Nucleocapsid protein, NP, Protein N

Source

SFTS virus Nucleocapsid Protein, His Tag (NUN-S5243) is expressed from human 293 cells (HEK293). It contains AA Ser 2 - Leu 245 (Accession # AJO16088.1).

Predicted N-terminus: His

Molecular Characterization

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 28.8 kDa. The protein migrates as 33-37 kDa and 48-55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, 0.2 M Arginine, pH7.4 with trehalose as protectant.

バックグランド

The nucleocapsid (NP) protein of Severe Fever with Thrombocytopenia Syndrome virus (SFTSV) is encoded by the S segment of its tripartite RNA genome. NP plays a central role in viral replication by encapsidating the genomic RNA and forming ribonucleoprotein complexes with the polymerase. It is highly conserved among SFTSV strains and strongly immunogenic, making it a major target for diagnostic assays and serological studies. Because of its abundance and stability, recombinant NP is widely used as an antigen for ELISA, rapid tests, and antibody development against this emerging tick-borne phlebovirus.
