VisuFect® 100 Gene Delivery Reagent
Description   VisuFect® 100 is made up of an organic compound and chemically for the uptake by cells without a transfection reagent. VisuFect® 100 can deliver oligonucleotides in which a user id interested such as DNA aptamers, siRNAs, miRNAs or antisense RNAs into cell without any transfection reagent. Since VisuFect® 100 contains fluorophore, the researcher can easily monitor efficiency of transfection. VisuFect® 100 is a customized product which made by customer’s own sequence. VisuFect® 100 reagent is ideal for transfection of various cells, including primary difficult-to-transfect cells zygote, egg and sperm. Transfection can also be performed regardless of the presence or absence of serum. VisuFect® 100 demonstrates superior transfection efficiency and minimal toxicity compared with the lipid-based or other polymer-based transfection reagents.
Figure 1. VisuFect® 100 results from various cell types. VisuFect® 100 emitted red light. Red means that VisuFect® 100 with oligonucleotides enter the cells.
Application   ● Transfer short oligonucleotides (e.g. DNA, RNA, siRNA, miRNA) ● Transfection of primary difficult-to-transfect cells, including human embryonic stem (ES) cells, human fibroblast cells ● In vivo gene delivery zygote, egg and sperm (e.g. zebrafish, xenopus, porcine etc) ● Development study ● Gene delivery study according time lap ● HTS study (high-throughput)
Feature   ● Organic compound, hydrophilic and fluorescence-label ● Chemically modified reagent for gene delivery (Clathrin-mediated internalization) ● Customized product which made by customer’s own sequence ● Source : 10-30 mer oligonucleotide            DNA aptamers, siRNAs, miRNAs or antisense RNAs, antisense oligonucleotides ● Easy monitoring gene delivery efficiency : fluorescence-label (Figure 2) ● Fast and simple gene delivery with no need to change media ● High efficiency regardless of the presence or absence of serum ● Low cytotoxicity (Figure 3) ● Easy to handle : Ready-To-Use, Customized synthetic product
Figure 2. The confocal microscopy result after treatment of VisuFect® 100 to porcine eggs (for 18h) and sperm (for 2h). VisuFect® 100 was diluted with medium (that was) used for porcine cell culture. VisuFect® 100 emitted 694nm waves and red light.
Figure 3. Low cytotoxicity of VisuFect® 100. A comparison of development rate of blastocyst between VisuFect® 100 treatment and microinjection using by same siRNA. It shows almost same development rate between control and VisuFect® 100 samples. However, in the case of microinjection, the development rate of blastocyst was reduced.
