Storage |
Lyophilized protein should be stored at < -20C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7C for 2-7 days. Aliquots of reconstituted samples are stable at < -20C for 3 months. |
Description |
Recombinant Human Cytotoxic T-lymphocyte protein 4 is produced by our Mammalian expression system and the target gene encoding Lys36-Asp161 is expressed with a Fc tag at the C-terminus. |
Product State |
Lyophilized |
Formulation Description |
Lyophilized from a 0.2 um filtered solution of PBS, pH7.4. |
Reconstitution |
Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
Purity |
Greater than 95% as determined by reducing SDS-PAGE. |
Endotoxin |
Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. |
Background |
Cytotoxic Tlymphocyte 4(CTLA-4, CD152), is a type I transmembrane T cell inhibitory molecule that is a member of the Ig superfamily. Human or mouse CTLA4 cDNA encodes 223 amino acids (aa) including a 35 aa signal sequence, a 126 aa extracellular domain (ECD) with one Ig-like V-type domain, a 21 aa transmembrane (TM) sequence, and a 41 aa cytoplasmic sequence.It is widely expressed with highest levels in lymphoid tissues. CD28 and CTLA-4, together with their ligands, B7-1 and B7-2, constitute one of the dominant costimulatory pathways that regulate T and B cell responses. CD28 and CTLA-4 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T Cells and may play an important role in their functions. Tcell activation through the Tcell receptor and CD28 leads to increased expression of CTLA4. |
