Key Analytical Items for Peptide Synthesis:
Standard peptide synthesis reports include MASS and HPLC reports to verify the correctness of the peptide sequence. If your research requires control over additional parameters, such as the percentage of correct and complete peptides among all peptides, please feel free to inquire about Yao-Hong's other analytical services.
-
Use the results of these tests to perform a mass balance calculation (% Target Peptide + % Peptidic Impurities + % Counter ion + % Water = 100%) to ensure that all peptide preparation components have been accounted for.
-
Net peptide refers to the combined fractions of the target peptide and peptidic impurities (i.e. deletion peptides). Counter ions and water are not considered part of the net peptide content. The amount of the target peptide is calculated by the multiplication of gross weight x net peptide content x HPLC purity.
Custom Peptide Synthesis Advisory Information
You are not required to make any payment before confirming your order. Prices will vary based on the desired peptide's amino acid sequence, length, purity, and modifications. Upon receiving your custom peptide details, such as the sequence, we will provide you with a quotation, delivery information, or recommendations. (Occasional promotions and special offers may be available.)
Q. Regarding Difficult-to-Synthesize Amino Acids
A. Peptides containing complex Cys, Met, or Trp residues are more challenging to achieve high purity standards, partly due to the highly oxidizable nature of these amino acid residues. Therefore, the design of peptide sequences should ideally avoid Cys, Met, or Trp residues.
Q. Regarding Peptide Solubility
A. The solubility of peptides depends on their amino acid composition and sequence arrangement. Peptides containing a high proportion of hydrophobic amino acids (e.g., Leu, Val, Ile, Met, Phe, and Trp) will have limited or no solubility in aqueous solutions. Therefore, for peptide synthesis, we recommend that the content of hydrophobic amino acids be kept below 50% to minimize issues in synthesis or purification.
Q. Regarding Secondary Structure
A. During the synthesis process, the formation of β-sheet structures can lead to a certain degree of sequence disruption. This issue can be mitigated by avoiding the selection of complex amino acids such as Val, Ile, Tyr, Phe, Trp, Leu, Gln, and Thr.
