| Protein Name / Synonyms | Nucleocapsid Protein, N Protein |
| Expressed Region | Met1-Ala419, containing 4 deletions (P13L, E31del, R32del, and S33del) and 2 mutations (R203K, G204R). |
| Expression System | HEK293 cells |
| Tag | C-terminal His-tag |
| Purification | His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC) |
| Purity | >90% |
| Purity Determined By | SDS-PAGE under reducing conditions and visualized by Coomassie blue staining |
| Molecular Weight (kDa) | Recombinant protein product has a calculated molecular mass of 47 kDa. Due to the abundant glycosylation, it migrates as approximately 55 kDa major protein band in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. The minor small protein bands (25-30 kDa) likely the cleaved products. See deglycosylation analysis image below. |
