Description

EVO Transfer, DNA is a nano polymer transfection reagent developed and synthesized by our company. This reagent is synthesized using nanotechnology and is a new generation of non viral transfection reagents. Due to the application of nanotechnology, EVO Transfer, DNA exhibits excellent low toxicity and high efficiency performance during cell transfection.This product is used for in vivo transfection of DNA.

Features

The method is simple and fast, with no obvious inflammatory response to animals, and is safe for operators.

Application

1. In vivo studies of gene therapy in animals
2. In vivo studies on RNA interference in animals
3. In vivo study of protein function in animals

Note

1. The preparation of transfection complexes is carried out at room temperature. Before operation, please restore the nucleic acid, transfection reagents, diluents, etc. to room temperature. Low temperature operation, long-term storage, minimal or no use of diluents, and mixing nucleic acids and transfection reagents in large reaction systems may cause the aggregation of transfection complexes and result in turbidity. In general, slight turbidity does not affect the transfection effect. If turbidity needs to be avoided, it is recommended to operate at room temperature, ready to use, using diluents, and avoiding large amounts of preparation at once.
2. Nucleic acid dosage. The initial dose for intravenous administration of nucleic acid is 0.625mg/kg. The higher the dosage, the better the effect, with the standard of not causing animal inflammation and death. The following table shows some common dosages and volumes of administration.

Table 1. Dosage and volume of administration

Administration route	Nucleic acid dosage	Maximum administration volume	Administration route
Adult mice	Caudal vein	10-50μg	200μl-600μl
	Ventricle	1-2.5μg	5μl
	Peritoneum	100μg	0.6ml-1ml
	Testis	3-5μg	10μl
Nude mice	Subcutaneous tumor	10-50μg	100μl
Adult rats	Ventricle	2-5μg	20μl
	Caudal vein	500μg-2.25mg	1-2ml
Adult rabbit	Pulmonary and tracheal perfusion	300-700μg	300-700μl

• Requirements for nucleic acid testing. It is recommended to dissolve with pure water and ensure high purity and endotoxin free. The recommended concentration of nucleic acid is 0.5-1μg/μl. The purity of nucleic acid will greatly affect the transfection efficiency, so it is necessary to use high-purity and high-quality nucleic acid.
• The amount of EVO Transfer, DNA used. In general, nucleic acid (μg) and EVO Transfer, DNA (μl) are used in a ratio of 1:2.
• Tail vein injection: To maintain the working concentration of the transfection complex and blood isotopes during injection, it is necessary to dilute with solutions such as glucose (preferred) and physiological saline.

The following table shows the composition of each component (nucleic acid concentration 1μg/μl) when a tail vein injection of 20g body weight mice was administered at a dose of 100μl at a dose of 0.625mg/kg.

Table 2. Composition of transfection complexes after tail vein injection of 100μl

100μl of transfection complexes	Nucleic acid diluent	12.5μg(12.5μl)nucleic acid
		12.5μlwater
		25μl 10% glucose solution
	Transfection reagent diluent	25μl transfection reagent
		25μl 10% glucose solution

• Local injection: First, determine the maximum volume that needs to be finally injected. After determining the maximum volume, the dosage is determined based on the ratio of nucleic acid (μg): transfection reagent (μl)=1:2. For example, when the local injection volume is 30μl, the composition of each component is determined, with a nucleic acid concentration of 1μg/μl (which can be dissolved in physiological saline or pure water).

Note: When not using or using less diluent, mixing nucleic acid and transfection reagents can easily produce turbidity. Slight turbidity does not affect the experiment. If turbidity needs to be avoided, it is recommended to use diluent and avoid preparing in large quantities at once.

• Table 3. Composition of Local Injection 30μl Transfection Complex

30μlof transfection complexes	Nucleic acid solution	8μg(8μl)nucleic acid
	Nucleic acid diluent	6μl
	Transfection reagent	16μl transfection reagent
