Fluorescent antibody wavelength
Webfluorescent, and luminescent. All ELISAs, regardless of the detection system employed, require the immobilization of an antigen or antibody to a surface (Corning Application Note, CLS-DD-AN-454). They also require the use of an appropriate enzyme label and a matching substrate that is suitable for the detection system being used. Associated with WebTypically the wavelength of light needed to excite the fluorophore is larger and of greater intensity than the wavelength of emitted light. The separation of the excitation wavelength maximum and the emission wavelength maximum is referred to as Stokes shift and affects both the brightness and detection of the fluorophore.

WebInvitrogen Alexa Fluor 594 dye is a bright, red-fluorescent dye that can be excited using the 561 nm or 594 nm laser lines. For stable signal generation in imaging and flow cytometry, Alexa Fluor 594 dye is pH-insensitive over a wide molar range. WebIn molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid.
WebInvitrogen Alexa Fluor 647 dye is a bright, far-red–fluorescent dye with excitation ideally suited for the 594 nm or 633 nm laser lines. For stable signal generation in imaging and flow cytometry, Alexa Fluor 647 dye is pH-insensitive over a wide molar range.

WebUseful to visualize multiple antigens simultaneously with multiple fluorophores excited at different wavelengths (multiplexing). Better, higher-resolution image quality. The signal can be amplified by using HRP antibody labels with tyramide-dyes to deposit fluorescent dyes at the site of antibody staining. More amenable to signal quantification. WebThe long wavelength emission allows for detection in complex samples with auto-fluorescent background signals. We offer Alexa Fluor 680 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and …
