    eIF3β Antibody (A-12) is a mouse monoclonal IgG2a antibody that detects eIF3β in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). eIF3β is a critical component of the eukaryotic initiation factor 3 complex, which plays a pivotal role in protein synthesis regulation by facilitating 40S ribosomal subunit assembly. eIF3β is located in the cytoplasm, where eIF3β interacts with other initiation factors and mRNA to form the pre-initiation complex necessary for translation. Proper localization of eIF3β is essential for efficient protein synthesis, ensuring correct ribosomal subunit assembly and effective translation machinery engagement. Notably, dysregulation of eIF3β expression has been linked to various cancers, highlighting eIF3β′s importance in cellular growth and proliferation. anti-eIF3β antibody (A-12) provides a valuable tool for researchers studying translation initiation mechanisms and cancer biology implications, allowing detailed analysis of eIF3β′s role in both normal and pathological states.
