            | Description | 
            Recombinant Human CD86 is produced with our mammalian expression system in human cells. The target protein is expressed with sequence (A24-P247) of Human CD86 fused with a polyhistidine tag at the C-terminus. |

            Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2 | 
        
        
            | Shipping | 
            The product is shipped at ambient temperature. | 
        
        
            | 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 μg/ml. 
            Dissolve the lyophilized protein in 1X PBS. 
            Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | 
        
        
            | Storage | 
            Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 
            Reconstituted protein solution can be stored at 4-7°C for 2-7 days. 
            Aliquots of reconstituted samples are stable at < -20°C for 3 months. | 
        
        
            | Purity | 
            Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. | 
        
        
            | Endotoxin | 
            Less than 0.1 ng/µg (1 IEU/µg). |

            | Background | 
            The protein is the receptor that involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. It may play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T-cells within 24 hours after activation. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation. The protein interacts with MARCH8, human herpesvirus 8 MIR2 protein, adenovirus subgroup B fiber proteins and acts as a receptor for these viruses.It is expressed by activated B-lymphocytes and monocytes and promoted by MARCH8 and results in endocytosis and lysosomal degradation.It contains 1 Ig-like C2-type(immunoglobulin-like) domainand 1 Ig-like V-type (immunoglobulin-like) domain. |
