Recombinant Human CD28, HIgG1 Fc-tagged

Cat.No.: CD28-378H
Product Overview: The extracellular domain of human CD28 (AAA60581.1) (Asn19-Pro152) is fused to the N-terminus of the Fc region of human IgG1 was expressed in CHO cell.
Description: The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, andT-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms havebeen found for this gene.
Source: CHO cells
Species: Human
Tag: HIgG1 Fc-tagged
Form: Lyophilized from 0.2μm-filtered solution in PBS.
Bio-activity: Measured by its ability to inhibit IL-2 secretion by stimulated Jurkat human acute T cell leukemia cells.
