Description

Protein G Cell Suspension is a high-quality, ready-to-use biological reagent designed for the efficient purification of monoclonal antibodies, particularly IgG subclasses from various species. This product matters because it offers superior binding capacity and specificity compared to Protein A for many antibody types, streamlining downstream bioprocessing and research workflows. It is an essential tool for biotechnology and pharmaceutical companies engaged in antibody discovery, production, and quality control, as well as for academic research institutions focusing on immunology and protein science.

Application

• Affinity chromatography for the purification of monoclonal and polyclonal antibodies.
• Immunoprecipitation (IP) and co-immunoprecipitation (Co-IP) assays to isolate protein complexes.
• Immobilization on solid supports for the development of diagnostic assays and biosensors.
• Generation of immunoaffinity columns for large-scale Good Manufacturing Practice (GMP) bioprocessing.
• Capture and detection reagent in enzyme-linked immunosorbent assays (ELISA).
• Research and development in antibody engineering and characterization.
• Sample preparation for mass spectrometry and other analytical techniques.
