Peptide delivery timelines can be affected by factors related to synthesis, quality control, logistics, and order requirements.

Store Lyophilized Peptides at -20°C or -80°C, most lyophilized peptides can remain stable for months to years, depending on the peptide sequence and storage environment.

Delivery times strongly depend on the scale, purity, order volume and peptide sequence.

Without specific requests, peptides in lyophilized powder format will be sent out at room temperature.

Peptides are commonly supplied as freeze-dried powder after purification and lyophilization. However, the final visual appearance of the powder can be affected by several factors

We use advanced peptide purification methods to ensure high purity, sequence accuracy, and reliable performance for research, preclinical, and pharmaceutical applications. The most widely used method is Reversed-Phase High-Performance Liquid Chromatography, commonly known as RP-HPLC.

Peptide purity tells you how much of the target peptide is present compared with peptide impurities.
Peptide content tells you how much actual peptide is present in the total sample weight.

We can routinely synthesize peptides exceeding ‌100 amino acids‌ in length, and our longest successfully synthesized linear peptide via advanced solid-phase synthesis technology reaches 156 amino acids‌.

The best peptide salt form depends on your application, biological compatibility, stability, solubility, and downstream formulation needs. For most biological and preclinical work, acetate salt is usually the safest default choice. For routine analytical or non-cell-based work, TFA salt is often acceptable.

Net peptide content refers to the actual amount of pure peptide present in a peptide sample, expressed as a percentage of the total weight. It does not include water, salts, counterions, residual solvents, or other non-peptide impurities that may be present after synthesis, purification, or lyophilization.
