IκB-α Antibody (H-4) is a mouse monoclonal IgG1 kappa light chain antibody that detects IκB-α in mouse, rat, and human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry (IHC), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). IκB-α plays a crucial role in the regulation of the NF-κB signaling pathway, which is essential for controlling immune responses, inflammation, and cell survival. By sequestering NF-κB dimers in the cytoplasm, IκB-α prevents their translocation to the nucleus, thereby inhibiting the expression of target genes involved in these processes. IκB-α (H-4) antibody maintains cellular homeostasis and prevents excessive inflammatory responses, which can lead to various diseases, including cancer and autoimmune disorders. IκB-α (H-4) monoclonal antibody is available in both non-conjugated and multiple conjugated forms, including agarose, horseradish peroxidase, phycoerythrin, fluorescein isothiocyanate, and various Alexa Fluor® conjugates, making IκB-α (H-4) antibody a versatile tool for researchers studying the NF-κB pathway and its implications in health and disease.

Can this antibody also detect the phospho form of IκBα?

Asked by: bob272
Thank you for your question. IκB-α (H-4) is recommended for detection of IκB-α of mouse, rat and human origin by WB, IP, IF, IHC and FCM. It cannot detect the phospho form of IκB-α.

what is "h-4" mean in this antibody?

Asked by: Hayoung
Thank you for your question. The “(H-4)” is the clone designation for this antibody. It is simply a unique identifier for the antibody.
