Function

Following virus entry into host cell, provides nuclear import of HDV RNPs thanks to its nuclear localization signal. Needs co-infection with hepatitis B virus to provide surface proteins, otherwise there is no packaging or budding. Packages the HDV ribonucleoprotein in hepatitis B virus empty particles.

Biological Context

Subcellular Location: Virion; Host nucleus, host nucleolus

Product Specifications

Recombinant Hepatitis delta virus genotype II Large delta antigen is a recombinant protein from Hepatitis delta virus genotype II (isolate Japanese S-1) (HDV), expressed in E.coli, covering amino acids 1-211aa, with C-terminal 6xHis-tagged tag, molecular weight 30.8kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.
