IgG antibody
StarBright Blue 520 Fluorescent Secondary Antibodies can be used for multiplex fluorescent western blotting with Bio-Rad's ultra-sensitive near IR StarBright Blue 700 Antibodies and the hFAB Rhodamine Anti-Housekeeping Antibodies as described in the table above.
* Stain-free gels can be used for total protein normalization in place of or in addition to housekeeping proteins (HKP)
Composite blot image with four distinct proteins visualized using StarBright Blue 520 and StarBright Blue 700 Secondary Antibodies, in combination with DyLight 800, and a rhodamine labeled recombinant human hFAB antibody for the detection of popular housekeeping proteins on the ChemiDoc MP Imaging System.
The StarBright Blue 520 Fluorophore is an ultra-sensitive polymer-based fluorophore with an excitation maximum at 488 nm and emission maximum at 520 nm. The StarBright Fluorophore is made up of multiple light-absorbing and -emitting monomers which provide an exceptionally bright signal compared to most traditional fluorophores.
StarBright Blue 520 Conjugated Goat Anti-Mouse and Goat Anti-Rabbit Fluorescent Secondary Antibodies are ideal for fluorescent western blotting — either for the detection of a single-target protein or for multiplex detection of several proteins on one blot, without stripping and reprobing. StarBright Blue 520 Fluorescent Secondary Antibodies can be used with far-red emission StarBright Blue 700 Antibodies as well as traditional fluorescent detection reagents like Alexa Fluor and DyLight Conjugated Antibodies. In addition, StarBright Antibodies can be used with Bio-Rad's stain-free technology and/or with hFAB™ Rhodamine Anti-Housekeeping Primary Antibodies for protein normalization. These antibodies are optimized for use with the ChemiDoc™ MP Imaging System, permitting detection of up to three proteins in a single blot.
Features and Benefits
Easy multiplexing — can be used with traditional fluorescent antibodies or with Bio-Rad's StarBright Blue 700 Fluorescent Secondary Antibodies to detect multiple proteins on the same blot
High sensitivity — StarBright Blue 520 Fluorescent Secondary Antibodies (Exmax/Emmax = 488 nm/520 nm) have 2–4 fold higher sensitivity compared to traditional green emitters like Alexa Fluor 488 or DyLight 488 Antibodies
Short exposure time — the exceptional brightness of the StarBright Fluorophore leads to shorter exposure times compared to traditional fluorescent dyes: seconds vs. minutes
Low nonspecific binding — conjugated to highly cross-adsorbed antibodies
Goat Anti-Rabbit IgG StarBright Blue 520 has been cross-adsorbed against bovine, goat, human, mouse and rat.
