The protein has a predicted MW of 16.3 kDa.Due to glycosylation, the protein migrates to 21-24 KDabased on Bis-Tris PAGE result.

Lyophilized from 0.22um filtered solution in PBS (pH 7.4).Normally 5 % trehalose is added as protectant before lyophilization.

Centrifuge tubes before opening.Reconstitute no more than 1 mg/mL according to the size in deionized water.

Within 1 month, 2 to 8 °C under sterile conditions after reconstitution. 12 months from date of receipt, -20 to -80 °C as supplied. Avoid repeated freeze-thaw cycles.

Nucleocapsid protein (N) is the major viral structural component; its main function is to protect and encapsidate the viral RNA forming viral RNP complex. It is encoded by the S segment vRNA and is abundantly expressed in the cytoplasm of infected cells.
