VRP-1487 Recombinant Adenovirus E4ORF1-11R Protein $300

Recombinant Adenovirus E4ORF1-11R Protein

Product Name: Recombinant Adenovirus E4ORF1-11R Protein
Catalog #:  VRP-1487
Manufacture:  LD Biopharma, Inc.

Adenovirus E4 mRNA contains 7 ORFs, suggesting that E4 encodes at least 6 gene products (E4ORF1–E4ORF6/7). Among the known E4 ORFs, E4ORF1 primarily affects survival but not cell proliferation. Recent data indicated that by transfection of E4ORF1 gene into human primary endothelial cells (PECs), it facilitate organ-specific purification of PECs, while preserving their vascular repertoire for months in serum/ cytokine free culture.

Full-length adenovirus E4orf1 (128 aa) gene was constructed by DNA synthesis using codon optimization technology with 29 aa N-terminal T7 / His / TEV cleavage site Tag and 11R tag at C-terminal. It was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
