Antibody Plasmid Construct Design

Creating a recombinant antibody involves a detailed procedure, essential for its successful expression. After selecting and refining the antibody's sequence, scientists need to pick a suitable expression vector backbone. They must carefully consider vital elements to incorporate in the vector, such as a promoter, signal peptide, and linker peptides, in addition to other components. Here we present some consideration when designing your vector backbone.

  • VH and VL Sequences

  • Promoter

  • Signal Peptide

  • Linker Peptide

  • Purification Tags

VH (variable heavy) and VL (variable light)

Function: Determine the unique antigen-binding capabilities of recombinant antibodies, governing both specificity to antigens and binding affinity.

Considerations: It's crucial to optimize the VH and VL sequences for the chosen host cell, ensure their compatibility for assembly, and select a vector that supports robust expression.
