LifeTein®, the custom peptide synthesis service company, has developed a proprietary PeptideSynTM technology. This technology provides a platform for continuous peptide synthesis using Fmoc and Boc chemistry, microwave technology, and a proprietary solid support resin. This is one of the many reasons why LifeTein® can offer low competitive pricing.
LifeTein routinely uses our proprietary microwave technologies to produce peptides >100 amino acids. The longest peptide we have made to date is 169 amino acids. We promise to provide the HPLC purified peptide with the correct molecular weight analyzed by Electrospray ionization (ESI) Mass Spectrometry.
LifeTein provides peptides with special modifications including Peptide Oligo Conjugate, Stapled Peptide, Stable Isotope Labeled Peptides, Peptide Nucleic Acids, Fluorescent Peptide: Cy3/Cy5/Cy7, Phosphorylated Peptide, Glycosylation, Peptide pool service, Biotinylated Peptides, Cell-Permeable Peptide, Cyclic Peptide, Long Peptide Synthesis: 169AA, MAP Peptide Synthesis, and D Amino Acid Peptide.

NUCLEIC ACID VECTORS AND USES THEREOF: LifeTein synthesized a peptide of 133 amino acids. The peptide sequence includes at least one cell-permeable peptide (CPP) domain, one secretion signal sequence, one DNA binding domain, and other SHT protein.
Phosphorylation: Posttranslational modification on Tyr, Ser and Thr residues, signal transduction, gene expression and protein-protein interaction
Biotinylation: Strong affinity for streptavidin and avidin to be used in histocytochemistry, immunoassays, and fluorescence based flow cytometry
Cyclization: Peptides can be cyclized by disulfide bond, head-to-tail, amide or thioester cyclization to stabilize the peptide conformation, increase bioactivity, and enzyme stability
Long Peptide Synthesis: An alternative approach to exogenous protein expression
Cell Permeable Peptides: Deliver biologically active cargo to the cell interior; Enter the plasma membrane of a cell independent of a membrane receptor
Linker, Spacer, PEGylations: Reduce steric hindrance at the binding sites of the peptide and improve proteolytic stability and solubility of peptides
FITC: FITC, FAM, TAMRA, Rhodamine, Dansyl, 4-Dinitrophenyl (Dnp), 7-methoxycoumarin acetic acid (Mca) Cy3, Cy5, Cy7 for Fluorescence based assays, flow cytometry, protein-protein interaction, and localization studies
Short Peptide Synthesis: dipeptides or tripeptides as the ligands for signal transduction or cosmetic applications
D Amino Acid Peptides: Resistant to proteases for higher stability and special structure for peptide drug design
TFA Free Acetate Peptides: Low toxic peptides for peptide drug and cell studies
Rush Peptide Service: Receive your peptides in a week and accelerate your research
Peptide Magnetic Agarose Conjugate: Conjugate your peptide to the magnetic agarose for easy binding assay
N Terminal Acetylation: Increase peptide stability by preventing N and C-terminal degradation.
C Terminal Amidation: Neutralize negative charge created by the C-terminal COOH. Mimic native proteins, and remove hydrogen bonding which may interfere with the assays
Multiple Antigenic Peptides (MAP), Dendrimers and Dendrons: Branched peptides MAP4 or MAP8 have a high molar ratio of the peptide antigen for higher immune responses
Immunogenic Peptides: BSA, KLH or OVA Conjugation: Conjugated peptides for ELISA, antibody production applications
Peptide Library: Large scale of peptide screening for new drug candidates
Stapled Peptide, Glycosylation, and Special Amino Acids: Palmitic acid increases the cell permeability and helps the binding of the peptides to a cell membrane.
Frequently Asked Questions: Peptide Synthesis
The process of introducing medicines into cells has always proved to be a major challenge for scientists. However, CPPs have the ability to enter a cell through the plasma membrane independent of a membrane receptor. They are usually small peptides 10-30 residues in length.
