Title: Xianjin Liu: Innovator in Insecticidal Proteins
Introduction
Xianjin Liu is a prominent inventor based in Xuanwu, 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, Liu's work has the potential to revolutionize pest management strategies.
Latest Patents
Liu'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, effectively competing with Cry1Ab and Cry1Ac toxins for binding. Through indoor insecticidal biological activity assays, the protein shows a promising insecticidal effect, making it a viable alternative 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, along with an anti-Cry1B toxin idiotype single-chain antibody that has an amino acid sequence represented by SEQ ID NO.2. The idiotype single-chain antibody exhibits insecticidal activity and has binding activity to midgut peritrophic membrane specific receptor BBMV after expression by the prokaryotic system.
