Mouse Anti-Mayaro Virus E1 (M952)

$376.65$945.11 excl. VAT

Mouse anti Mayaro virus E1 (M952) protein antibody specific for MAYV. Matched pairs available and suitable for use in sandwich ELISA. No cross-reactivity in ELISA with MAYV E2, Chikungunya virus VLP, E1 and E2, O’nyong’nyong virus VLP and Ross River virus VLP.

Matched Pair

 

Western blot: Antibody is specific for Mayaro virus-like particles (Lane 2; MAYV VLP) containing E1 protein. MAYV VLP contains capsid protein (~29kDa), Spike glycoprotein E2 (~47kDa) and Spike glycoprotein E1 (~48kDa). It did not cross-react with MAYV E2 (Lane 5; human Fc-tag, Lane 6; His-tag), Chikungunya virus VLP (Lane 9; CHIKV VLP), CHIKV E2 (Lane 3; human Fc-tag) or CHIKV E1 (Lane 8; His-tag), O’nyong nyong virus VLP (Lane 4; ONNV VLP) and Ross River virus VLP (Lane 7; RRV VLP).

ELISA: Plate was coated with 0.5µg/ml of antigens in 1X DPBS overnight at 2-8ᵒC followed by blocking for 1.5 h using 1%BSA/DPBS, 300µl/well. Plate was washed 3X using Tris wash buffer. 100µl of antibody dilution was added and plate incubated for 2h at RT, 800rpm. Washed plate 3X using Tris wash buffer. Added 100µl of Goat anti mouse IgG HRP antibody (1:5000 dilution) to all the wells and incubated for 1h at RT, 800rpm. Plate was washed 4X using Tris wash buffer and 100µl HKTMB added and incubated for ~2 min. at RT. 100µl 1M HCl was then added to stop the reaction and plate was read at 450nm. Antibody is specific for MAYV VLP in ELISA. It does not cross-react with MAYV E2, Chikungunya virus (CHIKV) VLP, CHIKV E1, CHIKV E2, O’nyong’nyong virus (ONNV) VLP or Ross River virus (RRV) VLP.

BACKGROUND

The Mayaro virus capsid is composed of 240 capsid protein copies within a lipid membrane, through which 80 capsid spike proteins penetrate. The spike proteins are composed of E2 and E1 glycoproteins, which form heterodimers shortly after translation and associate into trimers when virions assemble. The E2 glycoprotein is primarily involved in attachment to host cells while the E1 protein mediates the fusion of the virus and host cell (Choi et al., 2019). Both E1 and E2 on the surface of virions are targets of anti-MAYV antibody responses.

Since MAYV’s characterisation in 1954 on the island of Trinidad, it has caused major outbreaks in South American countries, and reports have suggested that cases of MAYV infection may be higher than previously documented owing to similarities between symptoms of the co-circulating Mayaro, Dengue and Chikungunya viruses (CDC).

The Mayaro virus (MAYV) is a positive-sense, single-stranded RNA virus, of the Alphavirus genus of the Togaviridae virus family. MAYV is closely related to other the Alphaviruses such as Chikungunya, Semliki Forest and Ross River, that also produce a dengue fever-like illness, accompanied by long-lasting arthritis.
