53BP1 Antibody (6B3E10) is a mouse monoclonal IgG1 antibody that detects 53BP1 in human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). 53BP1 plays a crucial role in the cellular response to DNA damage, particularly in double-strand breaks, by facilitating repair processes and maintaining genomic stability. Anti-53BP1 antibody (6B3E10) recognizes nuclear localization, where 53BP1 is essential for activating DNA damage response pathways and managing DNA lesions. 53BP1 dysregulation can lead to genomic instability and contribute to tumorigenesis. Furthermore, 53BP1 interacts with various proteins involved in DNA repair, including p53, highlighting a significant role in tumor suppression mechanisms. Anti-53BP1 antibody (6B3E10) serves as a valuable tool for studying DNA damage response pathways and their implications in cancer biology.

Rated 5 out of 5 by from Cost effective!Works just as good (or better) than a more expensive antibody that I was using for the same purpose. This is going to save our lab a lot of money.
