glycoprotein B/gB Protein, HHV-7 (Cell-Free, His)

Cat. No.: HY-P702290
Handling Instructions

Glycoprotein B (gB) is an important envelope glycoprotein that forms spikes on the viral envelope and facilitates initial attachment to the heparan sulfate moiety on the host cell surface. gB is essential for viral entry and is involved in mediating fusion between the viral and cell membranes. glycoprotein B/gB Protein, HHV-7 (Cell-Free, His) is the recombinant Virus-derived glycoprotein B/gB protein, expressed by E. coli Cell-free , with N-10*His labeled tag. The total length of glycoprotein B/gB Protein, HHV-7 (Cell-Free, His) is 800 a.a., with molecular weight of 93.5 kDa.

Background

The glycoprotein B (gB) protein is an envelope glycoprotein that forms spikes on the surface of the viral envelope. It is essential for the initial attachment to heparan sulfate moieties found on the host cell surface proteoglycans. Furthermore, gB is involved in the fusion of viral and cellular membranes, facilitating the entry of the virus into the host cell. This fusion process is mediated by a fusion machinery consisting of at least gB and the heterodimer gH/gL. Additionally, gB may play a role in the fusion between the virion envelope and the outer nuclear membrane during virion egress. It exists as a homotrimer connected by disulfide bonds and is capable of binding to heparan sulfate proteoglycans. Moreover, gB interacts with the gH/gL heterodimer.

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
