detection of lassa virus antinucleoprotein immunoglobulin g (igg) and igm antibodies by a simple recombinant immunoblot assay for field use. | the nucleoprotein of lassa virus, strain josiah, was expressed in escherichia coli as an n-terminally truncated, histidine-tagged recombinant protein. following affinity purification the protein was completely denatured and spotted onto nitrocellulose membrane. a total of 1 microgram of protein was applied for detection of lassa virus antibodies (lva) in a simple immunoblot assay. specific anti-lassa immunoglobulin m (igm) antibodies could be detected by increasing the amount of protein to 5 mic ... | 1998 | 9774554 |
