HN-1

HN-1 is a tumor-specific internalizing peptide. HN-1 internalizes through receptor-mediated, energy-dependent, Clathrin-mediated endocytosis. HN-1 preferentially binds to invasive head and neck squamous cell carcinoma and is selectively internalized. HN-1 enhances the transfer of liposome-DNA complexes to head and neck squamous cell carcinoma. HN-1 can be used for research on head and neck squamous cell carcinoma.

Biological Activity

Description

In Vitro

HN-1 is internalized by attached HNSCC cell lines such as MDA177Tu, UMSCC1, SCC-25, CAL-27, and FaDu, but not by suspended HNSCC cells or normal HOK16B/NOE/NHDF cells, via energy-dependent clathrin-mediated endocytosis and endosomal localization^[2].
HN-1 (>500 μM) blocks FITC-labeled HN-1 internal fluorescence in HNSCC cells, supporting specific HN-1-mediated uptake rather than free-dye labeling^[3].

In Vivo

Cy5-labeled HN-1-PKCε is taken up by HNSCC xenograft tumors and reduces overall HNSCC tumor growth in mice^[3].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
