GDF-8 listed as a research-use product. Chemical identity, specifications, and analytical data should be verified against the supplier's current COA and product documentation.
Soluble in aqueous acidic solution; recombinant protein is commonly reconstituted in 20 mM HCl at 0.1 mg/mL
Storage
Lyophilized protein: store at -20°C; for long-term storage, -20°C to -80°C; after reconstitution, store at 4°C for short-term use or aliquot and store frozen; avoid repeated freeze-thaw cycles, For details, please consult customer service

Frequently Asked Questions
Yes, every batch comes with a batch-specific Certificate of Analysis including HPLC purity results, mass spectrometry confirmation, and complete test documentation. COAs are available for download on each product page and in our Quality section.
All products are verified at ≥99% purity through HPLC analysis, with most batches achieving ≥99%. The exact purity for each batch is documented in the COA and listed on the product detail page.
Lyophilized (freeze-dried) peptides should be stored at -20°C or lower in a sealed container to prevent moisture absorption. Once reconstituted, store aliquots at -20°C and avoid repeated freeze-thaw cycles. Most peptides remain stable for 1-2 years when properly stored. Always refer to the specific storage instructions on the COA for each batch.
Use sterile bacteriostatic water or appropriate buffer (e.g., PBS, acetic acid solution depending on peptide solubility). Add solvent slowly along the vial wall to avoid foaming. Gently swirl—do not vortex—to dissolve. For hydrophobic peptides, a small amount of DMSO may be required first. Calculate concentration based on molecular weight provided in the COA. Always filter through a 0.22 μm membrane if sterility is required.
Dosage depends entirely on your experimental protocol, target receptor affinity, and model system. We provide molecular weight, sequence, and purity data so you can calculate molar concentrations accurately. Consult peer-reviewed literature for your specific research application. Our technical team can assist with stoichiometric calculations but cannot recommend biological dosing.
Solubility varies by sequence. Hydrophilic peptides (rich in charged residues like Arg, Lys, Asp, Glu) typically dissolve readily in aqueous buffers. Hydrophobic peptides may require organic co-solvents (DMSO, acetonitrile) or acidic/basic conditions. The COA includes solubility notes for each batch. If uncertain, start with a small test aliquot before full reconstitution.
Reconstituted peptides are generally stable for 1-4 weeks at 4°C or 3-6 months at -20°C, depending on sequence and buffer composition. Peptides containing Cys, Met, or Gln residues are more prone to oxidation/deamidation and should be used promptly. Aliquot immediately after reconstitution to avoid degradation from repeated thawing.
All shipments use temperature-controlled cold chain logistics to maintain product integrity during transit. Lyophilized peptides are shipped at ambient temperature in sealed, desiccated vials—this is standard practice as freeze-dried peptides are stable at room temperature for short periods. Reconstituted products (if applicable) ship on dry ice. We offer express delivery options to over 50 countries worldwide.
Yes, we offer custom peptide synthesis services up to 50 amino acids. Contact us via WhatsApp or email with your sequence, desired purity (crude/≥95%/≥99%), modifications (acetylation, amidation, biotinylation, etc.), quantity, and timeline. Our technical team will provide a quote, feasibility assessment, and estimated lead time (typically 2-4 weeks).
