 Biological Activity    The activity was tested y immobilized recombinant CD80 (1ug/ml) ability to bind recombinant mouse CD28 in functional ELISA.
Section Bar
 Preparation and Storage    Recombinant mouse CD80, as supplied, can be stored in working aliquots at 2 degree - 8 degree C for one month, or at -20 degree C to -70 degree C for twelve months.

Avoid repeated freeze/thaw cycles.
 Other Notes    Small volumes of CD80 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Related Product Information for CD80 recombinant protein

   CD80 is a monomeric surface protein found on activated APCs. The extracellular region of CD80 consists of two highly glycosylated Ig- like extracellular domains, which have defined regions for binding its ligands, CD28 or CTLA-4, on T cells.One ligand of CD80, CD28, provides critical costimulatory signals to activated T cells to increase cytokine production, cell proliferation, and cell viability, while the other ligand, CTLA-4, may mediate a growth-inhibitory signal.The same regions of CD80 are involved in binding to both CD28 and CTLA-4, but CTLA-4 binds to CD80 with about a 20-fold higher avidity than CD28 does. This suggests that low levels of CTLA-4 expressed on the cell surface can compete for CD80 binding even when CD28 is expressed at much higher levels.
