Chk2 Antibody (A-11) is a mouse monoclonal IgG1 kappa light chain antibody that detects Chk2 of mouse, rat, and human origin through western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Chk2 monoclonal antibody (A-11) is offered in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase, phycoerythrin, fluorescein isothiocyanate, and multiple Alexa Fluor® conjugates. Chk2 plays a critical role in the cellular response to DNA damage, functioning as a key regulator in the G2 DNA damage checkpoint. By phosphorylating Cdc25C in response to DNA damage, Chk2 inhibits the activity of this phosphatase, effectively blocking the progression of mitosis until the damage is repaired. This regulatory mechanism is vital for maintaining genomic stability, as preventing cells with damaged DNA from entering mitosis reduces the risk of propagating mutations. The interaction of Chk2 with other proteins, such as Cdc25C, highlights the importance in the intricate network of cell cycle regulation and DNA damage response, making Chk2 (A-11) antibody an essential tool for researchers studying these critical cellular processes.

I am using the LiCor/Odyssey system. Which secondary antibody do you recommend using with Chk2 (A-11): sc-17747 monoclonal antibody?

Asked by: jenniferc
We recommend using one of our our exclusive Mouse IgG Binding Proteins (m-IgGκ) conjugated to CFL 680 or CFL 790. They are suitable for use with Near-Infrared (NIR) detection systems, such as LI-COR/Odyssey and other comparable systems. A complete list of available binding proteins is available on our website here: https://www.scbt.com/scbt/browse/support-products-mouse-igg-binding-proteins/_/N-ecrety
