Endogenous peptide inhibitor of CXCR4, hSA(408-423) peptide
EPI-X4 (endogenous peptide inhibitor of CXCR4) is a fragment identified from a blood-derived peptide library, corresponding to residues 408-423 of human serum albumin (hSA). EPI-X4 is a highly specific endogenous CXCR4 antagonist which is evolutionarily
