Title: The Innovations of Chongxin Xu
Introduction
Chongxin Xu is a notable inventor based in Nanjing, China. He has made significant contributions to the field of genetic engineering and biological control, particularly in the development of insecticidal proteins. With a total of 5 patents to his name, Xu's work has the potential to impact agricultural practices and pest management.
Latest Patents
Xu's latest patents include groundbreaking inventions such as the "Human-derived insecticidal bt cry toxin mimetic." This invention provides a human-derived molecularly modified insecticidal protein, along with a preparation method and application. The amino acid sequence of the insecticidal protein CCL-CCL_scFv is shown as SEQ ID No. 1. This protein demonstrates significantly higher affinity with midgut BBMV than Cry1Ab toxin, competing with Cry1Ab and Cry1Ac toxins for binding. The insecticidal protein exhibits a good insecticidal effect, effectively replacing Cry1Ac or Cry1Ab toxin for biological control of insect pests.
Another notable patent is the "Human-derived insect-resistant gene and anti-CRY1B toxin idiotype single-chain antibody encoded thereby." This invention provides a human-derived insect-resistant gene with a nucleotide sequence represented by SEQ ID NO.1, and an anti-Cry1B toxin idiotype single-chain antibody encoded by this gene, having an amino acid sequence represented by SEQ ID NO.2. The idiotype single-chain antibody is a β-type and possesses insecticidal activity, demonstrating binding activity to midgut peritrophic membrane specific receptor BBMV after expression by the prokaryotic system.
