Recombinant human IGF-2 protein (Qk118)

Product: Qk118 Category:

Price range: £175.00 through £880.00

Insulin-like Growth Factor 2 (IGF-2) is a growth factor that promotes cell proliferation, differentiation, and survival, particularly during fetal development. IGF-2 also regulates tissue growth and muscle regeneration. Recombinant IGF-2 stimulates proliferation and differentiation in various stem cell cultures.

Qkine human IGF-2 is a highly pure 7.5 kDa monomer, animal origin-free (AOF) and carrier-protein-free (CF). Qkine has optimized the IGF-2 manufacturing process to produce a highly bioactive protein with excellent lot-to-lot consistency for enhanced experimental reproducibility.

This protein is also available as GMP compliant Cell Therapy Grade, to enquire email ryan.weber@matriqx.com.

Recombinant IGF-2 activity was determined using an SRE reporter assay on transfected MCF-7 cells. Cells were treated in triplicate with a serial dilution of IGF-2 for 4 hours. Firefly activity was measured and normalized to the control Renilla luciferase activity. Data from Qk118 lot 204687. EC50 = 58 ng/ml (7.8 nM)

Recombinant IGF-2 migrates at approximately 7.5 kDa in reduced (R) and non-reduced (NR) conditions. No contaminating protein bands are present. The purified recombinant protein (3 µg) was resolved using 18% w/v SDS-PAGE in reduced (+β-mercaptoethanol, R) and non-reduced (NR) conditions and stained with Coomassie Brilliant Blue R250. Data from Qk118 lot #204687.

Qk118 IGF 2 Peprotech comparison

Qkine IGF-2 is as biologically active as the comparable alternative supplier protein. IGF-2 activity was determined using the serum response element (SRE) firefly luciferase reporter assay in transfected MCF-7 cells. Cells were treated in triplicate with a serial dilution of IGF-2 (Qk118, green) or alternative supplier IGF-2 (supplier B, black). Firefly luciferase activity was measured and normalized to the control Renilla luciferase activity. Data from Qk118 lot #204687.

Protein background

IGF-2, or Insulin-like Growth Factor 2, is a protein hormone that plays a crucial role in growth and development, particularly during fetal development. It is part of the insulin-like growth factor family, which includes IGF-1 and insulin. IGF-2 is a single-chain polypeptide consisting of 67 amino acids, with a molecular weight of 7.5 kDa. The protein’s three-dimensional structure is characterized by three alpha-helices stabilized by three disulfide bonds [1]. These disulfide bonds are formed between six conserved cysteine residues, which are critical for maintaining the protein’s tertiary structure and biological activity. The overall fold of IGF-2 is similar to that of insulin, reflecting their evolutionary relationship [2].

IGF-2 has numerous applications across various fields. In prenatal development, it is crucial for fetal growth and development, influencing organ size and body composition. It’s used as a marker in prenatal diagnostics to assess fetal growth and potential developmental issues [3]. In cancer research, IGF-2 has been implicated in various cancers, including colorectal, breast, and prostate cancer. It’s being studied as a potential biomarker for early cancer detection and as a target for cancer therapies. Given its role in glucose metabolism, IGF-2 is also being investigated in the context of metabolic disorders such as diabetes and obesity, with researchers exploring its potential in developing new treatments [4].

IGF-2 has tissue engineering and regenerative medicine applications, particularly in wound healing and tissue repair. IGF-2 has neuroprotective effects, suggesting potential applications in treating neurodegenerative disorders like Alzheimer’s disease. IGF-2 gene polymorphisms are used as genetic markers for selective breeding to improve meat quality and production efficiency [5]. Additionally, as a growth factor, IGF-2 is monitored in sports medicine to detect potential abuse for performance enhancement. The ongoing research into IGF-2’s structure and functions continues to open new avenues for applications in medicine, biotechnology, and agriculture, underlining its significance across multiple disciplines [6].
