Application Guide: In-Cell Western™ Assay Development Handbook

Develop reliable In-Cell Western assays with practical guidance for every stage of optimization. Learn how this quantitative, plate-based immunofluorescence method supports higher-throughput protein detection in a cellular context, then work through key decisions involving experimental design, normalization, cell seeding, antibody validation, fixation, permeabilization, blocking, and antibody concentration. Guidance on controls, replicates, linearity, and Z’-factor analysis helps strengthen reproducibility and reveal whether an assay is ready for routine use. An example project demonstrates how these principles can be applied to quantify changes in ERK1/2 phosphorylation, while supplementary protocols, plate layouts, calculation references, troubleshooting tips, and frequently asked questions provide support at the bench.
