Human Fab phage display library construction kit

Product Overview

Fusion BioLabs offers a range of library primer sets and phagemid vector combination for antibody phage display and peptide phage display construction. With customizable features and robust performance, our primer sets and phagemid vectors are designed for facilitating phage display library generation as fast as within one week.

 

pAPD-h-Fab are the phagemid vectors for construction of a fragment antigen-binding (Fab) library for human antibodies. Here are the key steps involved in constructing such a library:

  • Amplify V genes from cDNA reverse transcript from RNA isolated from peripheral blood lymphocytes (PBL) or lymphoid tissue of non-immunized or immunized donors using PCR primers corresponding to known VH, Vκ, and Vλ gene sequences.
  • Amplify CH1 fragment, Ck fragment and Cλ fragment using pAPD-h-Fab as template.
  • Combine VH repertoires and CH1 fragment, Vk repertoires and Ck fragment, and Vλ repertoires and Cλ fragment to create VH-CH1, Vk-Ck and Vλ-Cλ constructs respectively, using a simple two-fragment PCR assembly procedure.
  • Overlap assembly Vk-Ck and VH-CH1, and Vλ-Cλ and VH-CH1 to make Fab repertoires respectively.
  • Restriction enzyme digestion pAPD-h-Fab vector and Fab repertoires with SfiI.
  • Ligation of digested and purified repertoires into digested and purified pAPD-h-Fab vector to make human Fab libraries.

 

Key Features

High expression efficiency: Engineered for efficient expression and display of antibody fragment scFv on the surface, allowing for easy screening and selection of target molecules.

Flexibility and versatility: One vector for both antibody library construction and downstream antibody fragment expression. No need subcloning into expression vector for downstream application.
