Choose the optimal multivalent peptide architecture for repeated epitope presentation, higher-order branching, multiepitope integration or dual-target recognition—supported by custom design, synthesis, purification, modification and analytical characterization.
Multivalent peptides place multiple peptide motifs, epitopes or recognition domains within one defined molecular architecture. The correct format depends on whether the project requires repeated copies of one epitope, generation-based branching, integration of different epitopes or coordinated recognition of two targets.
This overview organizes Bio-Synthesis capabilities into four clear sub-platforms: Multiple Antigen Peptides (MAPs), Dendrimer Peptides, Multiepitope Peptides and Bispecific Peptides. Each addresses a distinct design objective and should be selected according to valency, spatial arrangement, sequence composition, epitope accessibility, purification strategy and analytical feasibility.
Before synthesis, our scientists review the architecture, branch-point chemistry, peptide-arm identity, spacer design, functional-handle placement and proposed release criteria.
Compare the defining advantage and most common starting application for each platform.
Vaccines & antibody research
Delivery & receptor clustering
Immunology & vaccine design
Targeted binding & molecular bridging
Select the primary design objective to see the most suitable starting architecture.
Best suited to the repeated display of one peptide sequence on a defined lysine-core scaffold.
Best suited to generation-defined branching, higher valency and multifunctional display.
Best suited to combining several distinct epitopes or functional peptide domains within one construct.
Best suited to integrating two distinct recognition or binding functions within one construct.
Compare four distinct architecture strategies. Each card is clickable and opens its dedicated platform page.
Lysine-core MAP2, MAP4 and MAP8 architectures that present repeated copies of an epitope for carrier-free immunogen design, antibody research and multivalent binding studies.
Higher-order branched peptide scaffolds with generation-defined valency and multiple terminal groups for receptor clustering, targeting, delivery, imaging and biomaterials research.
Linear, branched, MAP-based or hybrid constructs that combine two or more distinct epitopes or functional peptide domains within one chemically defined construct.
Engineered constructs containing two distinct recognition or functional domains for dual-target recognition, molecular bridging, receptor engagement and coordinated binding studies.
Select a platform to examine its molecular organization, defining design features and common application space. The schematics are conceptual and are not drawn to scale.
MAP architectures present multiple copies of the same peptide sequence from a branched lysine scaffold. Defined MAP2, MAP4 and MAP8 formats support dense epitope presentation without requiring a conventional carrier protein.
Peptide dendrimers use iterative branching to create higher-order architectures with a controlled branching generation, terminal-group density and multifunctional presentation. Their design can support receptor clustering, delivery and modular surface functionalization.
Multiepitope peptides combine different B-cell epitopes, T-cell epitopes or functional peptide domains in a single linear, branched or hybrid design. Linker selection and domain order are tailored to preserve accessibility and intended biological function.
Bispecific peptides integrate two distinct binding or recognition functions within one construct. Spacer length, linker chemistry and domain orientation are selected to support simultaneous or sequential target engagement.
Use the visual comparison for rapid orientation, then review the primary objective and main planning consideration for each architecture. Select the platform according to the intended biological function rather than branch number alone.
