Recombinant Anti-human ERBB2 Intrabody [(D-Arg)₉]

Name: Recombinant Anti-human ERBB2 Intrabody [(D-Arg)9]
SKU: IAB-B008(A)
Rating: 5 (1 reviews)

CAT#: IAB-B008(A)

Recombinant anti-ERBB2 intrabody linked to (D-Arg)₉ targetes to the lumen of the endoplasmic reticulum prevent the transit of EGFR or the related ErbB2 molecule to the cell surface, thereby inactivating their transforming potential, expressed in CHO cells.

Immunogen
human erb-b2 receptor tyrosine kinase 2

Host Species
human

Type
scFv-(D-Arg)₉

Cell Penetrating Peptide
(D-Arg)₉
It has been proven that polyarginine peptides composed of nine arginine amino acids (Arg-9) are able to translocate across cells very efficiently. This raises the question if molecular dynamics simulations would show a similar pathway for this highly hydrophilic and charged peptide as predicted for the Tat peptide. The simplicity of Arg-9 over other CPPs also helps isolate the role of the Arg sidechain on the translocation without the effect of other sidechains. Therefore, in this work we study computationally the translocation of Arg-9 through a lipid bilayer and show that the translocation mechanism is the same as for the Tat peptide.
