Vectofusin-1
Based on 1 Customer Validation
Vectofusin-1 is a histidine-rich cationic amphipathic peptide derived from the LAH4 (HY-P0311) peptide family, and also acts as a Viral entry enhancer. Vectofusin-1 promotes the adhesion and fusion of retroviral/lentiviral vectors with cell membranes during viral entry, thereby improving transduction efficiency. Vectofusin-1 potently enhances lentiviral transduction of cells.

Description
In Vitro
Vectofusin-1 (12 μg/mL; 6 h) potently enhances the transduction efficiency of multiple lentiviral and retroviral pseudotypes in umbilical cord blood-derived hCD34+ hematopoietic stem/progenitor cells, resulting in a GFP+ cell proportion ranging from 57.5% to 79.4%, with no detectable cytotoxicity[1].
Vectofusin-1 (0-35 μg/mL; 5 days) enhances the transduction efficiency of GALVTR-LV in umbilical cord blood-derived hCD34+ hematopoietic stem/progenitor cells, with an EC50 of 6 μg/mL and a maximum average transduction efficiency of up to 67%[1].
Vectofusin-1 (0-100 μg/mL; overnight) has a median toxic concentration (TC50) of 60 μg/mL against umbilical cord blood-derived hCD34+ hematopoietic stem/progenitor cells, resulting in a 1-log safety index (TC50/EC50 = 10)[1].
Vectofusin-1 (12 μg/mL) effectively enhances the transduction efficiency of VSV-G-pseudotyped lentiviral vectors in umbilical cord blood-derived hCD34+ hematopoietic stem and progenitor cells (HSPCs), with the proportion of GFP-positive cells ranging from 76.2% to 82.7% in both total cell and subset analyses, which is comparable to the efficacy of Retronectin[2].
Vectofusin-1 (12 μg/mL) effectively enhances the transduction efficiency of VSV-G-pseudotyped lentiviral vectors in bone marrow-derived hCD34+ hematopoietic stem and progenitor cells (HSPCs); in analyses of total cells and subpopulations, the proportion of GFP-positive cells ranges from 69.8% to 74.8%, with a mean vector copy number (VCN) of 6.0 per cell, which is comparable to the efficacy of Retronectin[2].

Result:Detected equivalent numbers of hCD45+ human cells in peripheral blood, thymus, spleen, and bone marrow compared to untreated or Retronectin-treated cells.
Achieved engraftment of transduced GFP+ hCD45+ cells at least as robust as with Retronectin.
Observed active human thymopoiesis, with efficient transduction of immature CD3-low double-positive hCD4/hCD8 cells and mature CD3-high single-positive hCD4 and hCD8 T cells in the thymus.
Detected active human B lymphoid development (hCD19+ cells) in the spleen, which was efficiently transduced.
Detected and transduced human hematopoietic stem cells (hCD34+ hCD45+ cells), monocytes (hCD14+ cells), and granulocytes (hCD11b+ cells) in the bone marrow.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
