Target description
Capsid protein (UniProt: P03612; also known as CP, Coat protein) is encoded by the Cp gene (Gene ID; 1260899) in Enterobacteria phage MS2. MS2 is a small RNA bacteriophage that infects E. coli and other members of the Enterobacteriaceae family. Its genome consists of a single sense (+) strand of RNA 3569 nucleotides in length, which encodes only four proteins: the coat protein, the A or maturation protein that is required for infectivity, a subunit of the viral replicase, and a small lysis protein encoded in an overlapping reading frame. The capsid protein acts as a translational repressor of viral replicase synthesis late in infection. This latter function is the result of capsid protein interaction with an RNA hairpin which contains the replicase ribosome-binding site. Capsid protein self-assembles to form an icosahedral capsid with a T=3 symmetry that is about 26 nm in diameter and consists of 89 capsid proteins dimers (178 capsid proteins). Capsid protein is shown to be a homodimer that can form dimers that assemble by group of 5. Twelve such pentamers are linked together with free dimers. The homodimers bind to the viral RNA via an operator hairpin. It also binds to many other RNA sequences in the viral genome and this interaction probably shifts the virus from the replicative to the assembly phase and ensures specific encapsidation of the viral genome. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form
Purified recombinant rabbit 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.
Reconstitution
30 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
Storage and Stability
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.
