(KKEEE)3K acetate is a kidney-targeting peptide. (KKEEE)3K enters renal tubular cells via megalin receptor -mediated endocytosis. (KKEEE)3K acetate can be used in the research of renal drug delivery [1].
In Vitro, (KKEEE)3K (48 h) acetate conjugation to Bacteroides fragilis OMV-scFv significantly enhances cellular uptake by mouse primary renal tubular epithelial cells[1].
