Measured by its ability to neutralize CMV UL146/vCXC1-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR2. The Neutralization Dose (ND50) is typically 10-30 µg/mL in the presence of 0.3 µg/mL Recombinant Viral CMV UL146/vCXC1.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Chemotaxis Induced by CMV UL146/vCXC1 and Neutralization by CMV UL146/vCXC1 Antibody.
Recombinant Viral CMV UL146/ vCXC1 (Catalog # 620‑CM) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CXCR2 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Viral CMV UL146/vCXC1 (0.3 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Viral CMV UL146/ vCXC1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF620). The ND50 is typically 10‑30 µg/mL.

Cytomegalovirus (CMV), a member of the beta herpesvirus subfamily, typically causes subclinical or latent infections in the normal adult population. However, CMV can cause congenital disease during pregnancy and is a human opportunistic pathogen that affects immunocompromised individuals. Virulent CMV clinical isolates have also been shown to carry at least 19 genes, designated UL133 - UL151, that are not found in laboratory strains that have lost virulence characteristics. Two of these genes, UL146 and UL147, exhibit sequence similarity to CXC chemokines.
