Human Anti-CD28 (clone Theralizumab) scFv-Fc Chimera
CAT#: VS-0325-FY106
The anti-CD28 scFv-Fc antibody specifically binds to CD28, a co-stimulatory molecule critical for T cell activation. Its scFv-Fc format enhances its ability to modulate immune responses by targeting CD28. This antibody is valuable for research on T cell signaling pathways and immune checkpoint mechanisms.
