Human ERBB2IP ELISA Kit (HUFI04418)

ERBB2IP (Erbb2 Interacting Protein, also known as Erbin) is a PDZ-domain scaffolding protein that binds the intracellular tail of the ERBB2/HER2 receptor tyrosine kinase and participates in basolateral epithelial polarity, junctional complex assembly, and downstream Ras signaling. Quantifying ERBB2IP expression in human specimens therefore supports research into HER2-associated tumor biology, receptor trafficking, and epithelial barrier function in cancer and tissue-model studies.

This quantitative immunoassay kit from Assay Genie is configured on a standard microplate and provides the buffers, standards, and detection reagents needed to generate a calibration curve and interpolate ERBB2IP concentrations from prepared human samples. The assay is intended for research use only and fits laboratory workflows measuring endogenous Erbin levels in cell lysates and other human-derived specimens prepared by the user.

Each kit ships with a coated microplate and reagents sufficient for the stated plate configuration, allowing researchers to run multiple samples alongside a standard curve in a single workflow. Colorimetric readout is captured on a standard plate reader, and results are interpreted against the provided recombinant ERBB2IP reference standard. Investigators studying HER2 pathway crosstalk, colorectal and breast cancer cell models, or PDZ-domain-mediated signaling will find this microplate kit a practical addition to their experimental pipeline.
