Phe-Lys(Trt)-PAB is a cathepsin-cleavable peptide-PAB linker used in antibody-drug conjugate (ADC) research. It couples cytotoxic payloads to antibodies via a protease-sensitive spacer that remains stable in circulation and is cleaved by lysosomal cathepsins after internalization to release the payload. Supplied as a 5 mg solid for research use; store as powder at -20°C.

  • Cathepsin-cleavable peptide spacer.
  • Enables controlled lysosomal release of payloads.
  • Stable under physiological conditions.
  • High purity suitable for research applications.
  • Powder storage at -20°C extends shelf life.
