Rabbit Anti-Alexa Fluor 350 Antibody, iFluor® 350-Labeled
Product key features
Rabbit Anti-Alexa Fluor 350 Antibody, iFluor® 350-Labeled is a polyclonal antibody labeled with iFluor® 350 for direct detection of Alexa Fluor® 350 conjugates.
- Direct Detection: iFluor® 350 allows single-step blue fluorescence detection of Alexa Fluor® 350 targets.
- Matched Fluorophores: Designed for use with Alexa Fluor® 350 and other blue fluorophores like iFluor® 350 and AMCA.
- Polyclonal Format: Rabbit-derived for broad recognition of Alexa Fluor® 350-labeled molecules.
- Multipurpose Use: Ideal for signal amplification, conjugation verification, and multiplexed fluorescence detection.
Product description
Rabbit Anti-Alexa Fluor 350 Antibody, iFluor® 350-Labeled is a polyclonal antibody that specifically binds to Alexa Fluor® 350-conjugated molecules and is directly labeled with iFluor® 350, a UV-excitable blue fluorophore with excitation around 350 nm and emission near 442 nm. This direct labeling enables one-step fluorescence detection, reducing assay complexity and minimizing background signal.
The antibody may cross-react with structurally similar dyes such as iFluor® 350, AMCA, and Cascade Blue®. It is ideal for signal amplification in low-abundance target detection, verifying dye conjugation efficiency, and performing multiplex fluorescence assays in microscopy, ELISA, and flow cytometry.
