Preparation of recombinant glycoprotein B (gB) of Chelonid herpesvirus 5 (ChHV5) for antibody production and its application for infection detection in sea turtles.

The Chelonid herpesvirus 5 (ChHV5) infection possibly associated to the fibropapillomatosis (FP) disease in sea turtles worldwide remains largely unknown and limited studies have used serological approaches to detection of antibodies against ChHV5 in sea turtles with or without FP. We aimed to develop diagnostic platforms based on the viral glycoprotein B (gB) for ChHV5 infection. In this study, five recombinant sub-fragments of the gB protein were successfully expressed and subsequently served as antigens for both seroprevalence and antibody production.

Construction of a microrobot system using magnetotactic bacteria for the separation of Staphylococcus aureus.

Magnetotactic bacteria exhibit superiority over other bacteria in fabricating microrobots because of their high motility and convenient controllability. In this study, a microrobot system is constructed using magnetotactic bacteria MO-1 and applied in pathogenic separation. The feasibility of this approach is demonstrated using Staphylococcus aureus.

Potent neutralization of influenza A virus by a single-domain antibody blocking M2 ion channel protein.

Influenza A virus poses serious health threat to humans. Neutralizing antibodies against the highly conserved M2 ion channel is thought to offer broad protection against influenza A viruses. Here, we screened synthetic Camel single-domain antibody (VHH) libraries against native M2 ion channel protein.

[Construction of human CXCR3B gene transfected cell line, identification and study of its biological function].

Aim: To construct recombinant human CXCR3B gene expression vector and obtain L929-CXCR3B gene transfected cell line for stably expressing human CXCR3B.

Methods: Human CXCR3B gene of full length was amplified by PCR from the plasmid pMD19-T/huCXCR3A. Then, it was inserted into eukaryotic expression vector pIRES2-EGFP to construct recombinant vector pIRES2-EGFP/huCXCR3B.

[Construction of murine CXCR3 gene transfected cell line, identifiction and study of its biological function].

Aim: To construct recombinant murine CXCR3 gene retroviral vector and obtain L929-mCXCR3 gene transfected cell line for stably expressing murine CXCR3. We further study on L929-mCXCR3 migration effect resulted from interaction by CXCR3 and its ligand IP-10.

Methods: One female BALB/c mouse (7 weeks) was injected with 0.
