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-Mouse IgG StarBright Blue 520 has been cross-adsorbed against bovine, goat, human, rabbit and rat.

Target Species
Product Form
Purified IgG conjugated to StarBright Blue 520 - lyophilized
Resuspend contents of the tube in the indicated volume of distilled or deionized water and leave on ice for at least 30 min prior to use. Brief centrufugation (pulse spin for 2-3 sec at max speed in a tabletop microcentrifuge) may be used to collect the contents at the bottom of the tube. Do not centrifuge more than 10 sec.
Antiserum Preparation
Antiserum to Mouse IgG was raised by repeated immunisation of Goats with highly purified antigen.
