General description

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This antibody is Preservative-free, produced without the harm or sacrifice of animals and exceptionally stable to allow for ambient shipping and storage if needed and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency". Click here for more information.
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Target description

Genome polyprotein (UniProt: P03305) is encoded by the D1Y31_gp1 gene (Gene ID: 37627025) in Foot-and-mouth disease virus. Following its synthesis, it is cleaved into 15 different chains. P2A chain resides in the amino acids 936-953 in the internal region. 2A peptides and 2A-like peptide sequences (known as cis-acting hydrolase elements or CHYSEL) are a superior alternative to internal ribosomal entry sites (IRES) for coordinating the expression of multiple gene products from a single recombinant construct. The 2A sequences are relatively short peptides of about 16-20 amino acids (depending on the virus of origin). They contain a highly conserved sequence, GDVEXNPGP, at the C-terminus, which is shared by different 2As and is essential for the creation of steric hindrance and ribosome skipping. These peptides allow multiple proteins to be encoded as polyproteins, which then dissociate into component proteins upon translation. The 2A sequence impairs normal peptide bond formation via a mechanism called ribosomal skipping, which results in effective, non-enzymatic generation of distinct peptide products from a single multi-cistronic construct. These peptides are used by several families of viruses, the best-known amongst these are foot-and-mouth disease virus 2A (F2A) and Thosea asigna virus 2A (T2A). This antibody reacts with protein in lysate from HEK293T cells transfected with various 2A-tagged proteins. This ZooMAbZooMAb® 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, 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

300 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.
