Product Overview
This rabbit polyclonal antibody detects eukaryotic translation initiation factor 4 gamma 2 (gene EIF4G2) in human, mouse, rat and monkey samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 102.4 kDa, and the supplier reports an observed band at about 97 kDa.
EIF4G2 (also called DAP5 or p97) is an eIF4G-related protein that lacks the eIF4E-binding region. It supports cap-independent translation of certain mRNAs, for example during mitosis, apoptosis and stress, and it is studied in alternative translation initiation.

Immunogen
Recombinant human P97/DAP5/EIF4G2 fragment (Arg23–Gln889), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse, rat and monkey. Tissue expression noted by UniProt (human): Ubiquitously expressed in all adult tissues examined, with high levels in skeletal muscle and heart. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
