Key Features
- High affinity: Spider biotin exhibits extremely strong affinity with its binding proteins (Kd at pM level)
- Low background noise: Special structural design significantly reduces non-specific binding
- Strong compatibility: Suitable for various sample types (cell lysates, tissue homogenates, serum, etc.)
- Simple operation: No complex chemical modification steps required; highly standardized workflow
Typical Applications
- Natural product target discovery and mechanism research
- Target protein screening for drug candidates
- Construction and analysis of protein-small molecule interaction networks
