Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.Human IGF-BP3

- BACKGROUND
| Description | IGF-BP3 is a 30 kDa cysteine-rich secreted protein. It is the major IGF binding protein present in the plasma of human and animals and it is also found in α-granules of platelets. In addition to its ability to modulate the activity of IGF-I and IGF-II, IGF-BP3 exerts inhibitory effects on follicle stimulating hormone (FSH) activity. Decreased plasma levels of IGF-BP3 often results in dwarfism, whereas elevated levels of IGF-BP3 may lead to acromegaly. The expression of IGF-BP3 in fibroblasts is stimulated by mitogenic growth factors such as Bombesin, Vasopressin, PDGF, and EGF. Recombinant human IGF-BP3 is a 28.8 kDa protein consisting of 264 amino acid residues. |
|---|---|
| BiologicalActivity | The ED50 was determined by its ability to inhibit IGF-II induced proliferation of MCF-7. The expected ED50 for this effect is ≤ 0.2 µg/ml in presence of 15 ng/ml of human IGF-II. |
| Authenticity | Verified by N-terminal and Mass Spectrometry analyses (when applicable). |
| Endotoxin | Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg). |
| Protein Content | Verified by UV Spectroscopy and/or SDS-PAGE gel. |
| Storage | -20°C |
| Precautions | Human IGF-BP3 is for research use only and not for use in diagnostic or therapeutic procedures. |
