Recombinant Human CTLA4, Fc Chimera
Cat.No. : | CTLA4-1913H |
Product Overview : | Recombinant Human CTLA-4 produced inE.Coliis a homodimeric, non-glycosylated polypeptide chain containing a total molecular mass of 80 kDa. Each subunit (40kDa) is fused to a polypeptide linker to the Fc portion of Human IgG1. rHuCTLA-4 is purified by proprietary chromatographic techniques. |

Cat. No. : | CTLA4-1913H |
Description : | CTLA-4 is expressed in low copy number by T-cells only after activation, but it binds CD28-ligand with approximately 20-fold higher affinity than CD28. A soluble form of the extracellular domain of CTLA-4 has been shown to bind CD28-ligand with high avidity and to suppress T-cell-dependent antibody responses in vivo. Large doses of this soluble protein also suppress responses to a second immunization. |
Source : | E.Coli. |
Amino Acid Sequence : | The sequence of the first five N-terminal amino acids was determined and was found to be Lys-Ala-Met-His-Val. |
Form : | Purified. |
Purity : | Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Anion-exchange FPLC. |
Dimers & Aggregates : | <1% as determined by silver stained SDS-PAGE gel analysis. |
Endotoxin : | < 0.1 ng/µg (IEU/µg) of rHuCTLA-4. |
Protein Content : | Protein quantitation was carried out by two independent methods: 1) UV spectroscopy at 280 nm. 2) Analysis by RP-HPLC, using a standard solution of CTLA-4 as a Reference Standard. |
Application : | 1) Molecular standard (Western, ELISA) in studying secreted BMP-4. 2) Preparing antibodies for BMP-4 monomer. 3) Molecule standard in detecting secreted BMP-4 in reduced SDS-PAGE. |
Biological Activity : | rHuCTLA-4 is fully biologically active when compared to standards. |
Storage : | -20°C, avoid freezing and thawing cycles after reconstitution. |
