TAMRA-PEG3-biotin
This product is a multifunctional probe combining a tetramethylrhodamine (TAMRA) fluorophore, a PEG3 spacer, and a biotin moiety. The TAMRA provides bright orange-red fluorescence, the PEG3 chain improves solubility and flexibility, and the biotin ensures high-affinity binding to avidin/streptavidin systems, making this reagent especially ideal for imaging, detection, and affinity-based applications.
Key Features and Benefits:
-
TAMRA Fluorophore: Strong orange-red emission for imaging and detection.
-
Biotin Group: Enables high-affinity binding to avidin and streptavidin proteins.
-
PEG3 Spacer: Enhances solubility, reduces steric hindrance, and improves biotin accessibility.
-
Dual Functionality: Combines fluorescence detection with affinity binding.
-
High Purity: Ensures reliable and reproducible experimental results.
Applications:
-
Fluorescent Imaging: Bright TAMRA signal for microscopy and flow cytometry.
-
Affinity Capture: Biotinylation enables immobilization or detection via streptavidin systems.
-
Probe Development: Serves as a dual-functional tool for biochemical assays.
-
Drug Delivery Research: Useful in designing targeted, trackable conjugates.
Storage and Handling:
-
Storage: Store at –20 °C, protected from light and moisture.
-
Handling: Use anhydrous solvents (e.g., DMSO, DMF) to preserve fluorescence and biotin activity.
This product combines bright fluorescence with biotin–streptavidin affinity in a compact PEG linker, making it an especially excellent dual-functional reagent for imaging, capture, and bioconjugation workflows.
