CD28 Protein, Mouse (Biotinylated , HEK293, His-Avi)
CD28 Protein, a crucial regulator of T-cell activation, promotes cell proliferation, cytokine production, and T-cell survival. It enhances IL4 and IL10 production when combined with TCR/CD3 ligation and CD40L costimulation. CD28 Protein exists as a disulfide-linked homodimer and interacts with DUSP14, CD80/B7-1, CD86/B7-2/B70, and GRB2 (By similarity). CD28, Mouse (Biotinylated, HEK293, His-Avi) is the recombinant mouse-derived CD28 protein, expressed by HEK293, with C-Avi;C-hFc labeled tag.
- Species: Mouse

Background
CD28 Protein, a key player in T-cell activation, is involved in inducing cell proliferation, cytokine production, and promoting T-cell survival. It enhances the production of IL4 and IL10 in T-cells when combined with TCR/CD3 ligation and CD40L costimulation. CD28 Protein exists as a homodimer through disulfide-linkage and interacts with DUSP14. It binds to CD80/B7-1 and CD86/B7-2/B70, and also has an interaction with GRB2 (By similarity).

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
