Why choose peptides as loading materials?

Peptides are a class of compounds consisting of three or more amino acid molecules that form peptide bonds through dehydration condensation. Peptides are involved in various physiological functions in the body as signaling molecules such as hormones, cell growth factors, neurotransmitters, etc., and play an important role in various life activities. The molecular weight of peptides is between that of small molecule chemical drugs and protein drugs, and they are characterized by high safety, controllable quality, high specificity, and high biological activity. We provide peptide synthesis and loading services of different lengths and structures according to clients' research needs.

What are the principles and advantages of LPPS of peptides?

LPPS utilizes a fully protected amino acid unit as the starting material and continuously adds amino acids to the solution to form peptide bonds with the previous amino acid, gradually growing the length of the polypeptide chain. This method is suitable for short peptide synthesis due to its fast synthesis speed, flexibility in amino acid selection, and tolerance to special sequences and chemical modifications.

Design Highly Stable Peptide Loaded Glyconanoparticles with Us

Our comprehensive peptide-loaded glyconanoparticle formulation service includes glyconanoparticle preparation, peptide molecule selection, loading, characterization, and optimization.

Glyconanoparticle Preparation

Glyconanoparticles are composed of carbohydrates and nanomaterials that are biocompatible and able to bind to peptides and stabilize their structures. We offer various methods for preparing glyconanoparticles, such as amide coupling, nucleophilic substitution, and CuAAC.

Peptide Synthesis

Our company mainly provides biosynthesis and chemical synthesis for peptide synthesis. We select the appropriate method for preparing peptides according to the specific situation and conditions of the peptide.

Biosynthesis: For complex peptide chains, our researchers use biosynthetic methods. Biosynthetic methods mainly utilize cellular mechanisms and enzymes in organisms to synthesize peptides, including enzymatic digestion, fermentation, and genetic engineering.
Chemical synthesis: Our company provides liquid-phase peptide synthesis (LPPS) and solid-phase peptide synthesis (SPPS) services.

Loading

We provide accurate peptide loading services such as glyconanoparticle surface activation and modification, incubation, cleaning, and real-time monitoring services. Our researchers load peptide molecules onto glyconanoparticles using specific chemical or physical methods based on carbohydrate and peptide properties.

Results: This literature focuses on the study of glyconanoparticles as a peptide drug delivery system and explores their ability to protect peptides from degradation by proteolytic enzymes in plasma. The researchers designed experiments to evaluate the protective effect of the glyconanoparticle delivery system on peptide drugs, including the preparation of glyconanoparticles, loading of peptide drugs, and evaluation of their stability in plasma. The experimental results showed that the glyconanoparticles delivery system significantly improved the stability of peptides in plasma and reduced their degradation by proteolytic enzymes.
