KLD-12 TFA 

KLD-12 TFA is the TFA salt form of KLD-12 (HY-P2263). KLD-12 TFA is a self a 12-residue self-assembling peptide that is used in tissue-engineering. KLD-12 TFA combined with SDF-1 self-assembled polypeptide enhances chondrogenic differentiation of bone marrow stromal cells (BMSCs). KLD-12 TFA hydrogel can fill full-thickness osteochondral defects in situ and improve cartilage repair^[1][2][3].
