MOUSE ANTI-TICK-BORNE ENCEPHALITIS VIRUS NS1 (M839)

Tick-borne Encephalitis Virus NS1 antibody (clone M839), is a mouse monoclonal antibody that recognises NS1 protein from Tick-borne Encephalitis virus (TBEV). This antibody recognises TBEV NS1 in ELISA and Western blotting assays.The antibody does show some cross reactivity with Powassan Virus NS1 in ELISA assays.  The antibody also cross reacts with Japanese Encephalitis Virus, Dengue Virus and Zika Virus NS1 proteins in Western blotting.

BACKGROUND

Tick-borne encephalitis virus (TBEV) belongs to the genus Flavivirus, of the family Flaviviridae. The virus is primarily transmitted through the bite of infected hard ticks, of the family Ixodidae. Small rodents are the primary hosts for TBEV with humans acting as accidental hosts. The virus can also be transmitted to humans through unpasteurized milk in areas where TBEV is prevalent (CDC).

TBEV is a neurotrophic virus that causes tick-born encephalitis (TBE) in humans, affecting the central nervous system (CNS). TBE is endemic in many parts of Europe, China, Mongolia and the Russian Federation and is the most common tick-born CNS infection in these. Three subtypes of TBEV have been recognised that cause tick-borne encephalitis, which are European, Far-Eastern and Siberian.

TBEV infection is asymptomatic in most cases with some individuals presenting with influenza-like symptoms. In symptomatic cases, TBEV infection typically presents as meningitis, encephalitis or meningoencephalitis. A high percentage of acute TBE cases may also develop post-encephalitic syndrome with long-lasting neuropsychiatric symptoms or neurological dysfunction (Bogovic, P).

Diagnosis of TBE infection is primarily based on clinical presentation and serological testing for TBEV specific IgM and IgG antibodies in the patient’s serum and cerebrospinal fluid. There is no anti-viral treatment for TBEV. However, several effective vaccines for TBEV are currently available which are based on European and Far-Eastern strains of the virus (WHO).
