PEG-MGF research peptide — wholesale supply

For research use only · Not for human consumption · Not for veterinary use. This product is supplied for in-vitro research, analytical method development, and laboratory reference standard use only. Not approved for human or veterinary administration. Buyer is responsible for end-use classification in the destination jurisdiction.

Overview

PEG-MGF is the pegylated form of the C-terminal 24-amino-acid peptide of the IGF-1Ec splice variant, also referenced as Mechano Growth Factor (MGF). The pegylation at the N-terminus extends the in-vitro half-life of the peptide relative to the unpegylated form, and the compound is supplied as a research-grade lyophilized powder for in-vitro cell-based assays, IGF-1 receptor and IGF-1Ec-specific pathway research, and analytical method development. SPK Pharma India supplies PEG-MGF as a documented, lot-traceable research compound for distributors, contract manufacturers, and academic laboratories.

Specifications

Research context

The MGF peptide backbone is the C-terminal 24-amino-acid peptide of the IGF-1Ec splice variant, which is expressed in skeletal muscle in response to mechanical loading and is studied in cell-based research on muscle cell proliferation, satellite cell activation, and IGF-1Ec-specific signalling. The pegylated form is supplied for research contexts where the extended in-vitro half-life of the pegylated form is the variable of interest, distinguishing it from the unpegylated MGF peptide.

In-vitro receptor-binding assays, cell proliferation studies in defined muscle cell lines, and analytical method development for LC-MS quantification are the typical research applications. SPK Pharma India does not make therapeutic, clinical, diagnostic, or dosing claims for this product. The compound is supplied strictly for in-vitro research, analytical method development, and reference-standard work.

For researchers new to the compound, the standard analytical reference points are CAS 108006-87-7, the 24-amino-acid MGF backbone, the N-terminal PEG modification, the lot-specific molecular weight (variable, depending on PEG chain length), the lyophilized powder form, and the documented purity threshold (≥99% HPLC on a peptide basis). The full amino acid sequence, the PEG chain length, and the lot-specific molecular weight are disclosed on the lot-matched COA and on the product specification sheet.

Packaging and supply

• 2 mg research vial — for method development, receptor-binding assays, and reference-standard qualification. Standard MOQ: 5 vials.
• 5 mg research vial — for ongoing research programmes with higher per-assay demand. Standard MOQ: 2 vials.
• Bulk pack — on application, for annual supply contracts and recurring orders.

Distributor pricing is available on application. Annual supply contracts with scheduled recurring dispatch are available for repeat buyers. Lead time for in-stock SKUs is typically 5 business days from purchase order confirmation; lead time for scheduled production is typically 4 to 6 weeks.

Quality and documentation

Every lot of PEG-MGF ships with a lot-matched Certificate of Analysis documenting identity (mass spectrometry and amino acid analysis), purity (HPLC on a peptide basis; PEG component reported separately), PEG chain length, lot-specific molecular weight, appearance, lot number, and synthesis batch reference. A representative sample of every lot is independently verified by a third-party analytical laboratory before release. MSDS is supplied with every shipment. The COA template, the lot-traceability workflow, and the third-party verification scope are documented on the Quality page.

Storage and handling

• Store at -20°C in the original sealed container.
• Protect from light and moisture.
• Allow the sealed container to reach room temperature before opening, to avoid condensation.
• Reconstitute in sterile, low-endotoxin research-grade water or in a mild buffer at the working concentration required by the assay.
• Do not refreeze once reconstituted; aliquot and store at working concentration.
• For pegylated peptides, avoid vigorous vortexing; allow gentle dissolution to minimise aggregation.

Shipping

PEG-MGF is shipped lyophilized in sealed vials within temperature-validated packaging. International lanes are routed through dedicated life-science logistics partners with cold-chain handling. Standard dispatch is within 5 business days of purchase order confirmation. SPK Pharma India ships to the United States, the European Union, the United Kingdom, Canada, MENA, APAC, and LATAM. Full export documentation, including commercial invoice, packing list, certificate of origin, COA, and MSDS, is included with every shipment. Destination-specific documentation is supported on request.
