■■■■ What’s HVJ Envelope?
HVJ Envelope(HVJ-E) is a novel and unique vesicle that employs the membrane fusion
ability of the envelope of Sendai virus (Hemagglutinating virus of Japan; HVJ). The
genome RNA of HVJ is completely inactivated to use HVJ-E in biosafety level 1(BSL1)
laboratories.
HVJ-E is known for its ability to incorporate a variety of molecules, such as plasmid
DNA, siRNA/miRNA or proteins and introduce them into the cytoplasm via membrane
fusion. HVJ-E can also be used as a cell fusion reagent.

One day after stimulation of mouse splenocytes with PMA/ionomycin, T cells were isolated. Cas9 protein and PPIB-targeting gRNA
were then transfected using GenomONE-GE, product C, or product T (competitors). Two days after transfection, genome editing
efficiency was evaluated using T7 endonuclease I mismatch cleavage assay.
GenomONE - GE・Optimal for transfection of Cas9 protein and gRNA
・Applicable to transfection of Cas9 protein, gRNA and donor DNA (knock-in)
・Applicable to difficult-to-transfect cells (e.g., U-937, Jurkat, and mouse primary T cells)
■■■■ Cas9 protein and PPIB-targeting gRNA transfection in HeLa and U-937 cells
Cas9 protein and PPIB-targeting gRNA were transfected into HeLa and U-937 cells using GenomONE-GE, product C, or product T
(competitors). Two days after transfection, genome editing efficiency was evaluated using T7 endonuclease I mismatch cleavage
assay.

As a kinesin-like motor protein, Eg5 (KIF 11) is essential for the
formation of spindle microtubules during cell division, and when
its function is inhibited, cell division is stopped and apoptosis is
induced. Based on such a phenomenon, the efficiency of
transfection of siRNA is quantitatively evaluated by the WST-8
method (a method for determination of viable cell count).

KALA peptides can destabilize the endosomal membrane and
enhance the transfection efficiency of non-viral gene delivery
vectors.

GenomONE - GX・A novel gene delivery vector composed of a lipid-like substance and HVJ-E
・The GenomONE-GX Enhancer suppresses innate immune responses by plasmid DNA and
improves transgene expression.
・Transgene expression is enhanced by GenomONE-GX using a combination of KALA peptides.
■■■■ TurboGFP expression
Various cell lines were transfected with a reporter plasmid encoding TurboGFP under a CAG promoter using either GenomONE-GX(with or without the KALA peptide) or Product L (a competitor), following the manufacturer’s instructions.
※The KALA peptide is not included in the GenomONE-GX kit and hence the KALA peptide solution needs to be prepared in advance.

■■■■ Mechanism of Enhancer
The GenomONE-GX Enhancer inhibits innate immune signaling
in response to the recognition of exogenous DNA. Hence, it
can be used to increase transgene expression, which is
intrinsically suppressed by innate immune signaling.

・Optimal for transfection of protein in vitro
■■■■ Retrograde Injection of siRNA into Rat Submandibular Gland(in vivo)
rCLCA siRNA was injected in retrograde fashion into the
submandibular glands of rats, using GenomONE-Neo .
Forty-eight hours later, specific suppression of expression of
Cl- channel protein was demonstrated on the siRNA-
injection side by immunostaining.
rCLCA siRNA was injected in retrograde fashion into the
submandibular glands of rats, using GenomONE-Neo.
Forty-eight hours later, secreted saliva was collected while a
drug stimulating salivary release (pilocarpine) was administered.
Analysis of the concentrations of electrolyte in the saliva
collected revealed a significantly higher Cl- level in the group
with injection of rCLCA siRNA than in the control group
(scrambled siRNA-injection group), confirming the efficacy of
rCLCA siRNA injection in specifically suppressing Cl-
reabsorption. Reabsorption of Na+ and K+ remained unaffected.
Injection of siRNA, targeted at cystic fibrosis transmembrance conductance regulator (CFTR), also resulted in specific suppression of
Cl- reabsorption.

GenomONE - CF・A cell fusion reagent with low cytotoxicity and
high fusion activity・Applicable to hybridoma preparation and
nuclear transfer・An alternative method to PEG and electrofusion for cell fusion
■■■■ Comparison with PEG method in the fusion of different types of cell
■■■■ Comparison with PEG method in hybridoma preparation
Rat MSC cells (rat bone marrow-derived mesenchymal stem cells) labeled with red fluorescence were combined with rat primary
cardiac myocytes labeled with green fluorescence in Cell Fusion Buffer. As a result, fused cells (yellow) were formed (GenomONE-CFsuspension method). Fused cells adhering to the plate were also observed after 1-2 days of culturing. In the PEG-treated group, high
cytotoxicity appeared immediately after cell fusion, reducing the number of fused cells obtained.
Normal BALB/c mouse splenocytes not sensitized with antigen were fused to X63-Ag8.653 myeloma cells using GenomONE -CF or
PEG1500. Beginning the following day, half of the culture medium (10%FBS/RPMI1640) was replaced with HAT medium at five
points of time(Days 1, 2, 3, 5, and 8), and the growth of colonies in each well was assessed on Days 10 - 11 to determine the
hybridoma-positive rate(an indicator of efficiency of fusion). On Day 12, mouse antibody level (IgG + IgA + IgM) in the supernatant
was measured by ELISA, to calculate the antibody production-positive rate. The effect of adding a commercially available hybridoma
supplement to the medium after fusion was also assessed (supplement was also added to the HAT medium).
Use of GenomONE -CF resulted in more efficient formation of antibody-producing hybridoma than that of PEG. The efficiency of cell
fusion mediated by GenomONE -CF was increased by the addition of hybridoma supplement to the medium used for incubation after
cell fusion.
