Active Recombinant Human ICOS, MIgG2a Fc-tagged

• Cat.No.: ICOS-1531H
• Product Overview: The extracellular domain of human CD278 [ICOS] (NP_036224.1) (Glu21-Leu139) is fused to the N-terminus of the Fc region of mouse IgG2a.

Specification

• Species: Human
• Source: CHO
• Tag: Fc
• Protein Length: 21-139 a.a.
• Description: The protein encoded by this gene belongs to the CD28 and CTLA-4 cell-surface receptor family. It forms homodimers and plays an important role in cell-cell signaling, immune responses, and regulation of cell proliferation
• Form: Lyophilized from 0.2μm-filtered solution in PBS.
• Bio-activity: Measured by its ability to inhibit human T cell proliferation induced by rhB7-H2/Fc Chimera in the presence of anti-CD3.
• Molecular Mass: 40 KDa (monomer)
• AA Sequence: Glu21-Leu139
• Endotoxin: <0.06 eu/μg="" as="" determined="" by="" lal="">
• Purity: >98%, by SDS-PAGE under reducing conditions.
• Stability: Stable for at least 1 year after receipt when stored at -20°C. Working aliquots are stable for up to 3 months when stored at -20°C.
• Reconstitution: Reconstitute at 100μg/ml in sterile PBS.
• Warning: Avoid freeze/thaw cycles.
