Production of a polyclonal antibody to the VP26 nucleocapsid protein of white spot syndrome virus (wssv) and its use as a biosensor

Suchera LOYPRASERT-THANANIMIT, Akrapon SALEEDANG, Proespichaya KANATHARANA, Panote THAVARUNGKUL, Wilaiwan CHOTIGEAT

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 216-223 doi: 10.1007/s11705-012-1289-y

Abstract: White spot syndrome virus (WSSV) is a major cause of high mortality in cultured shrimp all over the world. VP26 is one of the structural proteins of WSSV that is assumed to assist in recognizing its host and assists the viral nucleocapsid to move toward the nucleus of the host cell. The objective of this work was to produce a polyclonal antibody against VP26 and use it as a biosensor. The recombinant VP26 protein (rVP26) was produced in (BL21), purified and used for immunizing rabbits to obtain a polyclonal antibody. Western blot analysis confirmed that the antiserum had a specific immunoreactivity to the VP26 of WSSV. This VP26 antiserum was immobilized onto a gold electrode for use as the sensing surface to detect WSSV under a flow injection system. The impedance change in the presence of VP26 was monitored in real time. The sensitivity of the biosensor was in the linear range of 160–160000 copies of WSSV, indicating that it is good and sensitive for analysis of WSSV. The specificity of the biosensor was supported by the observation that no impedance change was detected even at high concentrations when using Yellow Head Virus (YHV). This biosensor may be applied to monitor the amount of WSSV in water during shrimp cultivation.

Decontamination of Cr(VI) facilitated formation of persistent free radicals on rice husk derived biochar

Kaikai Zhang, Peng Sun, Yanrong Zhang

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 2, doi: 10.1007/s11783-019-1106-7

Abstract:

PFRs were produced on biochar during Cr(VI) decontamination.

PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI).

Appearance of excessive oxidant led to the consumption of PFRs on biochar.

Biochar charred at high temperature possessed great performance to Cr(VI) removal.
