This antibody recognizes an extracellular epitope of CD28, a disulfide-linked homodimeric type I glycoprotein (monomer of MW 44 kDa) which is a critical costimulatory receptor of T cells.
Applications
Flow Cytometry
Dilutions
Flow Cytometry: The reagent is designed for analysis of human blood cells using 20 µl reagent / 100 µl of whole blood or 106 cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests.
