What IGF-II (33-40) is studied for

  • Proliferation and BrdU / EdU assays
  • Wound-healing and scratch-closure models
  • Angiogenesis (tube-formation, aortic ring) studies
  • Regenerative-medicine and stem-cell differentiation work

Mechanism of action

IGF-II (33-40) sits within the Growth Factors research class (CPC reference ILGF-005). Growth-factor peptides activate receptor tyrosine kinases (EGFR, FGFR, VEGFR, IGF-1R) and downstream RAS–MAPK and PI3K–AKT pathways that drive proliferation, migration, and survival. Investigators typically incorporate IGF-II (33-40) as a reference standard, tool ligand, or substrate in the assay contexts listed above. Phospho-ERK and phospho-AKT Western blots or AlphaLISA assays are the standard readouts.

Frequently asked questions

What is IGF-II (33-40)?

IGF-II (33-40) (CPC catalog code ILGF-005) is a synthetic growth-factor / mitogen peptide in the growth factors category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is IGF-II (33-40) studied for?

Published and internal research programs use IGF-II (33-40) as a reference standard in growth factors workflows — for example, proliferation and brdu / edu assays and wound-healing and scratch-closure models. Human clinical evidence is not established.

Is IGF-II (33-40) FDA-approved for human use?

No. IGF-II (33-40) is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.

How is IGF-II (33-40) typically used in the lab?

In a growth factors workflow, IGF-II (33-40) is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Phospho-ERK and phospho-AKT Western blots or AlphaLISA assays are the standard readouts.

How should IGF-II (33-40) be stored?

Store lyophilized at −20 °C. Reconstituted stocks stable at 4 °C for up to 2 weeks. Follow your institution's standard operating procedures for handling synthetic peptides.

Where does the IGF-II (33-40) product page point to?

This kindr reference page mirrors CPC Scientific's catalog metadata for ILGF-005. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.

What quality specifications apply to IGF-II (33-40)?

Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
