Recombinant Human CD52 Protein, hFc-tagged, Alexa Fluor 647 conjugated

• Cat.No.: CD52-393HAF647
• Product Overview: Alexa Fluor 647 conjugated recombinant human CD52 (Gly25-Ser36) protein was fused to human IgG1 Fc tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Description: CAMPATH-1 antigen, also known as cluster of differentiation 52 (CD52), is a glycoprotein that in humans is encoded by the CD52 gene.It is widely expressed on the cell surface of immune cells, such as mature lymphocytes, natural killer cells (NK), eosinophils, neutrophils, monocytes/macrophages, and dendritic cells (DCs).ligation of cell surface CD52 molecules may offer costimulatory signals for T-cell activation and proliferation.
