4-Hydroxy-3-Nitrophenyl Acetate-PE

NP-PE (Phycoerythrin) is an immune complex. Its formation and transport depend on the complement system, specifically through complement receptors CR1 and CR2. These receptors are expressed on the surface of B cells, aiding them in capturing and transporting immune complexes. NP-PE (Phycoerythrin) can be used to study the mechanisms by which B cells capture and transport immune complexes in lymph nodes.
