Protein G DyLight™ 800 Conjugated

Protein G is a surface protein of two groups of Streptococcal bacteria that has the ability to bind immunoglobulins. Similar to Protein A, but with slightly different specificity, Protein G is an important agent in the purification of proteins due to its ability to bind the Fc region. While native Protein G binds to albumin, recombinant Protein G is designed to contain only immunoglobulin binding domains to ensure the maximum specific IgG binding capacity. Protein G is often immobilized on solid surface such as Sepharose™, latex or magnetic particles for IgG purification from ascites, serum or hybridoma culture media. Protein G is also coupled with reporter molecules such as a fluorescein, peroxidase, biotin, DyLight™ and other detection reagents. Protein G DyLight™800 has been tested by dot blot and is designed for immunofluorescence microscopy, fluorescence based plate assays (FLISA) and fluorescent western blotting. This product is also suitable for multiplex analysis, including multicolor imaging, utilizing various commercial platforms. The emission spectra for this DyLight™ conjugate match the principle output wavelengths of most common fluorescence instrumentation.
