Anti-2A Peptide Antibody

2A peptides and 2A-like peptide sequences (also known as CHYSEL, or cis-acting hydrolase elements) are a superior alternative to internal ribosomal entry sites (IRES) for coordinating the expression of multiple gene products from a single recombinant construct. 2A 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, resulting in effective, non-enzymatic generation of distinct peptide products from a single multicistronic construct. The use of 2A sequences allows the stoichiometric production of up to four proteins from a single vector, making it a powerful tool for the equimolar expression of multiple cistrons.

Recognizes the 2A sequence, derived from Foot and Mouth picornavirus (VKQTLNFDLLKLAGDVESNPG*P), where * represents the 2A cleavage site. The epitope is believed to be within the “GDVESNPG” region since the antibody also recognizes the unrelated 2A regions from Thosea asigna virus and Equine rhinitis A virus.

Serum with 0.05% NaN3.

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Control
2A-containing recombinant proteins

Western Blot Analysis:
A multicistronic vector was synthesized consisting of several CD3 proteins linked with 2A peptide sequences from foot and mouth disease, Thosea asigna, and Equine rhinitis A viruses, respectively (CD3δ-F2A-CD3ε-T2A-CD3γ-E2A-CD3ζ)1. The vector was transduced in 293 cells. A 1:1000 dilution of this antibody detected the 2A sequence in all three CD3-2A proteins (CD3 epsilon, gamma, delta) generated from a single 2A peptide-linked retroviral vector.
