Human Parainfluenza Virus type 1 recombinant nucleocapsid protein (hPIV1-rNP) from S. cerevisiae, in glycerol stock

Description: human Parainfluenza Virus type 1 (hPIV1) strain C-35 full-length (524 a.a.) recombinant nucleoprotein (GenBank: ABY63595.1). Expressed in S. cerevisiae and purified from yeast lysates by ultracentrifugation in CsCl gradients under native (non-denaturing) conditions.

Quality: assembled in nucleocapsid-like particles (NLPs), which are morphologically similar to native viral nucleocapsids.

Current Lot EM picture: hPIV1-rNP preparation visualized by negative staining with uranyl acetate, magnification 71.000x


Form: formulated in glycerol stock solution (50%) in phosphate buffer.

Storage: Shipped on dry ice (shipment costs to Europe: 160 €). Store at -20ºC in liquid form (solution does not freeze at this temperature).

Concentration: 1.5-2.5 mg/ml (lot specific).

Purity: >90% as determined by SDS-PAGE.


SDS-PAGE showing hPIV1-rNP product 14-P1N-ScG at approximately 58 kDa (5 μg/lane).

Applications (tested): ELISA, Electron microscopy, Western blot, SDS-PAGE.
