In electrophoresis experiments or other nucleic acid separation experiments, EB (Ethidium bromide, EtBr) is commonly used as a non-radioactive Marker to identify and display nucleic acid bands. EB is a dark red, non-volatile crystal that is slightly soluble in water. It emits reddish-brown fluorescence when exposed to ultraviolet light. Although EB is a highly effective color developer, its high risk still needs your special attention.

EB is a strong mutagen (possibly causing a genetic hazard) and is directly toxic to direct exposure. EB can be absorbed through the skin, so all direct contact with EB should be avoided. EB is irritating to the skin, eyes, mouth and upper respiratory system. The EB should be sealed securely and stored in a dry, dark place.

Ultraviolet radiation refers to optical radiation having a wavelength in the range of 100 nm to 400 nm. Generally, 100 nm to 280 nm is referred to as UVC, 280 nm to 315 nm is referred to as UVB, and 315 nm to 400 nm is referred to as UVA. Among them, the most used gels are 280nm-315nm UV.

Studies have shown that the harmful effects of ultraviolet light are mainly due to the action of ultraviolet light on deoxyribonucleic acid (DNA). The most harmful effects are cell death, and other effects include mutation, carcinogenesis, interference with DNA, ribonucleic acid (RNA) and protein synthesis, delays in cell division, and changes in permeability and motility.

1. Ultraviolet light damage to the eye Cataract is considered to be the main cause of excessive ultraviolet radiation. After ultraviolet light irradiation, most of the radiation is absorbed by the corneal epithelial nucleus, resulting in nuclear swell, fragmentation and cell death, and even damage to the cornea and The lens causes turbidity. In general, ultraviolet radiation increases and human cataract patients increase.

2. Ultraviolet light has an accumulating effect on the damage of human skin by ultraviolet light. Its main mechanism is that after the protein is irradiated by ultraviolet light, it forms a photolysis product. In addition, its solubility and viscosity, sensitivity to thermal denaturation and fluorescence, etc. Significant changes in both physicochemical and optical properties. The effect of ultraviolet light on the skin is divided into acute and chronic effects. The acute effect is characterized by erythema. The symptoms are edema and peeling. The systemic symptoms include chills, fever, nausea, and rare circulatory failure. Chronic effects such as skin aging, pigmentation, accelerated aging, and even tumors. Mild skin appears edematous erythema, severe cases may appear blisters or bullae, but also accompanied by shock, fever, chills, nausea, palpitations and dizziness.

3, the impact of ultraviolet light on other parts of the ultraviolet radiation on the immune system, some components of the immune system are present in the skin, the skin is exposed to ultraviolet light, so that the immune system is exposed to ultraviolet light, so that its function is interfered. Studies have shown that the immunosuppressive effects of ultraviolet radiation can lead to skin cancer, while causing some infectious diseases and other diseases.

The effects of EB and ultraviolet radiation on experimental personnel, especially female experimental personnel, are enormous, and even affect the reproductive system of women, which in turn affects the production and development of the next generation. Dongsheng Innovation's special blue-light gel imaging system will be for you. The experiments provide safe and reliable laboratory instruments.
