|Recombinant Human B7-2/CD86 (C-6His)|
|Description||Recombinant Human CD86 is produced by our Mammalian expression system and the target gene encoding Ala24-Pro247 is expressed with a 6His tag at the C-terminus.|
|Names||T-Lymphocyte Activation Antigen CD86, Activation B7-2 Antigen, B70, BU63, CTLA-4 Counter-Receptor B7.2, FUN-1, CD86, CD28LG2|
|Formulation||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 ddH2O.
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 reducing SDS-PAGE.|
|Endotoxin||Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.|

|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.|
