SARS-CoV-2 S Protein RBD (N439K, HEK293, His)

Cat. No.: HY-P76031
Handling Instructions

The SARS-Cov-2 S glycoprotein is a SARS-Cov-2 S glycoprotein. The amino acid sequence 1261-1267a.a of the SARS-Cov-2 S glycoprotein is transmembrane. The SARS-Cov-2 S glycoprotein is a highly glycosylated trimer, each of which consists of 1260 amino acids (residues 14-1273), divided into four structural domains: the n-terminal domain (NTD), the c-terminal domain (CTD, also known as the receptor-binding domain, RBD), and two subdomains (SD1 and SD2). SARS-CoV-2 S Protein RBD (N439K, HEK293, His) is the recombinant Virus-derived SARS-CoV-2 S protein RBD, expressed by HEK293 , with C-His labeled tag. The total length of SARS-CoV-2 S Protein RBD (N439K, HEK293, His) is 223 a.a., with molecular weight of ~26.6 kDa.

Background

SARS-Cov-2 is a enveloped positive-sense single-stranded RNA virus that causes COVID-19.
SARS-CoV-2 possesses four structural proteins, namely the envelope protein (E), spike or surface glycoprotein (S), membrane protein (M), and nucleocapsid protein (N).
The SARS-Cov-2 S glycoprotein is located on the exterior of the viral particle, giving the coronavirus its crown-like appearance.
The SARS-Cov-2 S glycoprotein can mediate the attachment and entry of viral particles into host cells and is an important target for vaccine development, antibody therapy, and antigen-based diagnostic esting[1][2][3][4][5].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
