Product Overview
This rabbit polyclonal antibody targets insulin-like growth factor 2 (gene igf2a) in zebrafish samples and is validated for Western blot and IHC.
In zebrafish, igf2a is one of two paralogs of insulin-like growth factor 2 that arose from the teleost genome duplication. Like mammalian IGF-2, it is a growth-promoting peptide hormone, and it is studied in zebrafish embryonic growth and development.
| Target | Insulin-like growth factor 2 (gene igf2a; UniProt Q9PUD0, zebrafish) |
|---|---|
| Host / Clonality / Isotype | Rabbit / Polyclonal / Rabbit IgG |
| Reactivity | Zebrafish |
| Form | Lyophilized |
| Formulation | Per vial: 4 mg trehalose; 0.9 mg NaCl; 0.2 mg Na2HPO4 |
| Storage | As supplied: −20 °C for up to 12 months from receipt. After reconstitution: 4 °C for up to 1 month, or aliquot and keep at −20 °C for up to 6 months. Avoid repeated freeze–thaw cycles. |
Validated Applications
| Western blot | 0.25–0.5 µg/mL (Zebrafish) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Zebrafish) |
Samples with a confirmed band (WB): zebrafish embryo tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Samples with confirmed staining (IHC): zebrafish eye tissue, zebrafish brain tissue, zebrafish liver tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Recombinant zebrafish IGF2A fragment (Gly41–Lys197), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with zebrafish. UniProt describes insulin-like growth factor 2 as a secreted protein. 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).
