Conjugué: Inconjugué

Application: ELISA, Western Blotting (WB), Immunofluorescence (IF), Flow Cytometry (FACS), Fluorescence in situ hybridization (FISH), Immunohistochemistry (IHC)

Specificité: Detects the Nucleocapsid (N), Omicron, and BA.2 sub-variant.

Réactivité croisée (Details): BLAST analysis was used to suggest reactivity with related Coronavirus proteins. Cross reactivity with homologues from other sources has not been determined.

Homologie: Predicted reactivity based on immunogen sequence: SARS-CoV2 Nucleocapsid protein: (homology 90%)

Purification: This protein A purified antibody is directed against SARS Coronavirus Nucleocapsid (N) protein. The product was purified from monospecific antiserum by protein A affinity purification.

Immunogène: This protein A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a purified recombinant protein corresponding to full length SARS Coronavirus Nucleocapsid protein. Lifesensors Inc. prepared the Nucleocapsid protein as follows: SUMO-Nucleocapsid fusion was expressed in E.coli in LB medium and purified using using Ni-NTA resin (Qiagen) affinity chromatography. After the fusion was cleaved by the SUMO Protease (LifeSensors), the SUMO tag and protease were subtracted from the nucleocapsid using MAC and the nucleocapsid was finally purified using Cation Exchange Chromatography with the Macro-Prep High S resin (BioRad) and size exclusion chromatography.

Information d'application

Indications d'application: ELISA : 1:10,000 - 1:50,000

This protein A purified antibody has been tested for use in ELISA, western blot, Immunohistochemistry, Immunofluorescence, and lateral flow. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 46 kDa in size corresponding to SARS Nucleocapsid (N) protein by western blotting in the appropriate cell lysate or extract. ELISA and lateral flow format has been used to detect virus in extracts from nasal and throat swabs and saliva. IF has been used to determine the presence or absence of virus entering cells especially when anti-viral drugs are applied. IHC studies have been performed on biopsies, included retrospective studies on cadaver tissues after formalin fixation and paraffin embedding, detecting the coronavirus in lung, liver, bile duct, and placenta tissue. Yet other studies have shown this antibody has the ability to neutralize the virus and thereby protect cells from the uptake of live virus. Others have demonstrated the utility of the antibody in flow cytometry studies.
