Custom peptides from AAPPTec are provided quickly and are competitively priced because AAPPTec’s chemists have up to 25 years experience in preparing high quality peptides. Using their experience our chemists prepare high purity peptides that minimize overall costs because less materials are used and less purification is required.
AAPPTec can provide custom peptides containing up to 85 amino acids. We utilize the latest proven methods, including sonication, reaction heating, pseudoprolines and Dmb-protected amino acids to produce high purity, high yield peptides, even of difficult sequences or modified sequences.
AAPPTec will provide custom peptides with the purity specifications you require. The purity levels listed below are the standard purity levels you may specify for your custom peptides.
|80% or greater
||Forming antibodies; tissue culture; ligand for affinity purification; non-quantitative antibody blocking experiments
|90% or greater
||In vivo studies; bioassays; markers for electrophoresis; monoclonal antibodies
|95% or greater
||ELISA;RIA: enzyme substrate
|98% and above
||NMR; chromatography standards
Custom peptides can be provides as TFA salts as desalted peptides.
AAPPTec will prepare custom peptides containing unusual amino acids, isotopically labeled amino acids, cyclizations, side chain modifications, N-terminal and/or C-terminal modifications.

2. What type of chemistry do you use?
AAPPTec generally utilizes Fmoc chemistry for most peptide production.
3. How do you generally purify your peptides?
Our peptides are generally purified by preparative reversed phase HPLC, using trifluoroacetic acid (TFA) modified buffers at pH 2. Buffer A is 0.1 % TFA deionized water and buffer B is 0.1 % TFA in acetonitrile (ACN) at pH 2. Peptides are dissolved in either straight buffer A, or some
amount of buffer B then diluted with buffer A.
Sometimes it is necessary to use an organic polar solvent like (formic acid or acetic acid) in DMSO or DMF to aid in the dissolving of hydrophobic peptides but this is done on a case-by-case basis depending on the sequence analysis. The separation is monitored by UV at 214 nm and fractions are collected and analyzed by mass spectrometry for product identity and by reversed phase analytical HPLC for purity.
The fractions are then lyophilized to remove the solvents. The fractions that meet the specifications of the order are then combined into one vial. Next, we run a final mass spectrum and analytical HPLC on the combined material.
