• Gold/Silver Nanoparticles Conjugation Service

Scientific research on nanoparticles (NPs) is intense as they have many potential applications in medicine, physics, optics, and electronics. NPs can be used to deliver a cargo, such as an anticancer drug, or a cohort of radionuclide atoms to a targeted region of the body.

• Peptides-Carraier Protein Conjugation

Allow the induction of a B-cell response to the entire immunogen, including the peptide. New synthetic peptides thus offer promise as vaccines.

• Peptide-oligonucleotide Conjugation

Conjugated oligonucleotides and peptides by covalent attachment can enhance the function of the oligonucleotide. Studies have shown that peptide and oligonucleotide conjugates have stronger target cell penetration and higher cell absorption efficiency than unmodified oligonucleotides.

• Peptide-enzyme Conjugation

Peptide enzyme conjugates can detect immune complexes by visual or spectrophotometry as sensitive probes. Enzyme labels provide the best overall performance, high sensitivity, low background, and can achieve fast detection.

• Peptides-Metal Chelates Conjugation

Peptides-Metal Chelates Conjugation is a kind of compound with cyclic structure which is formed by chelation reaction between peptide and metal ions. It can improve the bioavailability of metal ions by means of the absorption mechanism of peptides in the body, and has physiological and biochemical characteristics that inorganic metal ions do not have.

• Peptides-Fatty Acids Conjugation

Peptides-Fatty acids Conjugation is obtained by fatty acid modification of the main chain structure or contralateral chain group of polypeptide drugs, which can also be used for a number of different applications, for example, improving drug solubility and absorption, prolonging the half-life of peptide drugs in the circulation and enhancing plasma albumin binding rate.

• NHS-Activated Peptide Conjugation Magnetic Beads

NHS-Activated Peptide Conjugation Magnetic Beads, also called immunomagnetic microspheres, is a small spherical particle with superparamagnetic and protective shell, which is mainly used in the field of separation and purification, such as protein separation and purification, antibody separation and purification.

• Peptides-Imaging Agents Conjugation

Peptide-imaging agent conjugation is a molecular probe that can be used for organ, tissue, or molecular imaging. After peptide-imaging agent conjugation is introduced into the body, it can concentrate in the target organ or tissue, detect the radiation emitted by the imaging instrument, and obtain the distribution image of the drug in the body, which can be used to diagnose various diseases.

• Peptides-Fatty Acids Conjugation

To improve peptide pharmacokinetics, conjugating the peptide to lipids is a favored approach. Peptides-Fatty acids conjugation is obtained by fatty acid modification of the main chain structure or contralateral chain group of polypeptide drugs.

• Peptide-small-molecule Conjugation

Peptide can be coupled with various small molecules, such as fluorophores, chelating agents, and therapeutics. Peptide-small-molecule conjugates have the characteristics of good selectivity, low immunogenicity, good biocompatibility, strong permeability, and easy excretion, which can be used in tumor-targeted molecular diagnosis.

• Peptide-Antibody Conjugation

Peptide-Antibody Conjugation technology can further improve the accuracy of peptide delivery based on the guidance of antibodies and facilitates the delivery of conjugate aprotinin-derived peptides across the blood-brain barrier.

• Peptide-siRNA Conjugation

Peptide-siRNA Conjugation technology is to use peptides as a carrier of nucleic acids to bring short siRNA into the body, exert its gene silencing effect, and specifically silence the expression of target genes to achieve therapeutic purposes.

• Peptide-DNA Conjugation

Peptide-DNA conjugates are molecular chimeras composed of nucleic acid moieties covalently attached to polypeptide parts and are used in a variety of applications such as therapy and nanotechnology. A common strategy is to combine a cell-penetrating carrier peptide with a phosphorosulfate DNA chain that enhances the nuclease attack ability.

• Peptide-RNA Conjugation

Peptide-RNA conjugate is considered a useful drug because its stability is much better than RNA. Methods for preparing peptide-RNA conjugates include: post-synthesis coupling method (or post-assembly coupling method and fragment coupling method), fully stepwise synthesis method (or online solid-phase synthesis method), natural coupling method and template orientation coupling method.
