    Multiple Disulfide Bonds

    Disulfide bridge bond plays an important role in the stability of protein structure. ABclonal Peptide™ is able to build up to four disulfide bridges between cysteine at specified positions on one peptide.

  • 5
    Multiple Phosphorylations

    ABclonal Peptide™ can synthesize serine-, threonine-, and tyrosine-phosphopeptides. For peptides containing one or more of these hydroxy-amino acids, selective phosphorylation can be achieved by orthogonal protection or by Fmoc-protected phosphorylated amino acids. Now we have been able to provide four phosphorylated sites modified peptides.

  • 6
    Keyhole Limpet Hemocyanin (KLH),Bovine Serum Albumin(BSA), and Ovalbum

    To generate significant immune responses, peptides are conjugated to bigger carrier proteins, such as ovalbumin, or BSA or KLH. ABclonal Peptide™ couples the cysteine residue of the peptide to the carrier protein.

  • 7

    PEGylation is the covalent conjugation of macromolecules with polyethylene glycol (PEG), polymers that are nonionic, nontoxic, biocompatible and highly hydrophilic. PEGylation enhances the therapeutic application of macromolecules.

  • 8
    Isotope Labeling

    ABclonal Peptide™ can label peptides with stable nonradioactive isotopes, such as 2H, 15N, 13C, or both 15N and 13C. isotope labeled peptides are mainly used in medical and biological fields at higher prices, In order to meet the needs of customers, we accept micrograms isotope labeling peptide customization.

  • 9
    Multiple Antigenic Peptide(MAP) syste

    Multiple antigenic peptides, consisting of highly localized peptide density and high molecular weight, is one potent way to produce high-titer antipeptide antibodies and synthetic peptide vaccines. This system utilizes lysine to form a backbone to which multiple peptide chains can be attached. ABclonal Peptide™ can form Asymmetric 4 branches and Asymmetric 8 branches.
