产品介绍 Product Description

General 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.

Biochem/physiol Actions

Clone 2F13 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects 2A peptide tagged proteins.


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.


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.
