Product Overview
Clone 17F48 is a rabbit monoclonal antibody that recognizes flap endonuclease 1 (gene FEN1) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 42.6 kDa, and the supplier reports an observed band at about 42 kDa.
Flap endonuclease 1 (FEN1) is a structure-specific nuclease that removes the 5′ flaps formed during Okazaki fragment processing, allowing the lagging DNA strand to be joined. It also takes part in long-patch base excision repair and helps maintain genome stability, so it is studied in DNA replication, repair and cancer biology.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
