Purification	Affinity purification
Endotoxin	<1.0 EU/ug determined by the LAL method
Formulation	PBS, pH7.4
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.
SDS-PAGE
Predicted Molecular Weight	13.5 kDa
Storage Condition	Aliquot and store at -20℃ to -80℃. Avoid repeated freezing and thawing cycles.
Shipping Condition	In general, the proteins are provided as lyophilized powder which are shipped at ambient temperature. They are shipped out in dry ice if supplied in liquid form.
Uniprot ID	Q6GR94#function
Function	Inhibitory receptor acting as a major negative regulator of T-cell responses. The affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28.
