Product Overview
Clone 24F44 is a rabbit monoclonal antibody that recognizes fos-related antigen 2 (gene FOSL2) in human, mouse and rat samples and is validated for Western blot, immunoprecipitation and flow cytometry. The predicted molecular weight is 35.2 kDa, and the supplier reports an observed band at about 45 kDa.
Fra-2 (FOSL2) is a FOS family transcription factor that forms AP-1 complexes with JUN proteins. It regulates genes involved in bone cell differentiation, including the survival and size of osteoclasts, and it is also studied in fibrosis, immune regulation and cancer.

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).
