Recombinant HCoV-229E N Protein (Met1-Asn389), C-His tagged, Animal-free, Carrier-free

• Cat.No.: N-336H
• Product Overview: Recombinant Human coronavirus 229E N Protein (Met1-Asn389) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Species: HCoV
• Source: E.coli
• Tag: His
• ProteinLength: Met1-Asn389
• Description: There are seven human coronaviruses have been identified. The common human coronaviruses are four groups, known as 229E (α coronavirus), NL63 (α coronavirus), OC43 (β coronavirus) and HKU1 (β coronavirus). Because the crown-like spikes on the surface of virus, they are named for coronaviruses. HCoVs cause the respiratory tract diseases, especially severe in infants and the elderly. The spike protein controled the infection of target cells and it facilitated entry into cells by binding cellular receptors.
• Form: Lyophilized
