Anti-Human CD28 Recombinant Antibody Fab Fragment (HuTN228) (CAT#: TAB-069LC-F(E))

HuTN228 is a recombinant monoclonal antibody targeting CD28. It is a humanized antibody with potential applications in transplant rejection treatment. HuTN228 antibodies specifically recognize the CD28 antigen through interactions in the V-region. TAB-069LC-F(E) antibody is the Fab fragment antibody form of TAB-069LC antibody. Fab fragments, the antigen-binding domains of an antibody molecule, consist of two amino acid chains composed of VH+CH1 and VL+CL domains.
