SLLK, Control Peptide for TSP1 Inhibitor (TFA) is a control peptide for LSKL, which is a Thrombospondin (TSP-1) inhibitor.
Akita mice treated with 30 mg/kg LSKL have significantly increased nephrin expression, greater than twofold, compared with renal lysates from either saline controls or SLLK-treated mice[1].TGF-β1 is significantly lower (0.10±0.01 pg/mL) in the plasma of mice receiving LSKL compared with that in plasma of mice receiving SLLK control peptide at day 42 (0.20±0.02 pg/mL; P=0.0001). MRNA expression is assessed in the suprarenal aortic lysates obtained from mice receiving SLLK and LSKL peptides[2].
