RecQL1 Antibody (A-9) is a mouse monoclonal IgG2a kappa light chain antibody that detects RecQL1 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Anti-RecQL1 antibody (A-9) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. RecQL1 plays a crucial role in maintaining genomic stability by unwinding DNA during replication and repair processes, which is vital for preventing mutations that can lead to cancer and other genetic disorders. As a member of the RecQ helicase family, which includes other important proteins such as WRN and BLM, RecQL1 is involved in critical cellular functions, and dysregulation can contribute to genomic instability. Expression levels of RecQL1 are particularly important in cells that are actively proliferating or undergoing transformation, as these levels help ensure genome integrity under stress conditions. The gene encoding human RecQL1 is located on chromosome 12p12.1, and understanding function and interactions with other proteins can provide insights into cellular processes and potential implications in disease.
