Uses for immunofluorescence (IF)—where an antibody conjugated to a molecule that fluoresces when excited by lasers— include protein localization, confirmation of post-translational modification or activation, and proximity to/complexing with other proteins.
Proteins are complex biological molecules essential for cellular structure and functions. The majority of proteins commonly interact with various molecules, including other proteins, in order to exert their functions.
Our aim was to investigate the dimerization and activation pattern of two receptors, EGFR (ErbB1) and HER2 (ErbB2), in the EGFR-family using breast cancer cell lines and selected colon tissues as model systems.
Traditional flow cytometry has been limited in the ability to detect protein-protein interactions and low abundant proteins events — until now. We have combined Duolink® Proximity Ligation Assay (PLA) with flow cytometry in a convenient kit, making the analysis of
Learn about homobifunctional sulfoxide-containing MS-cleavable cross-linkers that enables the capture of protein-protein interactions (PPIs) in native cellular environments, and the identification of cross-linked peptides permits the determination of both identity and connectivity of PPIs.
