Hyaluronan-binding peptide, biotin labeled TFA, is a bioactive peptide. (This peptide is biotinylated through a C-terminal GGGSK spacer and binds to hyaluronan. Hyaluronan (HA) is a non-sulfated glycosaminoglycan found in the extracellular matrix and on cell surfaces. It plays a significant role in fertilization, embryonic development, wound healing, angiogenesis, leukocyte transport to inflamed tissues, and cancer metastasis. This peptide has been demonstrated to block the interaction between HA and CD44 receptors and inhibit T-cell proliferation.)
