AF 488 Streptavidin is a green-fluorescent probe (Ex/Em: 495/519 nm) with high affinity for biotin-labeled targets. It delivers bright, stable signals, making it ideal for sensitive and specific detection in fluorescence-based assays.
Key Features:
- High Affinity: Strong, specific binding to biotin-labeled molecules.
- Bright Fluorescence: Intense green signal for easy detection.
- Photostability: Resistant to photobleaching for long imaging sessions.
- Versatile Use: Compatible with various detection systems.
Applications:
- Immunohistochemistry (IHC): Protein localization in tissues.
- Immunocytochemistry (ICC): Protein detection in cultured cells.
- Flow Cytometry: Cell population analysis.
- In Situ Hybridization (ISH): Nucleic acid detection.
- ELISA: Fluorescence-based assay enhancement.
The recommended concentration range for use is 0.5-10 µg/mL. Avoid using biotin-containing solutions (some serums, RPMI 1640, etc.) as diluents.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
