C3 Peptide P16 

C3 Peptide P16, is a 16 amino acid synthetic peptide derived from human C3d, a fragment generated in trypsin-cleaved C3. C3 Peptide P16 enhances in vitro phosphorylation of pp105 and pp100, a cellular component presenting in the human B lymphoma cells^[1][2].

C3 Peptide P16 (7.4 μM; 18 h) triggers in vitro and in vivo phosphorylations and in vitro proliferation of human B lymphocytes, depending on the stage of cell differentiation^[1].
C3 Peptide P16 (7 nM; 60 min; 4 ℃) induces in vivo tyrosine phosphorylation of pp105 and (15 μM; 6-8 d) enhances proliferation only of CR2-pos. but not of CR2-neg. cell lines in vitro^[1].
C3 Peptide P16 (7.4 μM; 18 h) also induces in vivo tyrosine phosphorylation of pp100 and in vivo proliferation of only small dense resting B lymphocytes and not other B lymphocyte subpopulations nor T lymphocytes^[1].
C3 Peptide P16 (0.3-10 μM; 3 min; 33 ℃) dose-dependently regulates pp105 phosphorylation, as well as C3d fragment present in trypsin-cleaved C3^[2].
