Protein G Separopore® 4B-CL

Applications:

• Protein G binds specifically to F_c regions of many mammalian immunoglobulins.
• Protein G conjugates are commonly used as affinity adsorbents to purify immunoglobulins (antibodies) and immunoglobulin subtypes from serum, hybridoma ascites fluids, tissue culture supernatants and other biological fluids.
• These reagents are also commonly used to capture immune complexes generated in immunoprecipitation experiments.
• Affinity matrix with immobilized protein G (from Streptococcus sp.) by CNBr activation coupling method.
• Protein G-Separopore^® 4B-CL is used for purification and/or fractionation of IgG subclasses which bind poorly to protein-A such as bovine, goat, rat and sheep IgG.

Note: Separopore® is a cost-effective equivalent to Sepharose® in all of its physical properties and binding characteristics.
