Used for isolating and enriching specific proteins from complex biological samples such as cell lysates or tissue extracts. The magnetic bead format allows for rapid and efficient capture of target proteins using antibodies bound to Protein A and G, which have high affinity for immunoglobulins. This kit is ideal for downstream applications including Western blotting, mass spectrometry, and protein-protein interaction studies. Its magnetic separation feature simplifies workflow by eliminating centrifugation steps, reduces sample loss, and improves reproducibility. Commonly used in research settings to study signaling pathways, post-translational modifications, and biomarker validation.
