General description
Cytomegalovirus (CMV) is a prototype b-herpes virus that is ubiquitously distributed in the human population and is known to cause silent pandemic in immunocompromised subjects. Following a primary infection, which is usually asymptomatic, the virus can establish a latent infection and can be re-activated. The CMV replication cycle has three distinct phases that are designated as immediate early (TE), early (E) and late (L). The immediate early antigens are 72 kDa IE1 and 86 kDa IE2 phosphoproteins that are the first de novo synthesized proteins following primary CMV infection or re-activation. They play an important role in the immune response and are recognized by specific T cells. While IE2 is reported to be absolutely indispensable for productive viral replication, IE1 is only conditionally essential and appears to synergize with IE2 to promote transcriptional activation of the viral early genes. Although IE2 is the principal transcriptional activator of the CMV early genes, it can also negatively regulate viral gene expression after low infection. IE2 is also shown to block virus-induced expression of several inflammatory chemokines, including IL-8, MCP-2, MIG, MIP-1a, and RANTES. It also blocks host cell DNA replication. Both, IE1 and IE2 are reported to delay cell death in infected cells and even block apoptosis. Ectopic IE1 is shown to trigger a p53-dependent G1 growth arrest response, while it induces quiescent cells to enter S phase in p53-negative cells. IE1 also shown to antagonize the type I interferon by interfering with Jak-STAT signaling. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Anti-Cytomegalovirus, clone 8B1.2 ZooMAb®, Cat. No. ZMS1015, is a recombinant Mouse monoclonal antibody that detects immediate early antigen in cytomegalovirus infected cells and is used in ELISA, Immunocytochemistry, and Immunohistochemistry (Paraffin).
Biochem/physiol Actions
Clone 8B1.2 is a ZooMAb® mouse monoclonal antibody that detects immediate early antigen in cytomegalovirus infected human cells.
Physical form
Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb® formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
