摘要/描述

We present herein a novel method of pIII-based antibody phage display using Hpd3cells—bacterial cells bearing the genome of a gene-III-lacking helper phage (VCSM13d3). A high level of single-chain variable fragments (scFvs) was displayed in the consequent phagemid particles using Hpd3cells to rescue the phagemid encoding scFv-pIII. Hpd3cells considerably improved the specific enrichment factor when used for constructing an immunized antibody library. In addition, using Hpd3cells could overcome pIII resistance and can contribute to the efficient enrichment of specific binding antibodies from a phage display library, thereby increasing the chance of obtaining more diverse antibodies specific for target antigens.
