Recombinant Virus Influenza A nucleoprotein Protein Summary

A cDNA coding for Human Influenza-A (Influenza A virus (A/Puerto Rico/8/34/Mount Sinai (H1N1)) segment 5) nuclear protein NP was cloned into a Baculovirus expression vector. The recombinant HNP-A was purified by proprietary chromatographic techniques.
Protein/Peptide Type
Recombinant Protein


  • SDS-Page 2-10 ug/lane
Application Notes
This protein migrates as a 55 kDa band in SDS-PAGE. Use in Immunohistochemistry-Paraffin reported in scientific literature (PMID 24657788). The protein concentration was estimated in a BioRad assay. The absolute purity of the recombinant protein preparation has not been established.
Theoretical MW
55 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
