Klotho 20mg

alphaKlothoLR is a patented, long–release version of the recombinant Klotho protein, which contains specific amino acid sequences, linkers, and an albumin binding group that allows for a sustained delivery of Klotho with cellular activity up to 19 days.

This research-grade construct combines α-Klotho protein with a proprietary 29-amino acid albumin binding peptide (GGSGGSGGSGGRLIEDICLPRWGCLWEDD). The modification enables strong albumin binding affinity (<20 nM) while maintaining native FGF23 binding activity (15-30 nM).

Produced through recombinant expression with rigorous third-party testing. Each batch includes HPLC and LC-MS verification to confirm molecular identity and purity standards. Complete analytical documentation supports laboratory applications investigating protein-albumin interactions, FGF23 signaling pathways, and albumin binding mechanisms.

For in vitro research use only.
