Handling, storage & reconstitution

General guidance for this class

Reference standards in the Cell-Penetrating class are typically shipped as lyophilized powder and stored desiccated at −20 °C protected from light. Once reconstituted in bacteriostatic water or the assay-appropriate buffer, aliquot and store at −80 °C to minimize freeze–thaw cycles. Confirm handling requirements against your institutional biosafety and radiation protocols before use.

Mechanism & research applications

Pep-1 sits within the Cell-Penetrating research class (CPC reference TAT-001). CPPs cross cellular membranes through energy-independent direct translocation and/or endocytic uptake driven by cationic residues (arginine-rich sequences) or amphipathic architecture. They are typically conjugated to a cargo of interest. Investigators typically incorporate Pep-1 as a reference standard, tool ligand, or substrate in the assay contexts listed above. Fluorescent-conjugate flow cytometry and confocal imaging are the standard uptake readouts.

Studied for

  • Intracellular cargo delivery (peptides, siRNA, proteins)
  • Endosomal-escape and trafficking studies
  • In vitro screens of CPP variants for uptake efficiency
  • Structure–activity work on cationic / amphipathic CPPs

Frequently asked

What is Pep-1?

Pep-1 (CPC catalog code TAT-001) is a synthetic cell-penetrating peptide (cpp) in the cell-penetrating category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is Pep-1 studied for?

Published and internal research programs use Pep-1 as a reference standard in cell-penetrating workflows — for example, intracellular cargo delivery (peptides, sirna, proteins) and endosomal-escape and trafficking studies. Human clinical evidence is not established.

Is Pep-1 FDA-approved for human use?

No. Pep-1 is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.

How is Pep-1 typically used in the lab?

In a cell-penetrating workflow, Pep-1 is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Fluorescent-conjugate flow cytometry and confocal imaging are the standard uptake readouts.
