Human IgG4 kappa, Isotype Control（Cat No.:I044218）is a recombinant monoclonal antibody that does not bind any known antigen, making it an ideal negative control for immunoassays such as flow cytometry, ELISA, and immunohistochemistry. It matches the IgG4 kappa isotype of test antibodies, allowing for accurate assessment of background staining and nonspecific binding. Expressed in human cells, it maintains native structure and glycosylation, ensuring compatibility with human systems. This isotype control is essential for verifying assay specificity and improving confidence in immune profiling, therapeutic antibody validation, and biomarker research.
