Neuraminidase subtype N2 (amino acids 30 - 461) from Influenza A virus subtype H9N2 (A/Bat/Egypt/381OP/2017). The protein is equipped with a c-terminal FLAG-tag and was expressed in Expi293 cells. Purification was performed using FLAG-M2 affinity chromatography followed by dialysis against 1X PBS pH 7.4.
Recombinant receptor binding domain of Bovine coronavirus strain L9 (amino acids 311 - 695 of the Spike protein) . The protein was expressed in Expi293 cells and Streptactin-purified. It is equipped with a c-terminal SpyTag (RGVPHIVMVDAYKRYK) and a single StrepTag
E2 glycoprotein of the Norway rat pestivirus isolate NrPV/NYC-D23; amino acids 803 - 1150 of the polyprotein. C-terminally, a single StrepTag was added. The protein was expressed in Expi293 cells and purified by Streptactin affinity chromatography.
